Answer :

Final answer:

The respiratory system plays a crucial role in gas exchange, providing oxygen to tissues and removing carbon dioxide, thus supporting cellular functions.


Explanation:

Gas exchange is a vital function of the circulatory system, involving the transport of oxygen and carbon dioxide between specialized respiratory organs and body tissues. The respiratory system primarily functions to supply oxygen for cellular respiration, remove carbon dioxide, and maintain acid-base balance. Apart from these essential roles, it also aids in non-vital functions such as sensing odors and speech production.
