What factor can increase blood pressure?
An increase in parasympathetic stimulation
A decrease in peripheral resistance
An increase in heart rate
A decrease in stroke volume
The Correct Answer is C
A. An increase in parasympathetic stimulation: Parasympathetic activity lowers heart rate and typically reduces BP, so this would not increase BP.
B. A decrease in peripheral resistance: Lower peripheral resistance reduces BP (BP = CO × PR), so this would decrease BP.
C. An increase in heart rate: Raises cardiac output (if stroke volume is similar), which tends to increase blood pressure.
D. A decrease in stroke volume: Lowers cardiac output and therefore tends to decrease BP.

Correct Answer is A
Explanation
A. To produce antibody molecules: plasma cells are differentiated B cells specialized for synthesizing and secreting antibodies.
B. To directly attack cells displaying antigens: cytotoxic T lymphocytes (and NK cells) directly attack antigen-bearing cells; plasma cells primarily secrete antibodies.
C. To increase the volume of the blood plasma: plasma cell activity does not change plasma volume; they produce proteins (antibodies), not fluid volume.
D. To produce interferon: many cell types secrete interferons in response to viral infection (e.g., infected cells, immune cells), but plasma cells are dedicated antibody producers.
Correct Answer is D
