Muscles in the blood vessels are the effectors that cause Vasodilation and Vasiconstriction.
Paracrines act locally but, affect all cell types other than those releasing Paracrines chemicals. Hormones are long distance chemical signals that travel in blood or lymph throughout the body.
Vasodilation causes a drop in blood pressure.
Paracrines are a group of local hormones that work on nearby cells. Autocrines stimulate the same cell and circulating hormones can travel long distances to stimulate cells. Hormones only stimulate cells that have their specific receptor.
I am not 100% sure if dehydration could cause vasodilation (swelling of a blood vessel), although it does make sense. As the temperature of the body rises, the blood vessels expand to release heat quicker. If one becomes dehydrated, and is then covered in ice packs, they may experience vasoconstriction, causing the blood vessels to constrict and hold heat in more, which would be unwanted.So if you were asking if dehydration causes dilation of the blood vessels, then yes.

CAuse it does.
Low oxygen levels cause vasodilation in systemic arterioles.High oxygen levels cause vasodilation in capillaries in the lungs.
no
Stress is far more likely to cause vasorestriction
chemicals released by the injured tissue cells and leukocytes cause the VASODILATION of the arterioles in the injured area and cause the local hyperemia to form accounting for the redness and heat.
Yes, they are.
No it causes them to dilate (vasodilation)
friction
Paracrines
A gaseous hormone that can bind to hemoglobin and be released to cause local vasodilation is nitric oxide. Nitric oxide is also known as nitrogen oxide.
