Answer 2

Inhalation is the process of taking in oxygen and the process of giving out carbon dioxide is called exhalation

our lungs and respiratory system work together and allow us to breathe they help us to take in o2 and send co2 outside the body these processes of taking in o2 is known as inhalation and giving our co2 is known as exhalation

this exchange of oxygen and carbon dioxide is known as respiration
