Blood is found in which of the following areas of the heart just before it is pumped into the lungs? A. the superior vena cavaB. the left atriumC. the right atriumD. the left ventricleE. the right ventricle

Answer: E - The right ventricle.

Explanation: Deoxygenated blood with carbon dioxide and metabolic products collected from the tissues by the capillaries returns to the heart via the venous system and enters the right atrium of the heart. It is then pumped to the right ventricle, then transported to the lungs via the pulmonary artery for gaseous exchange, where oxygen is collected and carbon dioxide is dropped off.
