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.
Learn actively all the features of this organ and cement them long term by testing yourself using kenhub's. Oxygenated blood is carried to the heart from the lungs in the pulmonary vein. As blood flows from the atria to the ventricles, it passes through the tricuspid and bicuspid valves, also known as the atrial ventricular or av valves.
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).
