Question

The picture represents gas exchange in the alveoli. Observe what is happening at location X. What will happen with the CO2 next?

Answer 1

Answer:

please attach the picture so I could see where the X is

But as I guess roughly where the X is CO2 will then diffuse into the air in the lungs (alveoli) from blood

hope this helps you

Answer 2

Answer:

The gas exchange actual occur at alveolar level .It is the actual part from where exchange  of oxygen and carbon dioxide occurs between blood and air-sacs .

Explanation:

1. The respiratory system consist of nostrils ,nasal cavity , pharynx ,larynx Trachea ,Bronchi which divides into two and enters the lungs where it further forms more finer vessels called as Bronchi-oles which finally leads to into alveoli  .
2. All the organs mentioned above except alveoli is a part of respiratory passage .
3. The alveoli is surrounded with tuft of capillaries .
4. The oxygen via respiratory tract enters the passage and finally reaches alveoli .
5. The concentration of oxygen is more in inhaled air therefore ,it diffuses into Blood from where it is carried to all tissues and cells .
6. The cells have more concentration of carbon-dioxide therefore ,it diffuses into blood and through blood to alveoli and finally exhaled out .
