A

The systemic circulation sends oxygenated blood from the heart and returns deoxygenated blood back.
Blood vessels exit in parallel circuits
Route that blood takes:
* Left ventricle to……
* aorta to…..
* arteries to……
* arterioles to ……..

Q

Describe the pulmonary circulation

A

The pulmonary circulation sends deoxygenated blood to the lungs from the heart for reoxygenation. Once reoxygenated the blood is sent back to the heart
Series circuit
Route that blood takes:
* Right ventricle to……
* pulmonary artery to…..
* arterioles to……
capillaries to…..
* venules to…….
* pulmonary vein to ……
* left atrium and ventricle
