Explanation / Answer
Blood helps to maintain homeostasis by transporting material between tissues and external environment. The benefit of bi concave shape red blood cells is that it allows the cells to hold more haemoglobulin. Erythropoietin is the harmone stimulates red blood cells formation. Platelets - phagocytize is blood component that is not correctly matched with it's function. Erythrocytes are the blood components that do not have nuclei. As red blood cells become older they become fragile. The carrier protein that transport absorbed iron through blood is Transferrin. Platelet plug formation is initiated when platelets come into contact with collagen fibres in connective tissue beneath the endothelium. A blood cloth that forms is an undamaged vessel is called an thrombus and if it breaks loose it travels through blood stream called embolus. A pulmonary embolism is a blood clot that blocks blood flow in a vessel supplying part of lung. a person blood type is determined by mixing the blood with different antibodies to see which one cause the red blood cells to aggulitinate. There is a never risk to feutus in any pregnancy. A blood transfusion reaction will occur when plasma antibodies contact red blood cells carrying antigen with which they react. A person with type O+ blood would have Rh but not A or B antigen on his RBC s Arterioles return blood from tissues to atria. Veins contain valves but arteries do not. The pulmonary circulation carries blood from right ventricle to lungs and back to left atrium. Carbon dioxide, oxygen. Brachial artery is found in arm
