A 12-year-old boy was bitten by a dog, and inflammation took place at the site of the injury. During the process of opsonization, what physiological event occurred?
 
  A) The boy's blood vessels dilated, allowing rapid peripheral blood flow.
  B) Viscosity of the boy's blood decreased, facilitating the migration of neutrophils.
  C) Antigens were coated, marking them for phagocytosis.
  D) T cells were released from the boy's thymus gland.

Question 2

An infant is born to an HIV/AIDS-positive mother. What treatment is provided for the infant?
 
  A) Zidovudine for 2 weeks after delivery
  B) Zidovudine for 4 weeks after delivery

Answer to Question 1

C
Feedback:
The third stage of inflammation involves opsonization, which facilitates phagocytosis. During opsonization, a substance coats the foreign antigens, producing inflammation. This inflammation makes the antigens more susceptible to the macrophages and leukocytes, thus increasing phagocytic activity. Opsonization is not characterized by T-cell activity or changes in blood flow and viscosity.

Answer to Question 2

C
