a fall in blood pressure detected by baroreceptors initiates the cardioaccelerator reflex, which results in ______.
decreased cardiac output
increased cardiac output
increased parasympathetic impulses
increased sympathetic impulses
decreased heart rate
increased heart rate

Explanation:

When baroreceptors detect a fall in blood pressure, the cardioaccelerator reflex is initiated. This reflex activates the sympathetic nervous - system. Sympathetic impulses increase heart rate and cardiac output to raise blood pressure. Parasympathetic impulses would decrease heart rate and cardiac output, which is not the case here.

Answer:

B. increased cardiac output
D. increased sympathetic impulses
F. increased heart rate
