Peritonitis is an inflammation of the peritoneum, the tissue that lines the inner wall of the abdomen and covers and supports most of your abdominal organs. Peritonitis is usually caused by infection from bacteria or fungi.
Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. 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.ome of these antigens are also present on the surface of other types of cells of various tissues. Several of these red blood cell surface antigens can stem from one allele (or an alternative version of a gene) and collectively form a blood group system.
More than just two blood types are not compatible with each other. The four basic types of blood are: A, B, AB, O(not counting Rh).Type A blood can only receive blood from type A and type O. However, type A blood can donate their blood to type A and type AB. Because if a person needs a blood transfer, it MUST be from a donor with a compatible blood type. Otherwise, the transfer will kill the recipient. More elaborately, bl â¦ ood types are determined by the presence of two types of compounds in the blood.
