4 MAIN COMPONENTS OF THE BLOOD Click on the pictures to learn about their functions THE BLOOD 4 MAIN COMPONENTS • White blood cell • Defends against diseases • Kills microbes in the body • Plasma • Liquid component of the blood which transports: • CO2 • Soluble food • e.e. glucose & • amino acids • Urea • Hormones • Heat transfer • Platelets • Clot the blood which then prevents further bleeding inside and at the surface of the body • Red blood cell • Haemoglobin transports oxygen to cells in the body
STRUCTURE OF RED BLOOD CELLS Click on any one of the boxes below to learn more… HOW TO ILLUSTRATE ON PAPER DESCRIPTION OF CELL Top view It has a biconcave shape (depression in the middle on both sides) which increases the surface area available to absorb oxygen. It is the only cell in the body which doesn’t contain a nucleus. This give more room in the cytoplasm to transport morehaemoglobin. Cell membrane Side view IMAGE - MICROSCOPE Cytoplasm WHITE BLOOD CELL
STRUCTURE OF WHITE BLOOD CELL Click on any one of the boxes below to learn more… HOW TO ILLUSTRATE ON PAPER DESCRIPTION OF CELL Top view It has an irregular shape and contains a noticeably large nucleus. Nucleus Cell membrane IMAGE - MICROSCOPE Cytoplasm RED BLOOD CELL
STRUCTURE OF BLOOD MISCONCEPTIONS Click on the speech boxes which you consider to be CORRECT. 4) The shape of red blood cell are biconcave so that the surface area is increased so that more oxygen is absorbed 4) The shape of red blood cells are biconcave so that more can fit into blood vessels 3) The size of platelets are much smaller than the size of red blood cells 1) Red blood cells transport oxygen while the plasma transports CO2 3) The sizes of platelets and red blood cells are similar 1) Red blood cells transport oxygen to the lungs and CO2 from the cells. 2) There is only one type of white blood cell namely a phagocyte 5) Only white blood cells can fight infection 2) There are 2 types of white blood cells namely phagocytes and lymphocytes 5) Red and white blood cells can fight infection
