ANATOMY

Detailed explanation-1: -Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream.

Detailed explanation-2: -The majority of water reabsorption that occurs in the nephron is facilitated by the AQPs. Most of the fluid that is filtered at the glomerulus is then reabsorbed in the proximal tubule and the descending limb of the loop of Henle.

Detailed explanation-3: -In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood.

Detailed explanation-4: -Tubular reabsorption occurs in the PCT part of the renal tubule. Almost all nutrients are reabsorbed, and this occurs either by passive or active transport. Reabsorption of water and some key electrolytes are regulated and can be influenced by hormones.

Detailed explanation-5: -Renal tubules: These tiny tubes reabsorb and return water, nutrients and minerals your body needs (including sodium and potassium). The tubules remove waste, including excess acid and fluids through a process called diffusion.
