The system is necessary to provide the body with oxygen and various nutrients. Also, the blood takes carbon dioxide, which is produced during the vital activity of cells, and removes it through the capillaries in the lungs back into the atmosphere. In case of cessation of blood circulation, the death of the body occurs.
