A decrease in the diameter of a blood vessel is termed?
vasoconstriction.
What hormone reduces blood pressure and blood volume by inhibiting nearly all events that promote vasoconstriction and soduim ion and water retention?
atrial natriuretic peptide
Would vasoconstriction of the renal arteries decrease blood flow to the kidneys?
Yes. If you constrict the afferent arteriole then renal blood flow will decrease.
Differences between vasodilation and vasoconstriction?
Vasodilation is relaxation of blood vessels leading to increase in lumen size. Vasoconstriction is contraction of blood vessels leading to decrease in lumen size.
What hormone regulates blood composition and blood volume when it acts on the kidney?
Thyroid hormone
What hormone works with the parathyroid hormone to decrease calcium levels in the blood and tissues?
calcitonin
What is vasoconstriction?
Vasoconstriction is the constriction or narrowing of blood vessels by small muscles in their walls, slowing or blocking blood flow. Vasoconstriction is the constriction of blood vessels that increases blood pressure.
What is the hormone that decreases blood volume?
anp
Increases in the hormone insulin lead to?
decrease of blood glucose levels
How does vasoconstriction and vasodilation of blood vessels effect blood pressure?
No. Vasoconstriction is a squeezing of the veins. This is like putting your thumb at the end of a garden hose. The constriction of the flow increases the pressure. The water shoots out faster from the hose when your thumb is blocking the way. If the entire hose were to tighten, as in vasoconstriction, the same effect happens.--From Wikipedia: Vasoconstriction"Generalized vasoconstriction usually results in an increase in systemic blood pressure..."
Substance made in the kidney that increases blood pressure?
Renin - hormone secreted by the kidney; it raises blood pressure by influencing vasoconstriction (narrowing of blood vessels) From: DAVI-ELLEN CHABNER THE LANGUAGE OF MEDICINE
How would you explain what vasoconstriction mean?
