Gas exchange involves the transport of two respiratory gases, oxygen and carbon dioxide. Review how each gas is transported between the atmosphere and the cells of your body by completing this exercise.1. required for cellular respiration 2. net diffusion from alveoli to lung capillaries3. sometimes transported as bicarbonate
4. net diffusion from body tissues to blood
5. net diffusion from lung capillaries to alveoli
6. waste product of cellular respiration7. enters alveoli during inhalation
8. transported by hemoglobinA. Oxygen onlyB. Carbon Dioxide OnlyC. Both Oxygen and carbon dioxide

When we breathe, we inhale oxygen and we exhale carbon dioxide.    

Explanation:

1. For the cellular respiration, the body cells are provided with oxygen during gas exchange in respiration.

2. Oxygen gas diffuses from alveoli to the capillaries in our lungs.

3. Carbon dioxide is always transported in plasma or bounded to the hemoglobin or in some form of bicarbonate.

4. Carbon dioxide gas diffuses from our body tissues to the blood.

5. In our lungs, carbon dioxide gas diffuses from capillaries in to alveoli. Carbon dioxide leaves the body when we exhale.

6. During cellular respiration, we give give out and removes carbon dioxide from our body which is a waste product.

7. When we inhale, both oxygen and carbon dioxide gases enters the alveoli,

8. All the oxygen present in blood is bounded by hemoglobin and it is carried to all the body tissues and body and diffuses from our blood to our body tissues.
