Q3. Can a disease in one body system affect homeostasis? If yes, how?



Answer :

Final answer:

Oxygen is absorbed in the lungs, carried to cells for respiration, and exchanged with carbon dioxide.


Explanation:

Oxygen is absorbed by the blood in the lungs and transported through blood vessels to cells where it's needed for cellular respiration, while carbon dioxide is taken from cells and carried back to the respiratory system for removal. This exchange of gases between the respiratory and circulatory systems is crucial for homeostasis.
