Last lesson I dissected a fresh specimen of a pigs heart to learn the structures within.
The heart has a left and right side, that both play vital roles in blood circulation.
Each side has two chambers; a ventricle that pumps blood out into the arteries and the atrium that collects blood from the veins.
Each side has two valves; an atrioventricular valve (between the atrium and the ventricle and the semilunar valve).
Oxygenated blood flows into the left side through the pulmonary veins (from the lungs).
Blood flows out through the aorta.
Deoxygenated blood flows into the left side (through the vena carva) and out through the pulmonary arteries.
The left side of the heart has a thicker muscle wall as it pumps blood further to the lungs, unlike the thinner right side.
