Is it possible to excrete urine more concentrated than plasma in the absence of ADH?
Yes, it is possible to excrete urine more concentrated than plasma even in the absence of antidiuretic hormone (ADH). This can occur through mechanisms such as the countercurrent multiplication system in the kidneys, which allows for the generation of a hyperosmotic medullary interstitium. Additionally, certain renal transport processes can concentrate solutes in the urine, although the absence of ADH would limit the overall capacity for water reabsorption, affecting urine concentration.
How do you dissolve salts in your urine bottle?
It is not recommended to dissolve these salts; they are elements for the clinical analysis.
What is composed of water urea and excess mineral salts?
Urine is composed of water, urea, and excess mineral salts. Urea is a waste product produced by the liver when it breaks down proteins, and excess mineral salts like sodium, potassium, and chloride are filtered out of the blood by the kidneys and excreted in urine.
Neurohypophyseal secretion of stimulates formation of concentrated urine?
The neurohypophyseal secretion of ADH (antidiuretic hormone) promotes water reabsorption in the kidneys, leading to the formation of concentrated urine. ADH acts on the collecting ducts of the nephrons in the kidneys to increase their permeability to water, allowing the body to conserve water and produce concentrated urine.
Where is urea primarily concentrated from?
Urea is primarily concentrated in urine, as it is a waste product produced by the liver during the breakdown of proteins. It is filtered out of the blood by the kidneys and excreted in the urine.
Why are bumble bees swarming dog's urine?
They are attracted to the urine. The salts in the urine are utilized by bees so this is why they drink it at times.
Compare the composition of blood plasma and urine?
Blood plasma contains water, electrolytes, proteins, hormones, gases, and waste products. Urine is a byproduct of blood filtration in the kidneys and consists of water, urea, salts, creatinine, and other waste products. The composition of urine is more concentrated compared to blood plasma.
Is it possible to excrete urine more concentrated than plasma in the absence of ADH?
Yes, it is possible to excrete urine more concentrated than plasma even in the absence of antidiuretic hormone (ADH). This can occur through mechanisms such as the countercurrent multiplication system in the kidneys, which allows for the generation of a hyperosmotic medullary interstitium. Additionally, certain renal transport processes can concentrate solutes in the urine, although the absence of ADH would limit the overall capacity for water reabsorption, affecting urine concentration.
What does it mean when you have concentrated urine?
Concentrated urine indicates that the kidneys are filtering out excess water while retaining necessary substances, resulting in a higher concentration of solutes like salts and waste products. This often occurs when the body is dehydrated or when fluid intake is low, signaling that the body is conserving water. Concentrated urine can also be a sign of certain medical conditions, such as diabetes insipidus or kidney dysfunction, depending on other symptoms present.
Why is the first urine of the day most concentrated?
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
What is the urine-producing unit in the kidney called?
Nephrons. This includes the glomerulus where the blood stream encounters a connective tissue filter, the loop of Henle where the filtrate is concentrated and salts are exchanged and the collecting duct into which urine is collected.
What can be done about someone with high concentrated urine?
Someone with highly concentrated urine may be dehydrated, and fluids may help.
How can one make urine more concentrated?
To make urine more concentrated, drink less water and consume foods high in salt and protein. This will reduce the amount of water in the body, leading to more concentrated urine.
Why osmotic balance is matained in blood?
The kidney performs this function and it is thus:when the blood is more concentrated as in sugar,salts and so on we say the blood is hypertonic to the cells and this could shrink the cell but the kidney filter this salts from the blood and reabsorbs more water and a more concentrated urine is produced by anti dieretic hormone,but also sometimes the blood is hypotonic in terms of salts and so on in this case the kidney reabsorbs less water and restores some vital salts..so osmotic pressure is regulated.
What is a product of the kidney?
Concentrated Urine.
Is urine always hyper tonic to the blood plasma?
It depends. If the body is dehydrated, it will produce highly concentrated (hypertonic) urine in order to conserve water from the blood stream. If your blood is hypotonic (contains excess water), then the kidneys will release hypotonic urine, to reduce the amount of water in the blood. Therefore, if you are dehydrated, the urine is considered hypertonic to the blood. If not, the urine is hypotonic to the blood.
Diseases in which bile salts appear in urine?
If you think too much bile salts appear in the urine, if you're an a s s h o l e, then probably no bile salts will be there
