The blood stream or cardiovascular system is a closed circuit circulatory system which ensures that blood is carried from the heart to the body's various organs and vice versa. Blood flow enables nutrients, oxygen and hormones to be carried to the body's cells and to collect cell waste as well as regulating various factors such as blood sugar levels.
