True or false

Answer 1

Answer:

true

Explanation:

we breathe out all the CO2 that is present in our lungs during exhalation

during inhalation, it's mostly 02

Answer 2

True, the percentage of carbon dioxide present in exhaled air is higher than the air inhaled.

Explanation:

Respiration is a process through which air is inhaled through nostrils, exchange of gases happens in the lungs and it is exhaled through nostrils.

Process of exchange during respiration happens as below:

• Oxygen present in air inhaled and exchanged with carbon dioxide present in the blood. So the air exhaled has higher amount of carbon dioxide. After the exchange of gases the lungs are enriched with oxygen, which infuses in the blood.
• Blood while circulating throughout the body collects carbon dioxide present and provides with oxygen to carry out the metabolic processes. The oxygen molecules help supply energy to the body during circulation. Hence the air exhaled has higher percentage of carbon dioxide than the air inhaled.
