reabsorbed passively in response. This passive movement helps maintain electrical neutrality and osmotic balance in the renal tubule.

mainly glucose (in the renal tubule) and water (in the collecting duct)
The largest volume of water reabsorption in the kidneys occurs in the proximal convoluted tubule. This is the first segment of the renal tubule where approximately 65-70% of the filtered water is reabsorbed back into the bloodstream.
Factors that do not impact how much sodium is reabsorbed include the concentration of potassium in the blood, pH levels, and the presence of certain hormones like oxytocin.
Reabsorption of nutrients in the renal tubule occurs via active transport and facilitated diffusion. Amino acids, glucose and phosphates are reabsorbed at the proximal convoluted tubule via active transport. Water and sodium chloride is reabsorbed at the loop of henle via facilitated diffusion.
Glucose in the filtrate is reabsorbed from the nephron back into the bloodstream through the walls of the renal tubules. This process occurs mainly in the proximal convoluted tubule, where glucose transporters actively reabsorb glucose to maintain its concentration in the blood. If there is excess glucose that cannot be reabsorbed, it may be excreted in the urine.
The two main parts of a nephron are the renal tubule and the renal corpuscle. The renal tubule consists of the proximal convoluted tubule, loop of Henle, and distal convoluted tubule, responsible for filtering and processing the blood. The renal corpuscle contains the glomerulus and Bowman's capsule, where blood is filtered to form urine.
the three main portions of the renal tubule are the proximal convoluted tubule, the loop of henle, and the distal convoluted tubule. the proximal convoluted tubule is the first portion. The proximal (convulated) tubule.
A renal tubule passes most of the fluids it processes into the bloodstream
A nephron consists of a renal corpuscle and a renal tubule. The renal corpuscle includes the glomerulus and Bowman's capsule for filtration, while the renal tubule processes fluid from the glomerular filtrate.
