Transport of oxygen, carbon dioxide, water, nutrients and hormaones, defence against infection and heat regulation. 1 of 20 What is the composition of blood? plasma (the liquid fraction), erythrocytes (red blood cells), Buffy coat (white blood cells and platlets) 2 of 20 what is the % of plasma in whole bood? 55% 3 of 20 what is the % of Erythrocytes? 45% 4 of 20 what is the composition of plasma? water, blood proteins, nutrients, hormaones and electrolytes 5 of 20 what are the different types of blood cells? Erthrocytes (red blood cells), leucocyte (white blood cells), basophils, eosinophil, lymphocyte, monocyte, platelets. 6 of 20 what are platlets? small non-nucleated discs formed in the red bone marrow. 7 of 20 what do they do? functional in blood clotting 8 of 20 what are erythrocytes? They are biconcave, non-nucleated discs containing haemoglobin. 9 of 20 what is it formed by? red bone marrow 10 of 20 what is the function of erythrocytes? to transport oxygen from the lungs to tissues. 11 of 20 what is a leucocyte? they are white blood cells, they are the largest blood cell. 12 of 20 what are their function? they defend the body against microbes and other foreign materials. 13 of 20 what do they contain? nuclei, and some have granules in their cytoplasm. 14 of 20 what are the different types of leucocytes? granulocytes- (eosinophils, basophils, neutrophils) and Agranulocytes (monocytes and lympocytes) 15 of 20 what is the composision of the granulocytes ? contain multi-lobed nuclei and granules in their cytoplasm. 16 of 20 what is the composition of Agranulocytes? they contain a large nucleus and have NO granules in their cytoplasm 17 of 20 using the pictures which one is the eosinophil, basophil, neutrophil, erythrocytes, platlets, monocyte, lymphocyte? show pictures 18 of 20 why do erythrocytes have their characteristic shape? being biconcave inccreases their surface area which increases their ability for transporting oxygen. 19 of 20 what is the difference between bird and mammal erythrocytes? birds have a nuclues and are an oval shape and mammals dont have a nuclues and are a rounded shape. 20 of 20
