blood flow through the systemic circulation

step 1

oxygenated blood enters through the left

step 2

blood passes through the left av valve

step 3

blood enters the left ventricle

step 4

blood passes through aortic semulunar valve

step 5 

blood enters the aorta 

step 6

blood is disturbuted by the systemic arteries

step 7

blood enters systemic capillaries for nutrient and gas exchange

step 8

deoxygenated blood exits systemic capillaries and returns to the heart by systemic veins that ultimately drain in
