capillaries
capillaries
There are blood capillaries close to all of the cells in our body, so that the cells can get all of the energy they need to survive.Blood capillaries are only one cell thick, so that nutrients and oxygen can pass through them easily.
All the body cells can stay close to the capillaries for the exchange for materials with the blood
capillaries carry blood from the heart to the body
continuous capillaries
Capillaries supply blood to your tissues. When the body is at rest, less energy is being used so the capillaries are not as engorged in comparison to exercise. When one rests on harder surfaces, more pressure points occur that can close off capillaries and decrease blood flow. This can be amended with cushioning, or balanced by changing body position intermittently to allow easier circulation to these areas.

Capillaries are one-cell wide blood vessels. They allow intimate close-contact with muscle and other body cells with red blood cells. It is in capillaries that oxygen exchange occurs. In close contact with muscular myoglobin, adult hemoglobin releases its oxygen and myoglobin picks it up.
The smallest blood vessels are called capillaries. The next largest are veins. The largest are arteries. Arteries are deeper in the body than veins and capillaries, which are closer to the skin. Some veins are also deep within the body. There is no type of blood vessel starting with the letter "A" that is close to the skin.
