Question | Answer |
Describe platelets | -thrombocytes -smallest formed elements found in the blood -not true cells; fragments of cells -initiate blood clotting -hemostasis |
Describe red blood cells | -shaped like a biconcave disks -transports O2 and CO2 -most numerous circulating blood cells -during erythropoiesis they decrease in size -develop Hb/Hgb (gives them their red colour) -Hb/Hgb carries O2 to body tissues and exchanges it for CO2 |
Describe the spleen | -acts as a filter -resembles a lymph node -destroys old RBCs -stores healthy blood cells |
Describe the thymus | -responsible for cellular immunity -transforms lymphocytes into T cells -located in the mediastinum |
Describe the tonsils | -masses of lymphatic tissue (palatine) located in the pharynx -acts as a filter -protect upper respiratory structures |
Describe white blood cells | -protect body from pathogens -remove debris from injured tissue -aid in healing process -diapedesis -phagocytic -initiate inflammation and immune response -granulocytes (granules) agranulocyte (without granule) -migrate through capillaries & venules |
List autoimmune diseases | -AIDS -Allergies -Myasthenia Gravis -Rheumatoid Arthritis -Thrombocytopenia -Vasculitis -Systemic lupus erthematosus |
What is the function of histamines? | -initiate the inflammatory process by increasing blood flow |
What are the two ducts of the lymph system? | -right lymphatic duct -thoracic duct |
What are the four types of T cells? | -cytotoxic -helper -suppressor -memory |
What are the functions of the lymph system? | -maintain fluid balance -transport lipids away from the GI system -filter and remove unwanted infectious products |
