This allows the system to play an important role in the moving of both nutrients and wastes in and out of the blood to maintain an overall homeostasis within the body. The previously completed experiments each had the objective of understanding how various factors may have an influence on blood flow rate. These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as the effect of blood vessel length‚ and the effect

using its lungs. Increased level of pO2 causes spasm of the umbilical arteries and‚ as follows‚ decreased venous return to the right atrium. The vascular resistance in the lungs drops and all cardiac output flows through the pulmonary vessels now. Increased return to the heart through the pulmonary veins causes the raised pressure in the left atrium. As result of the changes described above foramen ovale is closed because the pressure in the left atrium becomes higher than in the right atrium. So‚ the
