Compare the Functioning of Alveoli in the Lungs and Nephrons in the Kidneys with respect to their Structure and Functioning.

12 Important Comparing factors between Alevoli And Nephrons with respect to their Location Structure and Functioning are as Follows-

	Difference	Alveoli	Nephrons
1	Location	Alveoli are in the Lungs	Nephrons are in the Kidneys
2	Structure	Alveoli are balloon-like structures found with in the lungs.	Nephrons are long, coiled tubule-like structures present within the kidneys.
3	Structure (Type of cell)	Alveoli are made up of simple squamous epithelium	Nephrons are made up of simple cuboidal epithelium with a few microvilli
4	Blood Supply	The thin-walled alveoli contain an extensive network of blood vessels.	Nephrons contain a bundle of blood capillaries called Glomerulus.
5	Blood Supply	Blood is supplied to Alveoli by Pulmonary Arterioles.	Blood is supplied by Afferent Arterioles to Nephrons.
6	Blood Supply	Alveoli are surrounded by blood capillaries that link pulmonary arterioles to pulmonary veins	Nephrons are surrounded by two types of capillaries: glomerulus and peritubular capillaries
7	Blood Supply	Alveoli Supplies blood to pulmonary venules.	Nephrons supplies blood to renal vein.
8	Structure	Alveoli provide a large surface area, where exchange of gasses can take place.	The tubular part of nephron also contains blood vessels for reabsorption of useful substances.
9	Functioning	Alveoli is the site of gaseous exchange.	Nephrons are the basic filtration unit Which filters blood to produce urine The blood enters the kidneys through the renal artery. The blood is entered here and the nitrogenous waste in the form of urine is collected by collecting duct.
10	Functioning	The exchange of O2 and CO2 takes place between the blood of the capillaries that surround the alveoli and the gasses present in the alveoli.	Nephrons help in filtering waste from blood, so that only harmful products are eliminated.
11	Functioning	The phenomenon of diffusion is employed in exchange of gasses in alveoli.	Nephrons apply selective reabsorption of useful substances into the blood capillaries.
12	Functioning	A large number of alveoli are present in lungs.	Nephrons are very small in size, but are large in number in each kidney.
