because your body tries to reduce heat loss to the surroundings so the blood vessels constrict so the blood stays at the core of the body rather than reach the skin where heat will easily be lost to the surroundings.
Hypothermia is known to cause bruising
Yes
High blood pressure is the most common cause of prolonged vasoconstriction in the kidney.
I believe they are stimulants due to the fact that cocaine is a stimulant and it causes vasoconstriction.
The sympathetic nervous system primarily causes vasoconstriction in the body.
sure can
Hypothermia can cause pain as the body's temperature drops, leading to discomfort and potential damage to tissues and organs.
Vasoconstriction is regulated by the autonomic nervous system and various vasoactive substances including norepinephrine, angiotensin II, and endothelin. These substances act on smooth muscle cells in blood vessel walls to cause contraction, leading to vasoconstriction.
No. But the converse is true
No, sympathetic activity typically causes vasoconstriction, not vasodilation.
Primary hypothermia occurs when the body's heat-balancing mechanisms are working properly but are subjected to extreme cold.
Some things that cause low body temp are, exposure to the cold,alcoholism,possibly hypothermia, and some medications can cause this as well.
