On reaching organ or tissue, the artery divides into smaller and smaller vessels to bring the blood in contact with all the individual cells.

The smallest vessels have walls which are one cell thick and are called capillaries.

Exchange of material between the blood and surrounding cells takes place across this thin wall.
