Describe the process of external gas exchange. What gases are being changed? Why?

External gas exchange is between the air and lungs. Oxygen goes into the blood from the air via alveoli. Carbon dioxide goes into alveoli into air from blood. You breath out carbon dioxide because of cellular respiration. O2 + glucose → H2O + CO2 + ATP

Procedure: 

Observations:

Part A - Aerating of lime water had no changes (left test tube). The test tube that had carbon dioxide aired into by a human turned cloudy ( right test tube).

Part B - The beaker to the left turned into a light green was aerated which means it is neutral. The beaker to the right had distilled water and had a human being breathed carbon dioxide out into it turned into a vibrant yellow which means its highly acidic.

Part C -

Amount of breaths taken in 60 seconds; 28, 25 and 18.
Amount of breaths taken in 30 seconds; 18, 14 10.

The results which were taken in thirty seconds are slightly higher (if multiplied by 2) to equal out the amount of time given to breath. This test was mostly subjected to human error so therefore it is not conclusive.

Questions:

Part A

1. What does a change in color in the lime water indicate?
A change in color indicates chemical change.

2. What is the purpose of the control test tube?
To compare the difference between how the lime water is affected by oxygen and carbon dioxide.

Part B

3. What does the change in color of the universal indicator mean?
When your body breathes out C02 and it combines with H2O, the pH levels change and the H2O becomes acidic.

4. What is the purpose of the control beaker?
The purpose is to compare and see the results of both test tubes

5. Explain what is happening in the test beaker of water.
Both of the beakers remained the same until the universal indicator was added. The beaker that was aerated turned into a light green color, symbolizing that it is neutral. The beaker that we breathed out carbon dioxide into turned yellow, symbolizing it is acidic.

6. Why does your blood not become acidic?
 Our blood contains hydrogen with hemoglobin molecules which regulates our pH levels. That keeps are blood from not becoming acidic.

Part C

8. Explain the results for Part C. What happened to the breathing rate? What mechanism is responsible for this change?
I think part C failed due to human error. The participants continuously lost count throughout the course of the test.

Lung Inflation and Deflation Lab

This lab is a way to show the mechanism of breathing. When the diaphragm goes down, the lung inflates. when the diaphragm goes back up, the lung deflates.

Respiratory System - Free Divers Are Immoral

The respiratory system is made up of several organs and structures, including the lungs, windpipe, diaphragm and alveoli. It is responsible for taking in oxygen and taking out carbon-dioxide.

The average time an adult can hold their breath is between 30 and 60 seconds. This set quantity has to do with the buildup of carbon dioxide than the lack of oxygen, which your body stores in muscle proteins called myoglobin. But free divers (people who practice the sport of diving underwater without using equipment like scuba gear) have different techniques, such as hyperventilation, to decrease the amount of carbon dioxide in the blood, allowing them to hold their breath for remarkable long times. An example is Denmark's Stig Severinsen who currently holds the Guinness World Record for the longest free dive. In 2010, he held his breath underwater for 22 minutes.

Exercise Science - Fitness Goal

My fitness goal: My fitness goal is to increase my flexibility because I feel as though my body is above average in all six departments we have measured except for flexibility. 

How you can measure it (specific fitness test): I scored a 8/17 on the "FitNation Flexibility Test." This scored surprised me because I have been working on my flexibility for quite some time. After doing research, visiting a chiropractor and physiotherapist, I have concluded the fact my body is not flexible what so ever is because of the amount of stress I put on my muscles on a weekly basis. I was recommended to do only a certain amount of training which would allow my body to become less injury prone. My goal is to score a +14 on the next "FitNation Flexibility Test" which will take place near winter break (Every 2-3 months). 

A workout / app that will help you meet your goal: After consulting my physiotherapist and chiropractor, they insisted that I began doing "active isolating stretching." AIS is a newly discovered stretching method which makes your body go beyond its stretching limits which allows you to increase your flexibility by %10-%15 if the structure of the stretching routine is correct. I took on the responsibility of trying to find a stretching routine which would give me the success I desired. 

I found this amazing routine constructed by The Northern Quarter Clinic on Youtube. I have been doing this routine twice on a daily basis and so far I have seen a huge difference doing it on a  consistent basis.

Crash Course Video

Crash Course Video Link: https://www.youtube.com/watch?feature=player_embedded&v=9fxm85Fy4sQ

The respiratory system takes the oxygen needed for the body from the out side of the body and brings it into the lungs where it is diffused through the lungs and into the blood stream. The circulatory system carries the oxygenated blood throughout the body where oxygen is exchanged for waste materials, for example, carbon dioxide, which is carried back to the lungs where it is let into the atmosphere (exhalation) in exchange for Oxygen (inhalation). One of the interesting things I've learned from watching the "Crash Course Video" was how animals obtain oxygen by the process called simple diffusion. This process allows animals to inhale oxygen without lungs, the oxygen goes into the animals, passes through wet membranes, and is then processed. Another interesting fact I learned is mammals and birds are warm blooded, they lose calories because their body needs to regulate it's body temperature which requires even more oxygen. 

 

 

Protein Activity

1. What type of bond is found in the primary structure (Amino acids)?

Polar peptide bonds are found between the amino acids.

2. Why does the secondary structure form (Alpha Helix)?

The secondary structure forms because of the polar peptide bonds. 

3. What created the 3rd structure? Why did your protein look different then everyone else's? 

The 3rd structure was created by the protein attraction or repelling each other. Mine looked different then everyone else's because I choose different proteins which causes different shapes because some proteins repel and some attract to each other.

4. How was the 4th structure created? 

The 4th structure was created by two or more polypeptides which got stuck together because two proteins attracted each other.

5. Would your protein have the same shape if you changed the primary structure? Explain.

No it would not because their would be different proteins which repel or attract each other which would make different shapes.

Heart Dissection

  

External Anatomy

The heart seems to be a maroon and dark purple color, but there is a huge color differential on different parts of the heart. It weighs less than a pound, it is also uneasy to control due to its slippery conditions.  When viewed from the front, the heart is triangular. The base of the heart has a broader top end, from which the vessels enter and leave the heart. The heart narrows down to a rounded point. It was easy to spot the four chambers of the heart, the right and left atria and ventricles. The aorta and pulmonary trunk seemed to be flappy. The inferior and superior vena cava was difficult to spot because it seemed to be much smaller and thinner than expected.

Internal Anatomy

The internal anatomy was awfully sickening. The left ventricle wall seemed much thicker than the right ventricle wall. It was noticeable different because I was able to feel the thick layer of muscle covering the left ventricle while the right ventricle seemed very thin. The semi-lunar valve, aortic valve, left and right valves seemed all similar. They were all glutinous and thin. They felt like pieces of gum, but stronger and a lot more durable.

Questions:

1. What was the most surprising thing about dissecting the heart?  Describe what your expectations were and if they were met.

The most surprising thing about dissecting the heart was being able to see how condensed the parts of the heart actually are. Even though the heart is very compact and much smaller in size then I imagined, it amazed me how something that is comparable to the size of my fist can manage to pump blood throughout my entire body.

2. Why are the atria and ventricles so different (compare their structure to their function)?

The atria are the upper chamber of the heart and the ventricles are the lower chamber. The Atria receive deoxygenated blood while the ventricles receive blood from the atria and force it out to the aorta or the pulmonary artery. The atria have thinner walls due to low blood pressure and the ventricles have thick walls due to high blood pressure.

3. Why is the left ventricle more muscular than the right?

The reason the left ventricle is more muscular than the right ventricle is because the right and left ventricles both have different jobs. The right ventricles job is to send deoxygenated blood to the lungs so the lungs can collect the CO2 and give away 02 to the blood. Meanwhile the left ventricle has to send oxygenated blood throughout our entire bodies which requires a lot more strength, therefore it is more muscular because the left ventricle is doing a lot more work than the right which causes it to enlarge due to its amount of strength building up.

4. What are functions of the heart valves?  Describe how the structure of the valves relates to their function (including chordae tendinae).

When the left ventricle relaxes, the aortic valve closes and the mitral valve opens, to allow blood to flow from the left atrium into the left ventricle. The left atrium contracts, allowing even more blood to flow into the left ventricle, When the left ventricle contracts again, the mitral valve closes and the aortic valve opens, so blood flows into the aorta.

Interim Report

I am the most proud of: The amount of happiness that comes from learning something you love. It's a rare occasion for me but I am proud of how we are being taught and the way my brain consumes new information in this program. 

The most interesting things I have learned about are:
The way blood is transported through our entire body, the different metabolic energy systems, and the variety of different exercise used to improve a certain aspect of your body. 

An example of when I really pushed myself in SuperFit is:
I haven't which has saved me from another hamstring tear, thank you Mrs. Phillips. 

I could make improvements in:

Encouraging others to try their best, bring a leader is a great quality everyone should have. 

I am really looking forward to:
Learning new fascinating things about the human body, especially human performance and how it can help us in our everyday lives. 

The Basics - WORK HABITS:

Attendance (classes missed and why) - I missed two classes due to sickness and an appointment with my lawyer.

Participation in field trips (woo kim, grouse grind, rock climbing) -I only went to woo Kim because I am not physically fit enough to do the grouse grind and I was absent during rock climbing. 

Lates (how many & reasons) - once, I forgot when the class started, it was flex day. 

Preparedness for class (gym strip &/or supplies) - N/A

Class time management (are you using your class time to complete your work?  engaged in class discussion? participating? following along? doing your best? or talking too much? ) -

I think I am doing everything pretty well mainly because I enjoy this class. I enjoy learning and I enjoy doing things in a variety of ways, which is what we have done this whole semester. 

Blog assignment completion - (out of 8 assignments) Comments?

I'm terrible at this. I definitely have to pick up my slack.

Grouse Grind

I wasn't able to attend the grouse grind field trip due to an injury, but I remember the previous time I went up the grouse grind which was 8 months prior to our field trip. I remember my inability to stay at a steady pace due to the build up of lactic acid. There was this burning sensation which was there continuously through out the whole 42 minute climb for me. My quadriceps, hamstrings, calves and shins. My heart rate and and breathing ratw varied depending on thr climb. For the most part it was steady, but on a certain inclines they both dramatically increased at the same time. My body temperate was probably at its highest point that it's ever been in my entire life, you were able to see the red blood vessels popping out of my skin. Glycolysis and aerobic system are the two metabolic systems being used in this physical activity. The grouse grind is a short walk which is less then 70-75% of your effort and lasts for about 30 seconds to a minute with short breaks In between each walk up the inclined hill. 

VO2 Max

My VO2 Max is 68.7, which is labeled as "excellent" according to the website used to calculate it. I think the metabolic engery system used is glycolysis because during the hill run, it is a burst of speed which lasts about 15-30 seconds and then a active rest period which is usually 40-60 seconds long. 

Biology - Heart Anatomy

-Coronary arteries and veins are the blood vessels that supply blood and carry blood away from the heart muscle. The left coronary arteries supply blood mainly to the left side of the heart and vice versa.  

STRUCTURE	FUNCTION	DEOXY/OXY BLOOD

First Post - Why Did You Take Co-op

Why did you take the co-op?

I took co-op because it will introduce new information and interesting subjects to me. It seems to be a class that I will enjoy and excel in. I hope this year's co-op program is a success.

 

What are your plans for next year?

I hope to enter the sports science program at Douglas College after I finish my heavy duty mechanic foundation program at VCC. It is important to me to learn about the human body and all the different aspects that consist of human performance because it is something I am passionate about.

 

 What activities do you like to do outside of school?

Activities I like to do on a daily basis are power lifting and playing soccer. Power lifting is something I was introduced to earlier this summer by FitNation; a group of personal trainers who help athletes excel in their sport. Most of our powerlifting consisted of exercises such as deadlifts, power cleans, bench press, press, and squats. Soccer is something I have been playing since my youth days and it is something I will continue to play until I am well past my prime.

 

 Have you done any fitness activities over the summer?

I have done only two fitness activities over the summer but I did them often. Like previously explained, soccer and power lifting are the two activities I like and often do, usually every second day I do one or the other.

 

 What are your fitness goals for the semester?

My only fitness goal is to gain flexibility. It is the one area I feel as though I am very poor in. I hope to gain flexibility so I can be less injury prone and protect my hamstring from another tear as well.
