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.

ADH (antidiuretic hormone) and aldosterone act on the kidneys to increase water reabsorption, decreasing the amount of water excreted in urine. ADH makes the kidneys more permeable to water, reabsorbing more water back into the bloodstream. Aldosterone, on the other hand, promotes the retention of sodium and water to help regulate blood pressure and electrolyte balance.

What are the some factors that affect the rate of urine formation?

Factors that affect the rate of urine formation include hydration levels, blood pressure, hormones (such as ADH and aldosterone), and kidney function. Dehydration can lead to concentrated urine production, while adequate hydration helps maintain a normal urine output. Hormones regulate the reabsorption of water and electrolytes in the kidneys, impacting urine volume.


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?

The tumor would cause increased secretion of glucocorticoids and decreased aldosterone production, leading to increased sodium and water retention in the kidneys. This would result in increased urine volume and decreased urine concentration, leading to dilute urine with low sodium levels.


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.


What would happen to total glomerular filtration and urine production in a human kidney if all the collecting ducts were blocked?

Total glomerular filtration would decrease due to the blockage of the collecting ducts, leading to reduced urine production. This blockage would prevent the reabsorption of water and solutes from the tubular fluid, resulting in a higher concentration of solutes in the urine that is formed.

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.


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.


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.


Does Both ADH and aldosterone tend to reduce the amount of urine produced?

yes

Which of the choices below exerts primary control over sodium levels in the body?

The kidney exerts primary control over sodium levels in the body by regulating the reabsorption and excretion of sodium ions in the urine. Hormones such as aldosterone also play a key role in controlling sodium levels by influencing the reabsorption of sodium in the kidney.


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.
