Lecture 2 Flashcards
What are antigens?
the shapes that the immune system recognizes
What 3 factors make up innate immunity?
Physical barriers (i.e. skin) Phagocytic Cells (neutrophils) The Complement System
What actions do the complement proteins make to limit infections?
Vasodilation to improve access for neutrophils
Chemotaxis to attract neutrophils
Coating the material to make it easier to phagocytose
Lysing bacterial cell walls
What is oponization?
When complement proteins coat a foreign material to aid phagocytosis
What is the most common class of soluble immune receptors?
Antibodies
What are the basic steps in an immune response?
Activation of specific antibodies and cytotoxic lymphocytes and production of immunological memory to allow a more rapid and effective response if there is a second infection
What is acquired immunological tolerance?
when the immune system recognises a shape as self and therefore does not attack it, this training happens in utero
What is autopoiesis?
Self generation
What two processes could the conservation of be described as living?
Autopoiesis and adaptation
Besides fighting disease what is one other function of the immune system?
Aiding in recovery from tissue damage
What does humoral mean?
To do with bodily fluids
