The Proximal Convoluted Tubule
The segment of the nephron that is not permeable to water even in the presence of vasopressin is the ascending limb of the loop of Henle. This segment actively reabsorbs sodium and chloride ions, but water remains impermeable, allowing for the concentration of urine.
The thick ascending limb of the nephron loop participates in active transport of salts, specifically sodium, potassium, and chloride ions. This segment plays a crucial role in establishing the high osmolarity in the medulla of the kidney, which is important for concentrating urine.
The tubular fluid has the highest osmolality in the medullary collecting duct as water reabsorption occurs in this segment, concentrating the solutes in the tubular fluid.
The portion of the nephron between the proximal and distal convoluted tubules is the Loop of Henle. This segment plays a crucial role in reabsorbing water and controlling the concentration of urine by creating a concentration gradient in the kidney medulla.
The parts of the proximal tubule in the nephron are the proximal convoluted tubule (PCT) and the proximal straight tubule (PST). The PCT is the first segment after the Bowman's capsule and is responsible for reabsorbing nutrients, ions, and water. The PST continues the reabsorption process and plays a role in maintaining the body's fluid and electrolyte balance.
The distal convoluted tubule is the portion of the nephron that empties into the collecting ducts. It is the last segment of the nephron.
loop of Henle
The loop of Henle is the U-shaped segment of the nephron located in the kidney. It plays a key role in reabsorbing water and salts from the filtrate to maintain fluid balance in the body. The loop of Henle is composed of a descending and an ascending limb.

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.
The correct terms are "Bowman's capsule" and "proximal convoluted tubule (PCT)," followed by "loop of Henle," "distal convoluted tubule (DCT)," "collecting duct," and "peritubular capillary." Bowman's capsule is the initial part of the nephron that surrounds the glomerulus, and the PCT is the first segment of the nephron tubule. Each of these structures plays a crucial role in the filtration and reabsorption processes in the kidney.
Water follows sodium because of the osmotic gradient created by the reabsorption of sodium in the nephrons. Sodium is actively transported out of the nephron, creating a concentration gradient that drives the passive reabsorption of water. Potassium is reabsorbed in a different segment of the nephron and does not create the same osmotic force to drive water reabsorption.
Nothing "does" a segment and, being inanimate, a segment does nothing.
