Compare the functioning of alveoli in the lungs and nephrons inthe kidneys with respect to their structureqnd functioning
Answers
1.. Alveoli....
Its the structural n functional unit of lungs
It removes Co2 from blood
They are site of exchange of gases
Alveoli increases the surface area for the diffusion of Co2 and O2
2... Nephron.....
Its the structural n functional unit of kidney
It removes nitrogenous waste
Its the basic filtration unit of kidney
It increases surface area for filtration of blood and reabsorption of useful substances
Hope its helpful... Pls mark me as brainliest
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.
