A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. complete blood type would describe a full set of 30 substances on the surface of RBCs, and an individual's blood type is one of many possible combinations of blood-group antigens.
Thus, cavitation is the name given to a mechanism in which vapor bubbles (or cavities) in a fluid grow and collapse due to local pressure fluctuations. These fluctuations can produce a low pressure, in the form of vapor pressure of the fluid.
(plural cavitations). 1  The formation of pits on a surface. ( 2 sciences) The formation, in a fluid, of vapor bubbles that rapidly collapse; especially in a rotating marine propeller or pump impeller. ( 3 biology) The formation of cavities in an organ, especially in lung tissue as a result of tuberculosis.avitation. the formation of partial vacuums within a flowing liquid as a result of mechanical force, as with a boat propeller or a pump impeller: when these collapse, pitting or other damage is caused on metal surfaces in contact.
