When the vasomotor center of our brain wishes to increase blood pressure, it increases ____________ signals causing ______.
dlinn [17]

When the vasomotor center of our brain wishes to increase blood pressure, it increases<u> the heart rate signals </u>causing<u> The greater contraction of the heart causes more blood vessels to constrict, increasing the blood vessels' resistance.</u>

By speeding the heartbeat, making the heart beat harder, and constricting some blood vessels, the sympathetic nervous system increases blood pressure. This will enhance the vessels' resistance.

What controls blood pressure by the vasomotor center?

The vasomotor center modifies the tone of the vascular smooth muscle. Both the local and systemic blood pressure are impacted by this. The vasomotor center produces increased sympathetic tone when blood pressure lowers. This causes an increase in blood pressure.

How is blood pressure regulated?

The autonomic nervous system has short-term control over blood pressure (ANS). Baroreceptors are capable of detecting changes in blood pressure. These are situated in the carotid sinus and aortic arch. High arterial pressure causes the blood vessel wall to stretch, activating the baroreceptors.

What systems regulate peripheral resistance in the vasomotor center?

The vasomotor center in the tunica media regulates smooth muscle contraction or vessel tone. Circulating output is impacted by changes in peripheral resistance, pressure, and flow. The majority of these neurons are in charge of causing sympathetic neurons to release the neurotransmitter norepinephrine.

maksim [4K]

Answer:

C. the effects of an earthquake on blood pressure

Explanation:

Natural experiments are observational studies in which participants are randomly assigned to groups that allow the researcher to draw causal relationships between an event and a factor. These experiments are used in studies where it would be unethical and unacceptable to subject human participants to such conditions. It is most times applied in epidemiological studies.

Since the researcher cannot control an earthquake which is a natural occurrence, this can be rightly described as a natural experiment. Controls are not used in this type of experiment.
