Where are the kidneys normally located?

A: In the lumbar region.

Q: What are the two main regions of the kidney?

A: The cortex and medulla.

What does the cortex and medulla contain

Cortex: contains most of the nephrons. Medulla: contains the collecting tubules, calyces, and renal pelvis, which help collect and drain urine.

what is the structure of nephrons? GOOD PEOPLE LOVE DRINKING COFEE

Glomerulus + Bowman’s capsule: Filtration takes place here. Small substances are filtered out of the blood to form filtrate. PCT: Most reabsorption takes place here. Useful substances such as glucose, ions and water are returned to the blood. Some substances are also secreted. Loop of Henle (LOH): Helps control water and salt levels. The descending limb reabsorbs water, while the ascending limb reabsorbs ions. DCT: Fine-tunes the filtrate by reabsorbing and secreting ions and other substances. Collecting tubules/ducts: Final adjustments occur here. Water and ions are reabsorbed, and the remaining fluid becomes urine, which drains towards the calyces.

What is the function of nephrons?

FILTERATE FORMATION

What is a nephron

basic structural and functional unit of the kidney

What is glomerulus?

a network of fenestrated capillieries where filteration of blood occurs. it is surrounded by podocytes with filteration slits, which allows small substances to pass through while preventing larger substances like blood cells and most proteins from passing

Bowman’s capsule?

A cup-shaped structure surrounding the glomerulus that collects the filtrate produced during filtration.

(Tubules of the Nephron) Convoluted Tubule?

The PCT is a tightly coiled tubule containing microvilli and many mitochondria. It actively reabsorbs useful substances from the filtrate into the blood and secretes unwanted substances into the filtrate.

Nephron Loop?

Descending limb : freely permeable to water - reabsorbs. Ascending limb: less permeable secretes.

Distal Convoluted Tubule:

No microvilli – secretes.

Collecting Tubules:

Specialised cells function to aid pH regulation by excreting H+ ions. Na+ and H2O regulation (water is reabsorbed under influence of ADH through aquaporins).
