What else can I help you with?
What happen to urine volume if you did not add ADH to the collecting duct?
Without the presence of antidiuretic hormone (ADH), the permeability of the collecting duct to water decreases. As a result, more water is excreted in the urine, leading to a higher urine volume and lower urine concentration.
What happen to urine volume when water intake is decreased?
The urine volume will decrease.
What will happen to urine volume in hypertension patient taking thiazide drug?
Thiazides like hydrochlorotiazyde is a diuretic and it will increase the volume of urine.
What will happen to the volume to urine if large amount of blood loss occur?
Drops significantly.
How do collecting ducts regulate urine volume?
Collecting ducts regulate urine volume primarily through the actions of antidiuretic hormone (ADH), which increases water reabsorption. When ADH is present, it promotes the insertion of aquaporin channels in the duct's cell membranes, allowing more water to be reabsorbed back into the bloodstream, thus concentrating the urine. Conversely, in the absence of ADH, less water is reabsorbed, leading to the production of dilute urine. This mechanism allows the body to maintain fluid balance and homeostasis.
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 structure conveys urine to the renal pelvis?
bowman's capsule. The collecting duct found in Bowman's Capsule passes the urine to the renal pelvis, which is drained by the ureter
What is the liquid stored in the collecting duct of a nephron?
Urine
When the level of ADH increases does less water get reabsorbed by the nephron and collecting duct?
No, when the level of antidiuretic hormone (ADH) increases, more water is reabsorbed by the nephron and collecting duct. ADH enhances the permeability of the collecting ducts to water, allowing more water to be reabsorbed back into the bloodstream. This results in concentrated urine and reduced urine volume. Thus, increased ADH leads to less water being excreted.
Structure most concerned with urine concentration?
collecting duct
How is the calculation of 24 hour urine creatinine done?
To calculate the 24-hour urine creatinine, the amount of creatinine excreted in the urine over a 24-hour period is determined by collecting all urine passed during this time. The creatinine concentration in this pooled urine sample is then measured. Finally, the creatinine concentration is multiplied by the volume of the urine collected to obtain the total amount of creatinine excreted in a 24-hour period.
What happened to volume of urine produced as the volume of water drunk increased?
Volume increases,urine become more dilute and clear.
