1. Which action is a purpose of the inflammatory process?
a. To provide specific responses toward antigens
b. To lyse cell membranes of microorganisms
c. To prevent infection of the injured tissue
d. To create immunity against subsequent tissue injury
ANS: C
If the epithelial barrier is damaged, then a highly efficient local and systemic response (inflammation)
is mobilized to limit the extent of damage, to protect against infection, and to initiate the repair of
damaged tissue. The response to a specific offending agent is the function of the adaptive immune
response. Lysosomes lyse cell membranes. Immunity against a subsequent tissue injury occurs
through the action of B cells and T cells.

2. How do surfactant proteins A through D provide innate resistance?
a. Initiate the complement cascade.
b. Promote phagocytosis.
c. Secrete mucus.
d. Synthesize lysosomes.
ANS: B
The lung produces and secretes a family of glycoproteins, collectins, which includes surfactant
proteins A through D and mannose-binding lectin. Collectin binding facilitates macrophages to
recognize the microorganism, enhancing macrophage attachment, phagocytosis, and killing. The
complement cascade occurs during the inflammatory phase. These proteins do not secrete mucus of
synthesize lysosomes.

3. Which secretion is a first line of defense against pathogen invasion that involves antibacterial and
antifungal fatty acids, as well as lactic acid?
a. Optic tears
b. Oral saliva
c. Sweat gland perspiration
d. Sebaceous gland sebum
ANS: D
Sebaceous glands in the skin secrete sebum that is made up of antibacterial and antifungal fatty acids
and lactic acid that provide the first-line barrier against pathogen invasion. Perspiration, tears, and
saliva contain an enzyme (lysozyme) that attacks the cell walls of gram-positive bacteria.

4. Which bacterium grows in the intestines after prolonged antibiotic therapy?
a. Lactobacillus
b. Candida albicans
