Blood Transport in Mammals  Lesson Objectives 1. To be to recognize components in blood and know their functions. 2. To know the function of red blood cells, and white blood cells. Why blood is red? Red Blood Cells What else in the blood? Composition of Blood How do the scientist know the component of blood? Using Microscope Blood Sample Under Microscope Blood red blood cell white blood cell platelet plasma  Where are red blood Bone marrows cells made?  NO NUCLEUS Red pigment  WHITE BLOOD CELLS Destroy microorganisms Phagocytes Lymphocytes  Phagocytes Capture the bacteria – produces enzyme – digest the bacteria Lymphocytes Plasma Blood Learning Check  Three functions of plasma Transporting Transporting blood cells Transporting waste nutrients Which part gives blood its colour? Red blood cells What is function of red blood cell? To carry oxygen What is function of white blood cell? Destroy microorganisms How are red blood cells adapted to contain as much haemoglobin as possible? No nucleus Biconcave shape Why is this useful for red blood cells? To carry more oxygen Although red blood cells carry oxygen, they do not need a supply of oxygen themselves. Why not? No mitochondria – do not need oxygen for respiration
