Are drugs that cause vasoconstriction stimulant or depressants?
I believe they are stimulants due to the fact that cocaine is a stimulant and it causes vasoconstriction.
What type of muscle tissue causes vasoconstriction?
Smooth muscle tissue causes vasoconstriction. This type of muscle tissue is found in the walls of blood vessels and is responsible for regulating blood flow by constricting and dilating the vessels.
What raises smokers blood pressure?
Nicotine contained in tobacco causes vasoconstriction and increases BP.
Does the sympathetic nervous system cause vasoconstriction?
Yes, the sympathetic nervous system causes vasoconstriction by activating alpha-adrenergic receptors on blood vessels. This response helps regulate blood pressure and redirect blood flow to vital organs during fight-or-flight situations.
In which organ hypoxia cause vasoconstriction and what is the mechanism?
Hypoxia in the lungs causes vasoconstriction due to the release of hypoxic vasoconstrictor substances like endothelin-1 and serotonin in response to low oxygen levels. This vasoconstriction helps redirect blood flow to well-ventilated areas of the lungs, optimizing gas exchange.
Contraction of a vessel is called?
Vasoconstriction
Does Renin cause a decrease in blood pressure?
No. Renin causes the blood pressure to rise. By low blood pressure the body releases Renin from the kidneys. Renin cleaves an inactive peptide, called Angiotensinogen, converting it to Angiotensin I. Angiotensin I is then converted to Angiotensin II by ACE (Angiotensin-Converting-Enzyme). Angiotensin II causes vasoconstriction and thus an increase in blood pressure.
What kind of molecule is an enzyme-?
The type of molecule that is an enzyme is a protein molecule.
What enzyme is a kind of .?
catalyst.
Does sympathetic stimulation cause vasodilation of which arterioles?
Sympathetic stimulation causes vasoconstriction of most arterioles in the body, except for arterioles in skeletal muscle and the heart where it causes vasodilation.
The enzyme cholinesterase causes acetylcholine to what?
Decompose
What enzyme deficiency causes disease?
Tay-Sachs disease (TSD) is a fatal condition caused by a deficiency of the enzyme hexosaminidase A (Hex-A).
