- 1MACROPHAGEWhite blood cells called monocytes travel in the blood. Once they settle in organs they develop into macrophages. These initiate the immune response displaying antigens for recognition by lymphocytes
- 2AGGLUTINOGENAntigen carried on the external surface of the membrane of red blood cells
- 3ANTIGENA molecule that stimulates an immune response by lymphocytes
- 4ANTIBODYA protein made by lymphocytes in response to the appropriate antigen
- 5AGGLUTINOGENThe clumping of red blood cells
- 6MYOGENICThe heartbeat is initiated from within the muscle itself and not due to nerve stimulation
- 7SYSTOLEStage in which the heart muscle contracts
- 8DIASTOLEStage in which the heart muscle relaxes
- 9STROKEDamage to the brain caused by a blood clot carried in the blood getting stuck in an artery supplying blood to the brain
- 10MYOCARDIAL INFARCTIONWhen blood is prevented from passing through the coronary artery to the heart muscle it supplies
- 11ARRHYTHMIAA deviation or disturbance of the normal heart rhythm
- 12AFFINITYOne molecule having a chemical attraction for another
- 13PARTIAL PRESSURE (of oxygen) (pO2)Normal atmospheric pressure is 100 kPa. As oxygen makes up 21% of the atmosphere its maximum partial pressure is 21 kPa
- 14BOHR EFFECTRelationship between the saturation of haemoglobin and the partial pressure of oxygen. The higher the partial pressure of carbon dioxide the more the curve shifts to the right
- 15TISSUE FLUIDPlasma minus plasma proteins
- 16LYMPHA colourless fluid, derived from tissue fluid, found in the lymphatic system
- 17LYMPHATIC SYSTEMA network of conduits called lymphatic vessels that carry lymph uni-directionally towards the heart
