MICROANATOMY

Detailed explanation-1: -Capillaries are thin-walled vessels composed of a single endothelial layer. Because of the thin walls of the capillary, the exchange of nutrients and metabolites occurs primarily via diffusion. The arteriolar lumen regulates the flow of blood through the capillaries.

Detailed explanation-2: -Oxygen, carbon dioxide, nutrients, and wastes are exchanged through the thin walls of the capillaries.

Detailed explanation-3: -Capillaries allow the exchange of gasses, nutrients, hormones, and other molecules in the blood. These materials are exchanged with the cells of the body. Carbon dioxide and waste are transferred from the body to the capillaries. Capillaries exchange material with the extracellular fluid.

Detailed explanation-4: -Capillaries are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide and waste products to pass to and from the tissue cells.

Detailed explanation-5: -capillaries-these are tiny vessels that connect arteries and veins. Their thin walls allow blood to come into close contact with tissues to exchange oxygen, carbon dioxide, nutrients and waste products.
