When blood pressure increases
a. baroreceptors detect the change in the carotid arteries.
b. the cardioregulatory center decreases parasympathetic stimulation of the heart.
c. heart rate and stroke volume increase.
d. norepinephrine secretion increases.
When blood pressure increases homeostasis of the body gets disturbed
1. baroreceptors in the carotid arteries and aorta detect an increase in blood pressure
2. the cardioregulatory center increases parasympathetic stimulations and decreases sympathetic stimulation of the heart.
3. the vasomotor center decreases sympathetic stimulation of the blood vessels ( baroreceptor reflex)
4. heart rate and stroke volume decreases, blood vessels dilate, decreasing peripheral resistance
-> homeostasis restored
Correct answer is a. baroreceptors detect the change in the carotid arteries.
