Question

Difference between alveoli and nephron?

Answer 1

1. Alveoli are the small air sacs that are present at the end of the bronchioles where the lung and the blood exchange oxygen and carbon dioxide for the process of breathing.
2. Nephrons are the tiny or minute structural and functional units of the kidney.

S.no	Alveoli	Nephron
1.	They are the site for an exchange of gases.	They are the site for filtration.
2.	They are found in the lungs and are very tiny balloon-like sacs.	They are found in the kidneys and are very small tubular structures.
3.	It has thick walls which comprise a network of richly supplied capillaries.	It has clusters of thin-walled capillaries and is made up of glomerulus, renal tube, and Bowman’s capsule.
4.	Its function is to carry out the exchange of carbon dioxide and oxygen which occurs between the blood capillaries that surround alveoli and the gases present inside the alveoli.	The blood follows the path. The renal artery – kidney branches- capillaries. At the Bowman’s capsule, the water and the solutes get shifted towards the nephron which then moves to the proximal tube, down to Henle's loop.
