| Summary: | Mathematical model of human blood circulaion gives the relation between pressure, volume and blood ‡ow. The mathematical model obtained is in the form of algebraic system of equations for a systemic circulation (heart- <br />
<br />
<br />
tissues-heart) and pulmonary circulation (heart-lungs-heart). The parameters that appear are parameters related to the nature of blood vessels: arteries and veins that are elastic, and capillary that is rigid. By considering the control mechanisms that occur in the blood circulation, namely baroreceptor loop and autoregulation, we could get mathematical model that relevan to the real blood circulation which is called controlled circulation model with autoregulation. Mathematical model of blood ‡ow in fetus on the mother’s <br />
<br />
<br />
uterus is different from adult human blood ‡ow model. That is because fetal lungs is not functioning yet. On fetal heart there are additional connections, that are ductus arteriosus and foramen ovale that shunt blood ‡ow away from lungs. So that blood ‡ow in fetal lungs close to zero, whereas blood ‡ow in the tissue close to two times the blood ‡ow to the heart. This model also may <br />
<br />
<br />
explain the mechanism of changes in blood ‡ow (the closed of ductus arteriosus and foramen ovale) as the baby is born and take the …rst breath. |
