Oxygen and Blood Circulation Machines :

• The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body.
• It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.
• The system of blood vessels resembles a tree: The “trunk”, the main artery (aorta), branches into large arteries, which ramify into smaller and smaller vessels.
• The smallest arteries end in a network of tiny vessels, the capillary network.
• There is not only one blood circulatory system in the human body, but two, which are connected
• The systemic circulations provides organs, tissues and cells with blood so that they get oxygen and other vital substances.
• The pulmonary circulation is where the fresh oxygen we breathe in enters the blood. At the same time, carbon is released from the blood.
