Question

plz, do it...
Describe, step by step, the journey that carbon dioxide takes from the alveolus out of the body.

Answer 1

Answer:

While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries. Carbon dioxide is brought, through the blood, back to the heart and then to the lungs. Then it is released into the air during exhalation.

Answer 2

Answer:

Air enters your body through your mouth  

and nose.

Air moves down the trachea (windpipe)  

– a large tube.

 

Air moves down a bronchus  

– a smaller tube.

 

Air moves through a bronchiole  

– a tiny tube.

 

Air moves into an alveolus – an air sac.

Oxygen then diffuses into the blood

Explanation:

the written formula for aerobic respiration (using oxygen) is

Glucose + Oxygen =  Carbon Dioxide + Water + Energy
