![]() ![]() Normal adult blood viscosity is 40/100 (forty over one hundred) the Unit is millipoise, symbol: mP, SI unit for dynamic viscosity is the Pascal second and 1pascal second is equal to 10000 millipoise. This is mathematically expressed by the following equation:īlood viscosity: is the resistance of blood to flow. Because of this, the velocity of blood flow across each level of the circulatory system is primarily determined by the total cross-sectional area of that level. In a normal circulatory system, the volume of blood returning to the heart each minute is approximately equal to the volume that is pumped out each minute (the cardiac output). Blood then returns to the left side of the heart where it begins the process again. The venous system returns the de-oxygenated blood to the right heart where it is pumped into the lungs to become oxygenated and CO2 and other gaseous wastes exchanged and expelled during breathing. The other-circulation - the arterioles, capillaries, and venules -constitutes most of the area of the vascular system and is the site of the transfer of O2, glucose, and enzyme substrates into the cells. The capillaries connect to venues, and the blood then travels back through the network of veins to the right heart. It then divide into smaller and smaller arteries, then into arterioles, and eventually capillaries, where oxygen transfer. The rate of blood flow out of the heart (often expressed in L/min) is known as the cardiac output (CO).Īverage density: 1.05 g/cm3 Composition: 40-45 % corpuscular, 55-60 % plasmaBlood pumped out of the heart to the aorta. Blood: liquid connective tissue made up of red blood cells(Erythrocytes), white blood cells(Leukocytes), platelets liquid plasma,it transport protein, hormones, oxygen, carbondioxid, nutrients, cellular waste products. Capillaries: very small and thin vessels carry from Arteries to Veins. Veins(Venules): thin vessels carry the blood to the Heart. Arteries(Arterioles): thick vessels carry the blood away from the Heart. Blood flow is circulation of Blood in the Blood circulatory system (cardiovascular system). ![]()
