1 National Council on Radiation Protection (NCRP). 2  Examines the literature on biological effects of exposure to modulated radiofrequency (RF) energy to determine whether present exposure standards and guidelines need to be modified further to take modulation into account.
Vasoconstriction. by admin Leave a Comment. Vasoconstriction is the process of constriction of blood vessels, which may result in decrease of flow of blood. Normal blood flow is necessary for carrying oxygenated blood to all parts of the body and when the normal flow is disrupted it may cause various problems.our doctor should find out the underlying factors that cause vasoconstriction before giving treatment. He may prescribe alpha adrenoreceptor antagonist (which is a vasodilator) for reducing the constriction of blood vessels and increasing blood flow.
IB Biology Notes for Homeostasis & Excreton When body temperature is too low, it is known as hypothermia. vasoconstricton decreases the diameter of blood vessels in the skin, in order to keep heat in the body core (where vital organs are) shivering produces heat by rapid contractons of skeletal muscles
