Question

Which answer choice accurately depicts the sequence by which blood moves from the pulmonary vein to the body tissues?

Answer 1

Answer:

See the answer below

Explanation:

Oxygen-rich blood flows from the lung through the pulmonary vein to the left atrium of the heart. From there, the blood is pumped through the mitral valve to the left ventricle. The contraction of the left side of the heart sends the oxygenated blood out of the left ventricle through the aortic arch to the major arteries designated to carry blood to the major parts of the body. From the arteries, blood moves to the capillaries and then to the various tissues of the body before returning back to the heart through the vein.

Thus, the sequence of flow of blood from the pulmonary vein to the body tissues can be summarized as:

Pulmonary vein -> Left atrium -> Arteries -> Capillaries -> tissues
