Question

compare the functioning of alveoli in the lungs and nephrons in the kidney with respect to their stricture and functioning

Answer 1

Alveoli:
Alveoli are tiny balloon-like structures present inside the lungs.
The walls of the alveoli are one cell thick and it contains an extensive network of blood capillaries.
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.
Alveoli are the site of gaseous exchange.

Nephron:
Nephrons are tubular structures present inside the kidneys.
Nephrons are made of glomerulus, bowman’s capsule, and a long renal tube.
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
Nephrons are the basic filtration unit.

Answer 2

ALVEOLI IN LUNGS :-

1. Alveoli are balloon like structures.

2. It is made up of one celled thick wall which contains extensive network of blood capillaries.

3. Alveoli are the site of gaseous exchange in lungs. Exchange of oxygen and carbon dioxide takes place between the blood flowing in capillaries which surround the alveoli and gases present in the alveoli.

NEPHRONS IN KIDNEY:-

1. Nephron are long tubular structures.

2. It is made up of glomerulus , Bowman's capsule and a long renal tube.

3. Nephron are the basic filteration unit of kidney. Each nephron filters the blood and separates the nitorgenous waste in the form of urine.
