Question

compare the functioning of alveoli in the lungs and nephrons in the kidney with respect to thier structure and function

Answer 1

Structure
Alveoli - Their shape is like balloon . They are surrounded by blood capillaries.
Nephron - They are long shaped structures that are made up of renal tubule and renal corpuscles.
Function
Alveoli- They help in the exchange of gases
Nephron - They help in the filtration of blood and formation of urine

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.
