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.
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.
If a patient has cirrhosis of the liver and is unable to produce sufficient albumin and other plasma proteins, then what variable is changed in capillary exchange, and what is the effect?
a. There is no change in the capillary exchange process.
b. Hydrostatic pressure in the blood decreases, and fluid remains in the blood.
c. Colloid osmotic pressure in the capillary increases, and blood volume increases in the blood vessels.
d. Colloid osmotic pressure in the capillary decreases, and fluid remains in the interstitial fluid, potentially causing edema.
