Question | Answer |
Describe platelets | -thrombocytes -cell fragments -initiate blood clotting -smallest formed elements found in the blood -hemostasis |
Describe red blood cells | -erythrocytes -transport O2 and CO2 -most numerous circulating blood cells -during erythropoiesis they decrease in size -shaped in biconcave disks -develop Hb/Hgb (gives them their red colour) -Hb carries O2 to body tissue 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 -protect upper respiratory structures -acts as filters |
Describe white blood cells | -protect the body from pathogens -remove debris from injured tissue -aid in healing process -diapedesis -initial inflammation & immune response -phagocytic -some granulocytes, some agranulocytes -migrate through capillaries & venules |
List autoimmune diseases | -Myasthenia gravis -rheumatoid arthritis -systemic lupus erythematosus -AIDS -allergies -thrombocytopenia -vasculitis |
