      Blood is the body’s internal transportation system. Pumped by the heart, blood travels through a network of blood vessels, carrying nutrients (O2, glucose) and hormones tothe cells and removing waste products (CO2. urea) fromthe 1012(= 100 trillion) cells of our bodies.. THE HEART 1. The central organ of the cardiovascular system is the heart.

      Blood is the connecting link between the outside environment and the internal environment of the cells in our body. To maintain homeostasis throughout the body (see Homeodynamics), blood must flow continuously with various velocities adapted to the actual needs of the cells.

      In just under thirty seconds, your blood moves (circulates) through your entire body. It reaches every one of your trillions of cells. Blood carries things to each cell that are needed. These things include oxygen and nutrients. In exchange, the blood picks up waste from the cells, including carbon dioxide, heat and excess water.

      Typically, the blood volume in the human fetus is 10 to12% of the body weight compared to 7 to 8% in adults(Brace, 1993). One of the reasons for this differenceis that the placenta contains a large pool of blood,a volume that is gradually reduced with the progressof gestation (Barcroft, 1946) (Figure 1).
