The Nephron definitions Flashcards

Microscopic functional unit of the kidney responsible for filtering blood and producing urine.

Part of the nephron that filters blood, consisting of the glomerulus and glomerular capsule.

A group of fenestrated capillaries within the renal corpuscle that are highly permeable.

Sheath of tissue surrounding the glomerulus, also known as Bowman's capsule, containing podocytes.

Modified epithelial cells in the glomerular capsule that form filtration slits.

Plasma-derived fluid containing water, electrolytes, and nutrients, collected in the capsular space.

Winding tube in the nephron that modifies filtrate through the proximal tubule, nephron loop, and distal tubule.

First segment of the renal tubule located in the renal cortex, with microvilli to increase surface area.

U-shaped loop in the renal tubule with descending and ascending limbs, involved in filtrate modification.

Final segment of the renal tubule located in the renal cortex, involved in further filtrate modification.

Densely packed cells in the distal tubule that monitor sodium chloride content and help regulate filtration rate.

Tubule that collects filtrate from multiple nephrons and further modifies it, leading to the papillary duct.

Duct formed by the fusion of multiple collecting ducts, where filtrate becomes urine.

Nephrons located primarily in the renal cortex with shorter nephron loops, making up 80% of all nephrons.

Nephrons located at the boundary of the renal cortex and medulla with long nephron loops, specializing in concentrated urine.
