Question

tell me about internal structure of kidney

Answer 1

Kidney is Like a upside down pear like shape.
In Kidney they have Nephrons in it which has Tiny filters which are small tubes that has neurons which filters the blood from all waste material like salt, ammonium and other waste material

Answer 2

INTERNAL STRUCTURE OF KIDNEY—

Nephron:

Each kidney consists of more than one million nephrons or uriniferous tubules. The total length of all tubules combined will be more than 600 km. Nephron is the functional unit of a kidney. Each nephron consists of a malpighian capsule or renal tubule, a nephric tubule (secretory part of uriniferous tubule) and a collecting tubule.

Malpighian capsule or Malpighian body it has two parts a Bowman’s capsule and a glomerulus.

Bowman’s Capsule:

It forms the dilated blind end of the nephron. It is a double-walled cup-shaped
structure. It is lined by a thin semipermeable squamous epithelium. The outer concavity of Bowman’s cup contains a knot-like mass of blood capillaries called glomerulus.

Glomerulus:

The afferent arteriole enters in Bowman’s capsule and divides into a bunch of about 50 capillaries. This bunch is called glomerulus. Their diameter gets reduced to increase the blood pressure. These capillaries reunite to form efferent arteriole.

Nephric or Uriniferous Tubule:

It is a long, coiled tubule and can be divided into three major regions the proximal convoluted tubule (PCT), the loop of Henle and the distal convoluted tubule (DCT).

Collecting Ducts and the Ducts of Bellini:

Collecting ducts are larger ducts, each receiving collecting tubules from several nephrons. These pass into the renal medulla and join with each other forming still larger ducts of Bellini. These drain the urine collected from the nephrons into the pelvis which leads to the ureter.
