Compare the functioning of alvroli in the lungs and nephrons in the kidneys with respect to their structure and functioning
Answers
Answer:
Explanation:
Function of nephron -. The nephron carry out all the important contribution , the kidney make in the maintainance of homeostasis. Nephron are the functional unit of kidney.
These nephron by their cellular activities play their vital role in maintaining constancy of the internal environment through the regulations of blood plasma .
They are takes place under the following heads.
1. Fluid balance regulation.
2. Elimination of nitrogenous waste.
3. Removal of other substance from blood.
4. Maintenance of acid base balance.
Functioning of gases exhange in alveoli
Exhange of gases takes place in the alveoli . Oxygen in the alveoli has a higher partial pressure or concentration than that in the blood .Oxygen in the alveoli into blood through the alveolar .
It passes first into the blood plasma and then combines with the haemoglobin in the red blood corpuscles to farm haemoglobin.
Carbon dioxide in the lungs capillaries has a partial pressure or concentration than that in the alveolie .
Carbon dioxide diffuses from the in two the alveoli. The air of the alveoli.
The alveolar capillaries are narrower than the blood corpuscles so that the latter are squeezed through the capillaries by blood pressure.
The exposes more of their surface are to the gaseous exchange in the alveolie.
