Why do the hormones ADH and aldosterone decrease urine production?

It's a rather confusing concept when learning Anatomy especially since we know that BOTH increase your BV and H20 Levels so why does our urine output decrease? You must remember that these increase water re-absorption in your system, if your body is secreting less filtrate and re-absorbing more... You're going to have a decreased urine output.

What hormone that decides dilute or concentrated urine will be formed?
aldosterone is the hormone that decides this
Which hormone limits sodium excretion in the urine to help maintain your electrolyte balances during excessive sweating?
Aldosterone is the hormone that limits sodium excretion in the urine. It is released by the adrenal glands in response to low blood pressure or low blood sodium levels. Aldosterone acts on the kidneys to increase the reabsorption of sodium and water, helping to maintain electrolyte balance during excessive sweating.
If a tumor of the glucocorticoid-secreting cells of the adrenal cortex crowds out the cells that produce aldosterone what is the likely effect on urine composition and volume?
increase urine composition and increace volume
Is dark urine color during pregnancy ok?
yes its your hormones
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 two hormones work together to decrease the amount of urine?
Epinephrine and Norepinephrine. They're part of the "fight or flight" responses in one's body ultimately slowing down the body's urine production.
What is the role of aldosterone?
Aldosterone promotes water retention and reduces urine volume
What are the functions of the distal convoluted tubule in urine production?
absorption of more Na+ (if aldosterone present) and absorption of more water (if ADH is present)
How does aldosterone modify the chemical composition of urine?
The higher the aldosterone levels, the more sodium that is reclaimed and the more potassium that is lost.
What hormone causes the kidneys to reabsorb sodium and water?
Vasopressin and ANP reduce water loss in urine. I don't remember which hormone reduces sodium loss in urine.
Which hormones is most likely to cause production of a concentrated urine?
Antidiuretic hormone(ADH) reabsorbs water from the collecting tubules of the kidney causing urine to become concentrated.
Does Both ADH and aldosterone tend to reduce the amount of urine produced?
yes
What hormone that decides dilute or concentrated urine will be formed?
aldosterone is the hormone that decides this
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.
14.How does aldosterone decrease urine volume What does ANH do?
ANH opposes the action of aldosterone by inhibiting the recovery of Na+ by the DCT and collecting ducts. More Na+ is lost, and as water follows, total blood volume and pressure decline. In low-pressure states, ANH does not seem to have much effect. ADH is also called vasopressin
How does a drop in the blood pressure affect urine output?
As blood leaves the vascular system pressure drops, leading to a decrease in perfusion to the kidneys. This causes a decrease in urine production. Put simply fluid is going in to some space in your body instead of leaving through the urine.
When there is more aldosterone being secreted a patients urine will appear light in color?
true
