Answer 2

Answer:

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

Alveoli and nephron act as the structural and functional units of lungs and kidneys respectively. Alveoli occur in the respiratory system while the nephrons occur in the excretory system. The cell wall of alveoli and nephrons is thick and surrounded by blood capillaries. Let us have a detailed look at the differences between alveoli and nephrons with respect to their structure and function.
