Chapter 42, Problem 3TYK
Summary Introduction
The circulatory system is responsible for distributing the nutrients throughout the body. In humans, the circulatory system is called a double circulatory system, since the blood passes through the heart twice per circulation. The three main components of the circulatory system are blood vessels, blood, and the heart.

Which of the following is the best description of what happens in capillaries?
A. Capillaries are surrounded by thicker smooth muscle moving blood cells to exchange nutrients and oxygen.
B. Capillaries connect minor veins to major veins returning blood to the heart.
C. Capillaries are the location where oxygen, carbon dioxide, and nutrients are exchanged with tissues at the cellular level.
D. Capillaries are the site where blood mixes with interstitial fluid to allow for gas and nutrient exchange.
A major advantage of a double circulation is thata. blood can be pumped to the upper portions of the body by onecircuit and to the lower portions of the body by the other circuit.b. each circuit can pump blood at a different pressure to optimize thefunction of each.c. the oxygenated blood can mix with the deoxygenated blood beforebeing pumped to the tissues of the body.d. less energy is required to provide nutrients and oxygen to the tissuesof the body.e. All of the above are advantages of a double circulation.
Which of the following statements about the circulatory system is false?
A. Blood in the aorta is oxygenated.
B. Blood in the pulmonary artery is deoxygenated.
C. Blood in the inferior vena cava is deoxygenated.
D. Blood in the pulmonary vein is deoxygenated.
