an increase in blood pressure detected by baroreceptors will result in the cardioinhibitor reflex, leading to what effects?
□ decreased cardiac output
□ increased cardiac output
□ increased parasympathetic impulses
□ increased sympathetic impulses
□ decreased heart rate
□ increased heart rate

Explanation:

When baroreceptors detect an increase in blood pressure, the cardioinhibitor reflex is activated. This leads to increased parasympathetic (vagal) impulses which slow down the heart rate (decreased heart rate), and also result in decreased cardiac output as the heart contracts less forcefully and at a slower rate. Sympathetic impulses are decreased during this reflex response to counter - act the high blood pressure.

Answer:

Decreased cardiac output
Increased parasympathetic impulses
Decreased heart rate
