HUMB1000 Lecture Notes - Lecture 31: Fluid Balance, Lymphatic Vessel, Tetrafluoromethane
Document Summary
Immunity: ability to resist damage from foreign substances and internal threats, can distinguish between "self" and "non-self" Adaptive or specific immunity: innate and adaptive immunity are fully integrated in the body. Lymphatic system: transport system for cells of the immune system and antigens to move around the body, tissues where cells of the immune system "hang out" Immune system: collection of proteins, cells, tissues, and organs widely distributed throughout the body. Innate immune system: non-specific defence, present at birth, each time body is exposed to a substance, response is the same (i. e. , has no memory, provides immediate protection from pathogens and antigens, first line of defence are external features. Physical barriers: second line of defence. Physical barriers prevent entry or remove microbes. Cilia in respiratory tract, coughing, and sneezing.
