Lines of defense
Specific-Immunity
Often occurs alongside nonspecific reactions, such as inflammation or if an infection persists.
Non-specific Immunity
React to any kind of damage, such as physical knock a burn, extreme cold, corrosive chemicals, and living invaders.
-
Second Line of Defence
Activated if invaders that take up residence within the body. Non-specific defence mechanisms that relies on phagocytosis via macrophage and Inflammation
-
-
Temperature
When you are infected with a cold or flu, macrophages will destroy the microbes and release chemicals into the blood. When these chemicals are detected by the hypothalamus (brain), they cause an increase in bodies temperature aka fever. The higher temperature helps prevent the spread (reproduction) of the microbe.
Third Line of Defence
There are two main types of specific immunity: Cell-mediated Immunity and antibody-mediated Immunity.
Cell-mediated Immunity- activation of phagocytes, T cells and the release of various chemicals in response to a foreign antigen.
-
T Cells
there are four different types of T cells they Helper T cells, Killer T cell, Suppressor T cells, and Memory T cells.
