The capillaries are branches of venules or arterioles and walls of the capillaries consists of a single cell layer. As they spread among the cells the nutrients and gases in blood diffuse into the cells and the waste matter in the cells diffuse into the blood capillaries.

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: -What are capillaries? Capillaries are delicate blood vessels that exist throughout your body. They transport blood, nutrients and oxygen to cells in your organs and body systems. Capillaries are the smallest blood vessels in your vascular system.
Detailed explanation-3: -Capillaries are where oxygen and nutrients are exchanged for carbon dioxide and waste. Venules: Veins begin as tiny vessels called venules and get gradually larger as they near your heart. Venules receive blood from capillaries.
Detailed explanation-4: -essentially between the arteries and the veins.
Detailed explanation-5: -A blood vessel is a tube that carries blood. Oxygen rich blood leaves the left side of the heart and enters the aorta. The aorta branches into arteries, which eventually branch into smaller arterioles. Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries.
