Question

how lungs are similar to Kidneys with respect to their functions

Answer 1

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

Alveoli Nephrons

Structure Structure

Alveoli are tiny balloon-like structures present inside the lungs. Nephrons are tubular structures present inside the kidneys.

The walls of the alveoli are one cell thick and it contains an extensive network of blood capillaries. Nephrons are made of glomerulus, bowman’s capsule, and a long renal tube.

Function Function

The exchange of O2 and CO2 takes place between the blood of the capillaries that surround the alveoli and the gases present in the alveoli. 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.

Alveoli are the site of gaseous exchange. Nephrons are the basic filtration unit.

Answer 2

The only similarity between the functionality of kidney ad lungs is that, both of the organs play a role in filtration; lungs clean up the air whereas kidney filtrate nitrogenous wastes from blood.

In lungs, alveolar sacs are present which are surrounded by blood capillaries which clean up the blood whereas in kidney, nephron is the smallest unit which filtrates the blood and produce urine.
