The Respiratory System

Question 5 • Biology - SC3209 IC

Which best describes the respiratory system?

Answer

The respiratory system allows for gas exchange, water and heat balance, and production of sound and speech.

The respiratory system allows for gas exchange, heat balance, and secretion of hormones.

The respiratory system allows for water and heat balance, prevention of disease, and creation of sound and speech.

The respiratory system allows for water balance, muscular support, and passage for ingesting food.

Explanation

The respiratory system brings oxygen into the body and removes carbon dioxide through gas exchange. It also helps regulate water and heat loss in exhaled air, and airflow through the larynx enables sound and speech. These functions match choice A; hormone secretion and muscular support are not primary functions of the respiratory system.
