THE FOUR MAIN COMPONENTS OF BLOOD Click on the pictures to learn about their functions. White blood cell • • Red blood cell Defends against diseases Haemoglobin transports Kills microbes in the body oxygen to cells in the body. FOUR MAIN COMPONENTS OF BLOOD Platelets Plasma Liquid component of the blood Clot the blood which then which regulates heat transfer prevents further bleeding inside and also transports CO 2, soluble and at the surface of the body. food, urea and hormones.
STRUCTURE OF RED BLOOD CELLS Click on the boxes below to learn more. DESCRIPTION OF CELL It has a biconcave shape (depression in the middle on both sides) which increases the surface area available to absorb oxygen. HOW TO ILLUSTRATE ON PAPER Top view It is the only cell in the body which doesn’t contain a nucleus. This give more room in the cytoplasm to transport more haemoglobin.
