  • The classical pathway
  • Eosinophils
  • Redness, heat, edema, pain
Inflammatory mediators such as bradykinin and histamine cause blood vessels to _____.
  • Vasodilate
  • Eosinophils
  • Sulfonamide
  • Mast cells
Diapedesis is
  • The microbe would survive inside the phagocyte.
  • 1. Adherence2. Chemotaxis 3. Fusion4. Ingestion5. Killing6. Elimination (exocytosis)
  • The migration of phagocytes through blood vessels to the site of tissue damage.
  • The ingestion of solid material by a eukaryotic cell
Antibodies from cellular immune responses are used in
  • The classical pathway
  • C3a, C5a, and C5bC6C7
  • They allow capillary walls to open and become leaky.
  • Alternative pathway
Pus is comprised of
  • dead phagocytes.
  • Mast cells
  • The classical pathway
  • C3a, C5a, and C5bC6C7
Which of the complement pathways was discovered first?
  • The classical pathway
  • Sulfonamide
  • Alternative pathway
  • Redness, heat, edema, pain
Why is vasodilation important to tissue repair?
  • It allows for an increased delivery of oxygen, nutrients, and phagocytes to the site of damage.
  • They allow capillary walls to open and become leaky.
  • Protozoan phagocytosis is used for feeding; phagocytosis by immune cells is used to fight infection.
  • Cells from damaged tissues and the complement pathway
In the classical pathway, which of the following directly activates cellular responses?

Which of the complement pathways employs properdin?
  • Sulfonamide

How is phagocytosis in the immune system different from protozoan phagocytosis?
  • It allows for an increased delivery of oxygen, nutrients, and phagocytes to the site of damage.
  • Protozoan phagocytosis is used for feeding; phagocytosis by immune cells is used to fight infection.
  • They allow capillary walls to open and become leaky.
  • Develops quickly, ends quickly, and is typically beneficia
