White blood cells, muller, brito p. 2013

  1. 1. White Blood Cells Lymphocytes and Phagocytes
  2. 2. The white blood cells defend us against disease. There are far fewer of them than red blood cells Structure The nucleus of the lymphocyte is larger and the nucleus of the phagocyte is lobed
  3. 3. Phagocytes Phagocytes engulf and digest waste material and bacteria. They are big cells responsible for the innate immunity: they are the first line of defence of the body, and act "by eating" the foreign bodies http://www.youtube.com/watch?v=CEOV-SFTlpY
  4. 4. Lymphocytes Lymphocyte is a smaller white blood cell that serves to fight infection along with immune responses in the body, producing antibodies -They make them stick together. -They dissolve their cell Membranes. -They neutralise the toxins. http://www.youtube.com/watch?v=cD_uAGPBfQQ
