The velocity of blood flow, according to the equation of continuity, is: Select one: a. Independent from cross-sectional area of blood vessels. b. Directly proportional to blood viscosity. c. Directly proportional to cross-sectional area of blood vessels. d. Inversely proportional to cross-sectional area of blood vessels.

Blood velocity through capillaries is slow because a. much blood volume is lost from the capillaries. b. the pressure in venules is high. c. the total cross-sectional area of capillaries is larger than that of arterioles. d. the osmotic pressure in capillaries is very high. e. erythrocytes must pass through in single file.
Blood flow through capillaries is slow because a. lots of blood volume is lost from the capillaries. $b$. the pressure in venules is high. $c$. the total cross-sectional area of capillaries is larger than that of arterioles. $d$. the osmotic pressure in capillaries is very high. $e .$ red blood cells are bigger than capillaries and must squeeze through.
