TRUE OR FALSE FOURTH SET (OF 5)

72. CD8 cells and natural killer cells use granzymes and perforins to kill altered cells

73 Interleukin 2 is involved in many aspects of the CMI, including activation of B lymphocytes

74 Plasma cells can produce millions of circulating antibodies an hour

75. Toxins can be removed by precipitation by antibodies and are then eaten by eosinophils

T 78.The total lung capacity for men is about 1,200 ml greater than that of women, mainly due to the greater exspiratory reserve .???

79 T lymphocytes. microglia and natural killer cells wander between blood and lymphatic tissue

80 Intussuscepsion , fistula and ileus are all potential development problems with digestive tract

Answer 1

72. True , CD8 cells and natural killer cells use granzymes and perforins to kill altered cells.

73. False , The main function of IL-2 is to promote the development of T regulatory cells. Based primarily on vitro studies, interleukin (IL)-2 has been considered a key growth and death factor for antigen-activated T lymphocytes.

74. True , the plasma cells produce large quantities ,upto 100millions of antibiotics per hour

78. False , Females' reduced airways diameter and lung volume result in lower peak expiratory flow and vital capacity. The most important consequence is women have a smaller maximal flow–volume loop.
