Network Of Capillaries In The Human Body

“Did you know that the network of capillaries in the human body is about 50,000 to 60,000 miles long?” The circulatory system is formed with two major organs, the heart and the blood vessels, which includes arteries, veins, and capillaries. The capillaries are the thinnest type of blood vessel in the body but are one of the most important in the circulatory system. There are three major different types of capillaries: continuous, fenestrated, and discontinuous or sinusoid. The reason there are three different types is because they are all found in different areas in the human body; continuous capillaries are found in the lungs, muscle, fat, and central nervous system. Fenestrated capillaries are found the kidneys, endocrine glands and intestines. The discontinuous capillaries are mainly found in the liver, but are also found in the spleen and bone marrow.
