Capillary is a medical term used for the small and thin blood vessels in our body that carry blood from our heart to different organs and tissues. These vessels are called capillaries because they are very small, just like the size of a hair. Capillaries are very important for our body's overall health, as they provide nutrients and oxygen to different parts of our body. The use of the word "capillary" is usually limited to biology and medical contexts.
