Topics included in this book: Blood flow through arteries, where the investigations of blood flow through arteries are of considerable importance in many cardiovascular diseases particularly atherosclerosis. Blood flow under normal physiologic conditions is an important field of study, as is blood flow under diseased conditions. Properties of blood, where, the study of the rheological properties of blood can allow a better understanding of blood circulation. Blood Visco-elasticity, where, Blood Visco-elasticity is a property of human blood that is primarily due to the elastic energy that is stored in the deformation of red blood cells as the heart pumps the blood through the body. There were only minor differences between adult and pediatric blood, which allows the same blood analog to be used in both cases. The pulsatile flow of blood, where, the pulsatile flow of blood through an artery has great importance in medical sciences. The properties of human blood as well as blood vessels and magnetic field effect were the subjects of interest for several researchers.
