Kidney The kidney has a complex structure with various regions, each serving different functions.Key histological features include:

-Cortex: The outer part of the kidney where you'll find the majority of glomeruli (renal corpuscles), proximal and distal convoluted tubules, and some parts of the collecting ducts.- Medulla: The inner part of the kidney consisting of renal pyramids, primarily containing loops of Henle, collecting ducts, and vasa recta.The medulla's collecting ducts eventually drain into the renal pelvis.

The kidney has a complex structure with various regions, each serving different functions. Key histological features include:

-Cortex: The outer part of the kidney where you'll find the majority of glomeruli (renal corpuscles), proximal and distal convoluted tubules, and some parts of the collecting ducts. It's richly supplied with blood vessels.

• Medulla: The inner part of the kidney consisting of renal pyramids, primarily containing loops of Henle, collecting ducts, and vasa recta. The medulla's collecting ducts eventually drain into the renal pelvis.

-Glomerulus: A network of capillaries surrounded by Bowman's capsule. This is where filtration begins, leading to the formation of urine.

-Proximal Convoluted Tubule (PCT): This section is responsible for reabsorbing most of the filtrate. The cells here have microvilli, creating a "brush border" that increases the surface area for reabsorption.

-Distal Convoluted Tubule (DCT): After the loop of Henle, this segment further processes the filtrate, adjusting electrolyte levels. It lacks the brush border of the PCT.

• Collecting Ducts: These ducts gather filtrate from multiple nephrons and lead it through the medulla to the renal pelvis. They play a role in water reabsorption, influenced by hormones like ADAS.
