Compare the functioning of alveoli in lungs and nephron in the kidneys with respect to their structure and functioning.

Explanation

Alveoli structure
• Alveoli are tiny balloon like structure present inside the lungs.
• The walls of the alveoli are one cell thick and it conatins an extensive network of blood capillaries.
Function
• The exchange of `O_2` & `CO_2` takes place between the blood of the capillaries that surround the alveoli and the gases present in the alveoli.
• Alveoli are the site of gaseous exchange. Nephrons structure
• Nephrons are tubular structure present inside the kidneys.
• Nephrons are made of glomerulus, bowman.s càpsule, and a long renal tube.
Function
• The blood enters the kidneys through the renal artery. The blood enters here and the nitrogenous waste in the form of urine is collected by collecting duct.
• Nephrons are the basic filtration unit.
