Question

_______, meaning to "breathe again," is the exchange of gases between the body and its environment.
A) Bronchus
B) Respiration
C) Expiration
D) Exhalation

Accepted Answer

Respiration is the process by which gases, such as oxygen and carbon dioxide, are exchanged between an organism and its environment. This includes both inhalation and exhalation, but also involves the transport and utilization of gases in the body's cells. The word "respiration" comes from the Latin word "respirare", which means "to breathe again". Choices A, C, and D all refer to specific aspects of the respiration process, but do not encompass the entirety of gas exchange.
