How do atrial natriuretic peptide and brain natriuretic peptide reduce blood volume'?

ANP and BNP act when myocites are stretched in the heart as a result of fluid volume overload. Although many states could cause this it is most often attributed to ventticular dysfunction in the setting of hear failure. Both ANP and BNP act on tissues throughout the body to promote diuresis (after load reduction) and vascular muscle dilation (preload reduction). ANP and BNP are known to inhibit sensatio of thirst and drinking as well as inhibit the Renin-Aldosterone system causing diuresis (increased urination of fluid) as well as reduction of sodium. Increased endothelial permeability of vasculature allows more diffusion of salts and water out of the blood stream and into the renal vasculature. Hope this helps a little.

What constituents of blood help to maintain adequate fluid volume in the circulatory system?
By secreting Atrial Natriuretic Peptide hormone.
Which hormone is most likely to be released in the body when blood pressure and volume is abnormally high?
atrial natriuretic peptide
What does the hormone Atrial natriuretic peptide do?
It inhibits release of renin from the kidneys and of aldosterone from the adrenal cortex. The result is increased excretion of sodium ions and water from the kidneys and lowered blood volume and blood pressure. Or what you might be looking for is all of the above. :)
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
What does a brain natriuretic peptide do?
When the walls of the atria are stretched by increased blood volume or blood pressure, the cells of the atria produce ANP (atrial natriuretic peptide). ANP's main function is to decrease the reabsorption of sodium ions (by the kidneys) in order to increase the elimination of water (in urine), and decrease blood volume and blood pressure. I'm not sure how much you've studied as far as the endocrine system goes, but it's basically the antagonist to the hormone Aldosterone.
How does Atrial natriuretic peptide reduce blood volume and pressure?
ANP acts to reduce the water, sodium and adipose loads on the circulatory system, thereby reducing blood pressure. ANP has exactly the opposite function of the aldosterone secreted by the zona glomerulosa.
What is the role atrial natriuretic factor?
stimulates urinary sodium excretion when blood volume increases.
What is the hormone secreted by the right atrium?
The hormone secreted by the right atrium is called atrial natriuretic peptide (ANP). It is released in response to an increase in blood volume and helps regulate fluid balance by promoting sodium and water excretion by the kidneys. ANP also plays a role in regulating blood pressure and reducing the workload on the heart.
What is the hormone ANH?
ANH stands for atrial natriuretic hormone. It is released by the atria when to much pressure is bing applied to them (Blood pressure is to high). The hormone inhibits water reabsorbtion in the kidneys, thereby reducing blood volume and lowering blood pressure.
What are the some factors that affect the rate of urine formation?
Factors that effect the normal volume of urine include kidney disease or bladder disease. Drinking enough water can also change the volume of urine.
What is Atrionatriuretic factor?
Atrionatriuretic Factor (ANF) is released from atrial cells in response to increased blood volume. It acts to increase the excretion of sodium by the kidneys in order to reduce extracellular fluid volumes and decrease blood volume.
What are three hormones that regulate the urine volume State where each is made and the specific effect on urine volume?
The 3 hormones that are produced to regulate urine are Aldosterone, AHD (antidiuretic hormone), and ANH (atrial natriuretic hormone). The Aldosterone is released when the blood pressure of the kidney is low. Aldosterones main purpose is to retain sodium and water or the reabsoption of salt. It is secreted by the adrenal cortex (adrenal glands). Antidiuretic hormone is a peptide hormone and is made by the hypothalamus gland it regulates the body's retention of water. A decrease is blood pressure triggers the release of the hormone from the posterior pituitary gland. Atrial Nariuretic hormone is secreted by the heart cells and regulates fluids in the body to help maintain homeostasis. Released ANH causes the kidneys to secret more sodium and lose more water.
