Question

why exhaled gas more than inhaled gas​

Answer 1

Answer:

When the air reaches our lungs the oxygen is absorbed into the blood via the alveoli, popcorn-shaped air sacs, which allow for oxygen transfer to blood in the capillaries. ... The expelled CO2 is then exhaled and this is why our exhaled air has more CO2 than inhaled air.

Answer 2

Answer:

more oxygen used to create energy

less carbon dioxide than…

Exhaled air which contains:

more carbon dioxide produced as a waste product of energy production

less oxygen as it has been used in respiration

Gas exchange takes place by diffusion in the alveoli within the lungs. As a result the composition of inhaled and exhaled air is different.
