17. What type of immunity does inhaling a virus produce active natural 1 mark
18. What type of immunity does breast feeding produce passive natural 1 mark
19. B cells are converted to T cells in which organ beginning with T thymus 1 mark
20. B cells provide what form of immunity hint: like the pencil humoral 1 mark
21. T cells provide what form of immunity: hint HIV depresses these cells bursal 1 mark
22. The thymus is anterior to which circulatory organ heart 1 mark
23. Explain why the immune system is so important to the human being 3 marks
  The immune system protects the body against pathogens that may enter the body, either bacterial, viral or fungal, it provides the ability to produce chemicals that destroy or enlist other body cells to aid in the defence of the body  
24. Explain why the body needs a series of vessels to drain lymph fluid 3 marks
  3 litres of fluid is forced out by blood hydrostatic pressure and remains in the tissue and cannot be reabsorbed back into the bloodstream, the lymphatic vessels have simple squamous cells with loose junctions between cells that enable the fluid to be quickly reabsorbed into the lymph vessels for transport up the body into the venous blood vessels thus maintaining blood volume and preventing tissue oedema  
25. What nutrients are the lacteals involved in absorbing and where are they located 3 marks
  Lacteals are located in the small intestine they are formed from projections of the epithelium into fingers lined with cells, lacteal (lymph capillaries) are blind ended vessels that drain fat and other nutrients from the intestine which turns the normally clear lymph fluid a white colour.
