Answer:
de-oxygenated blood from the whole body enters the right atrium through the superior and inferior venae cavae (plural)
the right atrium contracts and blood flows into the right ventricle.
From here the blood is pumped into the pulmonary arch.
the pulmonary arch divides into 2 pulmonary arteries leading to each lung.
gas exchange takes place in the lungs
than the oxygenated blood comes back to the left atrium by the pulmonary veins.
the blood moves from the left atrium to the left ventricle.
from the left ventricle it is pumped into a large artery named aorta.
the aorta supplies blood to the whole body.
two small coronary arteries emerge from the aorta and supply blood to the heart muscles.
veins carry de-oxygenated blood, except the pulmonary vein.
Arteries carry oxygenated blood, except the pulmonary artery.
capillaries supply blood to cells. They are found between the cells of all tissues.
illiac artery supplies blood to the hind limbs
renal artery supplies blood to the kidneys.
hepatic artery supplies blood to the liver
femoral artery supplies blood to the legs.
carotid artery supplies blood to the neck and face.
clavicle artery supplies blood to the arms.
mesenteric artery supplies blood to the organs of digestive system.
