Water is present in both urine and glomerular filtrate. Glomerular filtrate is the fluid that is filtered from the blood through the glomeruli in the kidneys, containing water, electrolytes, and small molecules. As this filtrate passes through the renal tubules, water is reabsorbed back into the bloodstream, and the remaining fluid, which becomes urine, contains a lower concentration of water and waste products. Ultimately, urine has a different composition than the original glomerular filtrate due to this selective reabsorption process.
What else can I help you with?
Is water concentration in urine the same as glomerular filtrate or greater?
The water concentration in urine is generally lower than that in glomerular filtrate. During the filtration process in the kidneys, glomerular filtrate contains a high concentration of water, but as it passes through the renal tubules, water is reabsorbed, leading to a more concentrated urine. Therefore, urine typically has a higher concentration of solutes and a lower concentration of water compared to the initial glomerular filtrate.
What substances are in both urine and glomerular filtrate?
Both urine and glomerular filtrate contain water, urea, electrolytes (such as sodium and potassium), and creatinine. Glomerular filtrate is the fluid that passes from the blood into the renal tubules, while urine is the final product after further processing and concentration by the kidneys. As glomerular filtrate is modified during its passage through the nephron, some substances are reabsorbed or secreted, leading to differences in composition between the two.
When less glomerular filtrate is formed what kind of urine is formed?
less urine is formed
Difference between filtrate and urine?
Until the liquid reaches the renal pelvis, it is "glomerular filtrate," when it reaches the pelvis, it is called "urine"
What is used to form urine and requires a high blood pressure?
Glomerular filtrate
What percent of the glomerular filtrate is reabsorbed?
the nephrons produce approx 150 litres of glomerular filtrate per day 99% of which is reabsorbed to leave an average of 1.5litres of urine.
Glucose is found in glomerular filtrate but NOT in the urine because?
glucose is transported back into the bloodstream
What happens to the glomerular filtrate as it passes to the ureter?
As the glomerular filtrate passes through the renal tubules, it undergoes reabsorption of water, ions, and nutrients back into the bloodstream. Waste products and excess substances that were not reabsorbed are left behind and eventually become urine. The final urine then passes through the ureter into the bladder for storage and eventual elimination.
What Compounds are found in urine which is not present in glomerular filtrate?
Compounds found in urine that are typically not present in glomerular filtrate include urea, creatinine, uric acid, and various metabolites. These substances result from metabolic processes and are actively secreted or concentrated by the renal tubules after the initial filtration of blood. Additionally, certain hormones and excess electrolytes may also be present in urine but not in the filtrate.
Why is there protein in the glomerular filtrate and urine?
The inflammation would increase the permeability of your glomeruli. This retraction of the epithelium will allow the larger protein molecules to go through the filtrate.
Why is there no protein in the glomerular filtrate or unine?
Protein is typically absent in glomerular filtrate and urine due to the selective permeability of the glomerular filtration barrier, which consists of endothelial cells, a basement membrane, and podocytes. These structures prevent large molecules like proteins from passing through while allowing smaller molecules and water to filter through. Additionally, any small amounts of protein that may enter the filtrate are usually reabsorbed by renal tubules before urine formation. Therefore, healthy kidneys maintain minimal to no protein levels in urine.
How does ADH act upon the glomeruli?
ADH (anti-diuretic hormone) acts on the glomeruli by increasing their permeability to water. This allows for water reabsorption from the glomerular filtrate back into the bloodstream, reducing urine volume and concentrating the urine.
