Capillary is a very small blood vessel. It is so small that you can't see it with your eyes. Capillaries are found all over your body, in your skin, muscles, and organs.
Blood is a liquid that carries oxygen and nutrients to your cells. It also carries away waste products from your cells. Capillaries are the smallest blood vessels in your body, and they are the places where blood exchanges oxygen and nutrients with your cells.
The walls of capillaries are very thin, which allows oxygen and nutrients to pass through the walls and into your cells. The waste products from your cells also pass through the walls of the capillaries and into the blood.
Capillaries are very important for your body. They help to keep your cells healthy and functioning properly.
Imagine that you have a big city, and the blood vessels are the roads. The capillaries are the smallest roads in the city, and they are the places where people exchange goods and services.
The goods and services in this analogy are oxygen and nutrients, and the people are your cells. The capillaries are the places where the oxygen and nutrients from the blood are exchanged with the cells.
The capillaries are the smallest blood vessels in the body.
