Explain the structure of a nephron.
Answers
Answer:
A nephron is the structural and functional unit of the human kidney.
It is composed of two parts:-
1. Malphigian Corpuscles:
It further consists of two parts-
a) Glomerulus- The afferent arteriole that comes to the nephron containing waste products gets divided into many small fine capillaries. These capillaries form a bunch inside the lumen cavity of Bowman's capsule. This capillary bunch is called Glomerulus.
b) Bowman's Capsule- It is a double-layered cup like structure. This structure is called Bowman's Capsule.
2. Renal tubules:
It consists of three parts:-
a) Proximal Convoluted Tubule (PCT):- It is the portion after Bowman's Capsule and opens into Loop of Henle. Its main function is selective reabsorption of substances.
b) Distal Convoluted Tubule (DCT):- It is the posterior part of nephronic tubule. Its main function is tubular secretion.
c) Henle's Loop:- It contains ascending and descending limb.
