Question

Vasoconstriction causes
A. Increase in heartbeat
B. Decrease in heartbeat
C. an increase in blood pressure
D. Decrease in blood pressure

Answer 1

Vasoconstriction is that the narrowing (constriction) of blood vessels by little muscles in their walls. Once blood vessels constrict, blood flow is slowed or blocked. Vasoconstriction is also slight or severe. It is going to result from unwellness, drugs, or psychological conditions. It depends upon blood flow.

Complete answer:
It is known as that the narrowing of the blood vessels ensuing from a contraction of the muscular wall of the vessels, particularly the big arteries and little arterioles is called vasoconstriction generally. Once blood vessels constrict, the flow of blood is restricted or shrunken, therefore increasing tube-shaped structure resistance inflicting a discount in blood flow. Thus, constriction sometimes leads to a rise in general pressure.
Eventually, That is known as, high force per unit area, or cardiovascular disease I.e. hypertension, happens once your force per unit area will increase to unhealthy levels. Your force per unit area measure takes under consideration what quantity blood is passing through your blood vessels and also the quantity of resistance the blood meets whereas the heart is pumping. narrow arteries increase resistance.

So, C is the correct option.

Additional information: Abnormal constriction will trigger some health conditions. This includes high vital signs and headache pain. In some cases, an excessive amount of vessel narrowing could also be a facet impact of medicine and foods, like caffeine and salt. It depends upon blood pressure flowing rate.

Note:
Vasoconstriction might occur to:

stabilize vital sign or raise a vital sign
reduce the loss of body heat in cold temperatures commonly
control, however, blood is distributed throughout your body
send a lot of nutrients and gas to organs that require them
