Concentrated urine forms because ADH is present which absorbs water. As tubular fluid flows down the descending convulated tubule, the water osmotic decreases. As it flows through the ascending tubule the water osmotic increases, becasue water is impermeable in ther ascedning Loop of Henle, so while Na and K are being taken out, water is not. There is also a counter current flow that happens in the LOH.
Yes a men's urine comes from a penis, a woman's from a vagina!(: x
Bleach alone is toxic. So mixing it with urine, might dilute it if anything
There should be no difference in the color or amount of urine for teens or adults. Urine should be a clear yellow to light amber color. If it is darker, the person has probably not had enough fluids.
Maybe a little, but the guys in the lab know the difference between tap water and urine. If you add tap water to your urine sample, they're just going to call you back for a retest and make someone watch you the entire time. There's also the possibility of you getting on trouble for intentionally diluting it. this really depends on where you live as well as the reason for the drug test.
Unspun urine is a quantitative oil immersion method to identify white cells and bacteria in UTI .
aldosterone is the hormone that decides this
The color of urine is determined on how concentrated the urine is. It's from all of the toxins being excreted. In the morning it's a fasting urine and you haven't drank fluids all night. So it's concentrated and dark yellow. During the day, you drink and dilute the urine so there more water in the urine, less concentrated and lighter in color
ADH causes an increase in water reabsorption in the kidneys. Thus, by absorbing more water, the urine becomes MORE concentrated (more compounds in less water = more concentrated)
Concentrated, the more excess water is present in the body the more dilute the urine becomes.
since your bodies goal is homeostasis the more fluids in, the more out. Certainly metabolic rates and diet can have an effect, but generally speaking your body produces more dilute urine during daytime.
Urine is yellow due to the presence of a pigment called urobilin. When urine is dilute,its colour becomes light due to the abundance of water. Dark yellow urine shows that the urine is concentrated which is because of dehydration.
Will a woman's what dilute a mans urine?A woman's urine?Not really, they are essentially the same aside from a slight variance in hormones.
-Increase water intake, or water loading, will result in dilute urine in person not diagnosed with any kidney condition. This will happen because of an incease in water being absorbed in the bloodstream which will then become part of the plasma.This event will lead to an increase in blood volume. The increase blood volume will further lead to an increase in glomerular filtration rate in kidney which will lead result in excess formation of urine which is dilute in nature.
Glucose is high in the urine of an untreated diabetic. Glucose itself makes the urine hyperosmolar (concentrated with solutes), which in turn makes it absorb extra water from surrounding tissues, which creates extra, dilute urine. This in turn dehydrates the surrounding tissues making the patient thirsty.
As adh aids in the reabsorbtion of water in the kidneys urine becomes more concentrated so urine becomes darker.
