Which one is not part of nephron ?
- PCT
- DCT
- Loop of Henle
- Collecting duct
The Correct Option is D
Approach Solution - 1
Approach Solution -2
The collecting duct is not the part of nephron.
Nephron is the functional unit of the kidney. It is responsible for the filtration of blood and forming urine. The parts are as follows:
Proximal convoluted tubule (PCT): After the glomerulus, it is the next segment. This segment is responsible for the reabsorption of substances back into the bloodstream.
Loop of Henle: The segment that helps in the concentration of urine is called the loop of Henle. It is a U shaped part and maintains the water balance of the body.
Distal convoluted tubule (DCT): The last segment of the nephron is DCT. After that it gets connected with the collecting duct. It is also involved in reabsorption of substances.
Collecting duct: It is not considered as the part of nephron, but is essential in the process of urine formation. More than one nephron shares the common collecting duct that can gather all the urine and transport it.

Excretory products and their elimination
The physiological process of the elimination of metabolic waste from the body is called excretion. The excretory products comprise amino acids, carbon dioxide, urea, uric acid, water, and ammonia. Some of the Molluscs and Echinoderms excrete waste products from the body in the form of amino acids. Ammonia is the foremost excretory product in animals, it is derived from the proteins exists in the food we eat.
