What does Blood actually do?


Red blood corpuscles passing through a small vein. Every day, the tiny red blood corpuscles travel a distance of about 15km.

 Blood is made up of three cell types and plasma which together have several vital tasks to perform. On the one hand, blood is a means of transport, supplying every part of the body with oxygen and nutrients. On the other it removes carbon dioxide and waste products. In addition to these functions, it serves as a means of communication between different organs by carrying hormones and other chemical messengers from place to place. The constant circulation of blood also helps to keep our body's temperature constant, and blood platelets help to protect us by blocking the flow of blood from wounds. The red corpuscles contain hemoglobin, a molecule that transports oxygen around the body, while the various types of white corpuscles play an important role in our body's vital immune defenses. They are constantly patrolling the whole body and are able to penetrate into any type of tissue through the blood vessel walls and remove foreign matter, harmful bacteria and diseased cells.
