WebThe nephron is the structural and functional unit of the kidney. All of the excretory processes happen in the nephron with one or more occurring in each of its parts– from … WebOnly about 1.5 to 2% of the fluid is excreted as urine. For this reabsorption to occur, different parts of the nephron actively secrete and reabsorb different electrolytes, which pull the water along, and other parts of the nephron vary their permeability to water, allowing more or less water to return to the circulation.

WebOct 25, 2024 · The nephron loop is the U-shaped bend of a nephron which extends through the medulla of the kidney. Histologically, it consists of two parts; thin descending and thin ascending limbs. Both limbs are composed of simple squamous epithelium. The cells have few organelles, little to no microvilli and low secretion abilities. A nephron is the basic unit of structure in the kidney. A nephron is used separate to water, ions and small molecules from the blood, filter out wastes and toxins, and return needed molecules to the blood. The nephron functions through ultrafiltration.
