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.
endocytosis
Reabsorption of solutes in the glomerular filtrate primarily occurs through active transport and diffusion in the proximal convoluted tubule of the nephron. Key solutes such as glucose, amino acids, ions, and water are reabsorbed into the bloodstream in this segment of the nephron.
Glomerular filtration rate is the rate at which fluid is filtered by the kidneys. The normal rate for humans is 125mL/min or 180L/day. The fluid that is filtered (and not reabsorbed later) is excreted as urine.
glucose and amino acids, because they are selectively reabsorbed in the proximal convoluted tubule.
Proteins are generally not reabsorbed in the kidney due to their size. The glomerular filtration barrier typically prevents proteins from passing into the filtrate. If proteins are found in the urine, it may indicate a problem with the glomerular filtration process.
Large proteins such as albumin are not reabsorbed in significant quantities in the bloodstream by the nephrons in the kidneys. These proteins remain in the glomerular filtrate and are eventually excreted in the urine.
protein
Glucose is absorbed in the nephron of the kidney, if it is present in very high amounts or unable to be reabsorbed, like with diabetes, it will be present in urine.
Plasma is isotonic to glomerular filtrate, meaning that the concentration of solutes in the two fluids is similar. This isotonicity helps to maintain the balance of fluid and electrolytes in the body.
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.
