Absorption is the process by which nutrients are moved into lymph and blood.
The walls of capillaries are very thin allowing the nutrients of cells to diffuse through them. They facilitate the diffusion of nutrients to the body by passing them through their cell walls.
The capillaries found in the alveoli, nephrons, and vili are thin-walled and narrow. This size and construction makes it easier for nutrients, oxygen, and wastes to diffuse from body tissues.
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
The oxygen and other nutrients in the blood diffuse into the cells through osmosis, and then wastes and other harmful chemicals are diffused out.
Nutrients and oxygen diffuse through the capillaries, due to diffusion.
The capillaries are one celled blood vessels with no real walls. It is primarily used to diffuse nutrients and gas through. It is known to be the most functional unit of the blood vessels.
O2 would diffuse into the cells, and CO2 would diffuse into the systemic capillaries.
the capillaries diffuse the digested food to every cell in the body
Most absorption of nutrients occurs in the small intestine. And as far as digestion itself, it would be after the food particles are small enough to diffuse through the blood capillaries.

Most nutrients are just dissolved in the plasma of the blood. They are transported to the cells when the heart pumps the blood through arteries, arterioles and capillaries. Nutrients diffuse through the walls of capillaries and enter cells.
