Comparison b/w alveoli and nephron:
1-Alveoli
⇒Alveoli have thin walled balloon-like structure.Surface is fine and delicate.
⇒Alveoli are supplied with extensive network of thin walled blood vessels, i.e capillaries for exchange of gases.
⇒They increase surface area for diffusion.
⇒They only provide surface for exchange of gases only in lungs.
2-Nephron
⇒Nephrons have thin walled,cup-shaped structure attached with thin walled tubule.
⇒They also increase surface area for filtration of blood.
⇒Tubular part of nephron also carries the urine to collecting duct.
⇒A large number of nephrons, the basic filtration unit are present in each kidney
