What is blood physiology?
physiology comes from the Latin word physiology , which means "natural science". Physiology is a subset of the area of biology in which the functions of living organisms and/or their parts are studied. Blood physiology is therefore a study of functions and processes involving blood. The study also pays attention to the composition of blood, its dysfunction and other types of problems.
Blood physiology shows that blood has a number of functions in the human body. Two key functions supply oxygen and nutrients to the tissues on the one hand and remove waste products on the other. In addition. Blood transports hormones, for example, between organs and tissues. It also helps in the transfer of heat to the skin and acts as a buffer to protect the pH of the body to maintain homeostasis. Understanding blood physiology depends on the understanding of blood components. Blood consists of plasma, which represents 55% of its volume, and cellular elements that make up other 45%. These elements include red blood cells, white blood cells and plates.
plasma has four main components. It is 90% water, but also contains soluble proteins - for example albumin, globulin and protein clotting, electrolytes and elements. Albumins produced by the liver contribute to colloidal osmotic pressure and contribute to the transport of materials such as vitamins, penicillin, fatty acids and bilirubin. There are three categories of globulins - alpha, beta and gamma - of which the immune system is played. Plasma as a whole carries carbon dioxide and oxygen, breathing gases.
Red blood cells or erythrocytes (RBC) are the main transporters of oxygen and also allow carbon dioxide to be removed. White -blooded cells or leukocytes (WBC) are important in allergic reactions, killing parasites and responding to infection. Plates or platelets are fragments of cells and are essential in blood clotting.
Other important aspects of blood physiology are Blood groups ABO and Rhesus (RH Factor) factor. ABO and RH Factor Group are concernedThe antigens that characterize the blood of the individual in such a way that it can be determined whether blood transfusion is safe from one individual to another. However, this is not the only antigens - there are more than 400 different antigens of blood groups.
