As men age, their prostate tends to enlarge. Which symptom could be caused by an enlarged prostate?
The testes would not maintain the proper temperature.
The flow of urge may be blocked or slowed.
Seminal fluid would not have the proper pH.
Sperm would not be allowed to fully mature.
The Correct Answer is B
A. The testes would not maintain the proper temperature: Temperature regulation of the testes is controlled by the scrotum and muscles, not the prostate.
B. The flow of urine may be blocked or slowed: Benign prostatic hyperplasia (BPH), or an enlarged prostate, can compress the urethra, leading to difficulty urinating or weak urine flow.
C. Seminal fluid would not have the proper pH: The prostate contributes fluids to semen, but BPH typically affects urine flow more than seminal fluid pH.
D. Sperm would not be allowed to fully mature: Sperm maturation occurs in the epididymis, not in the prostate.

Explanation
A. It is the air in the lungs after maximal inhalation: Total lung capacity (TLC) refers to the total amount of air the lungs can hold after maximum inhalation.
B. It is the quantity of air that a person can move into or out of the lungs: This defines vital capacity, not total lung capacity.
C. It is the amount of air that remains in the lungs after a normal tidal expiration: This describes functional residual capacity, not TLC.
D. It is the maximum volume of air that can be exhaled from the lungs after maximum inhalation: This is the definition of vital capacity (VC), not total lung capacity.
Correct Answer is A
Explanation
A. Lysozyme within tears destroy bacteria.: Lysozyme is an enzyme found in tears that helps to break down the cell walls of bacteria, acting as a chemical barrier and part of the innate immune system's first line of defense.
B. Chemotaxis attracts phagocytes to the site where the pathogen invaded.: This is part of the inflammatory response, which occurs after the first line of defense has been breached; therefore, it is not considered a first line of defense action.
C. Natural killer cells are the first lymphocytes to react to infection.: While natural killer cells play an essential role in the immune response, they are part of the second line of defense and respond after pathogens have entered the body.
D. Phagocytes ingest microbes when they enter the body.: This is part of the second line of defense, as phagocytes respond to pathogens that have breached the first line of defense, which includes physical and chemical barriers.
