23+ Blood Flow Through The Heart Anatomy And Physiology. Blood flow through the heart: Right atrium → right ventricle → left atrium → left ventricle → and repeat ad nauseum.
Four valves ensure unidirectional blood flow through the chambers of the heart the left ventricle pumps this blood through the aortic semilunar valve and into the aorta.
The heart has two types of valves that keep the blood flowing in the correct direction. The heart is a muscular organ about the size of a closed fist that functions as the body's circulatory pump. I really enjoy reading these anatomy and physiology excerpts! Blood returning from the lungs enters the left atrium through the four pulmonary veins (figure 12.10).
