Capillaries have cell walls that are onlt one cell thich to allow nutrients to pass through and into the body cells and back again. I hope this helps :-)
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
capillaries is where the exchange of materials occur such as; gases,nutrients, hormones, and so on.between the blood and the interstitial fluid.
The exchange that takes place between organs and blood are **** and ********
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
it is a large fenestrations in the endothelial cells that allow drugs to exchange freely between blood and interstitium , it is found in the Liver for example
The human circulatory system consists of arteries, veins, and capillaries. The capillaries are the thin-walled vessels that connect arteries and veins and allow for the exchange of materials between blood and tissue fluid.
capillaries
Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
materials exchange between blood cells and blood

Capillaries via osmosis
Capillaries - The endometrium (epithelial lining/wall) of the capillaries is only one cell thick optimizing diffusion/osmosis between it and the tissue cells of the body

The walls of alveoli are thin to allow the exchange of gases (Co2 and O2) between blood capillaries and the aveoli in the lungs.
