If all arterial blood is directed into the capillary bed, the flow rate of the blood in the capillaries should

Questions are based on the following passage: Capillaries are fine, branching blood vessels that connect arteriole and venule vessels. They work as networks called capillary beds and allow for fluid, nutrient, and waste exchange between the blood and body tissues. The porous capillary walls allow for diffusion of water and small solutes, while larger biomolecules like proteins cannot pass through. At the arteriole end, fluid moves from the vessel to the body tissue, while at the venule end, fluid, gas, and wastes enter the capillary from the body tissue. In the central portion of the...

Questions are based on the following passage:

Capillaries are fine, branching blood vessels that connect arteriole and venule vessels. They work as networks called capillary beds and allow for fluid, nutrient, and waste exchange between the blood and body tissues. The porous capillary walls allow for diffusion of water and small solutes, while larger biomolecules like proteins cannot pass through. At the arteriole end, fluid moves from the vessel to the body tissue, while at the venule end, fluid, gas, and wastes enter the capillary from the body tissue.

In the central portion of the capillary network, fluid passes equally between the capillary and body tissues, and general gas, nutrient, and waste exchange takes place. In particular, fluid exchange is controlled by hydrostatic and osmotic pressure.
