-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.

FUNCTION
|
DEOXY/OXY BLOOD
|
LEFT ATRIUM
|
-collects oxygen-rich blood from the lungs then forces through the mitral valve into the left ventricle
|
OXY
|
LEFT VENTRICLE
|
-largest and strongest chamber, wall is only half an inch thick and it pushes blood through aorta valve into the body
|
OXY
|
RIGHT ATRIUM
|
-collects oxygen-poor blood returning coming back from the body and then it forces it through the tricuspid valve then into the right ventricle.
|
DEOXY
|
RIGHT VENTRICLE
|
- collects oxygen-poor blood from the right atrium and then forces it through the pulmonary valve then into the lungs
|
DEOXY
|
PULMONARY ARTERY
|
-carry blood from the heart to the lungs to pick up oxygen
|
DEOXY
|
AORTA
|
- the largest artery carries oxygen-rich blood from the heart to the rest of the body
|
OXY
|
PULMONARY VEINS
|
-carry oxygen-rich blood from the lungs back to the heart
|
OXY
|
SUPERIOR VENA CAVA
|
-oxygen-poor blood from the upper body returns to the heart through the superior vena cava
|
DEOXY
|
INFERIOR VENA CAVA
|
-oxygen-poor blood from the upper body returns to the heart through the inferior vena cava
|
DEOXY
|
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)
|
tricuspid controls blood flow from the right atrium to the right ventricle and mitral controls flow from the left atrium to the left ventricle
|
Deoxy/oxy
|
CHORDAE TENDINAE
|
- bring right ventricular walls closer together during contraction. -pull the AV Valves open during atriole systole
|
Left oxy
Right deoxy |
SEMI LUNAR VALVES (Pulmonary & Aortic)
|
-pulmonary valve control blood flow from right ventricle to the pulmonary arteries and aortic valve controls blood from left ventricle to aorta
|
deoxy/oxy
|
SEPTUM: separates left from right- /
