Answer 1

Answer:

Respiration is Gas Exchange. While pulmonary ventilation is the process by which oxygen enters and carbon dioxide exits the alveoli, respiration is the process by which oxygen and carbon dioxide diffuse in and out of the blood.

Answer 2

The process which involves exchange of gases is called respiration.

Explanation:

• Respiration is a chemical reaction that happens in all living cells, including plant cells and animal cells.

• It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen.

• The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies and send carbon dioxide out.

• This exchange of oxygen and carbon dioxide is called respiration.

• The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.
