  • What are the components found in blood?

    Plasma, Erythrocytes (RBCs), Leucocytes (WBCs), and platelets.

  • What is the function of plasma? What does it contain?

    Transportation of nutrients and waste products. Contains water, proteins, hormones, urea, glucose, and carbon dioxide.

  • What is the function of red blood cells (erythrocytes)? What do they contain?

    Transport oxygen. They have a large surface area/cncave shape and contain haemoglobin which binds to oxygen.

  • What is the function of white blood cells (leucocytes)? What do they consist of?

    Defence against pathogens. They consist of phagocytes and lymphocytes.

  • What is the function of platelets? How are they formed?

    Aid in blood clotting. They are formed from larger cells in the liver.

  • How do blood clots work?

    When a blood vessel is ruptured, platelets bind to the site of the wound and attach with a protein called fibrinogen (soluble in blood plasma) and changes shape and becomes fibrin (NOT soluble in blood plasma). Fibrin forms a net which traps more platelets and red blood cells, causing the area to become thick and stop flowing.

  • Why is blood clotting essential?

    Without blood clotting, an animal would bleed to death even after a minor wound. It also helps to prevent infection by pathogens which would otherwise enter the circulatory system through the open wound.
