Hello, thank you for taking some time to look at my report about capillaries . Capillaries are the smallest blood vessels in the body. They can only bee seen under a microscope.
Capillaries connect the smallest arteris with the smalest vaines.
They make up a complete network of blood vessels through all parts of the body. The largest capillaries are in the bone marrow. The smallest capillaries are in the brain and lining of the intestine. Capillaries have thin walls. Food which are carried in the blood strem are able to pass through thier walls into the tissues.
