Structure & function of the cardiovascular and respiratory systems
1) Vena cava
Vena cava makes sure that the deoxygenated blood back to the right atrium.
2) Right atria
This atrium receives deoxygenated blood from the vena cave so that it can pass it through.
3) Tricuspid Valve
This valve is located between the right atrium and right ventricle.
4) Right ventricle
The ventricle pumps the deoxygenated blood away from the heart to the heart.
5) Semilunar valve
The valve prevents blood flow (from going back) from arteries into the heart.
6) Pulmonary Vein
This pulmonary vein carries deoxygenated blood back to the heart so that it can get oxygenated
7) Pulmonary artery
Once the pulmonary vein brings deoxygenated blood back it goes to pulmonary artery so that this artery can carry the deoxygenated blood away fro
it can get oxygenated.
8) Left atria
The left atria collects the blood from the pulmonary vein so that is can go through the next stage of processing the blood so it should go
9) Bicuspid valve
When the blood passes the bicuspid valve they can go back because when the heart contracts the blood will get the push and the blood must go on
that it can’t go back.
10) Left ventricle
This is a thick muscle that contracts to pump blood oxygenated blood from the heart.
11) Aorta
The role of aorta is that it carries oxygenated blood away from the heart to muscles and organs and other places this artery carry's deoxygenated bl
