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.
Report Abuse. The two most common kinds of tests to determine your blood type: the ABO Test and the Rhesus (or Rh) Test. The ABO Test classifies people's blood into one of four types: A, B, AB, or O. If your red blood cells have the A antigen, you have type A blood.If your red blood cells have the B antigen, you have type B blood.If you have neither the A nor B antigen, you have type O blood. Your plasma contains antibodies against both type A and type B blood. If your red blood cells have both the A and B antigens, you have type AB blood.Your plasma does not contain antibodies against either type A or type B blood.our plasma contains antibodies against both type A and type B blood. If your red blood cells have both the A and B antigens, you have type AB blood. Your plasma does not contain antibodies against either type A or type B blood.
