Describe how oxygen and carbon dioxide are transported in the blood, and explain how their loading and unloading is affected by temperature, pH, BPG and PCO2

Describe how oxygen and carbon dioxide are transported in the blood, and explain how their loading and unloading is affected by temperature, pH, BPG, and PCO2.

Match each statement with the appropriate category depending onwhether it applies to oxygen only, carbon dioxide only, or bothoxygen and carbon dioxide.

Statements: -waste product of cellular respiration
- net diffusion from lung capillaries to alveoli
- net diffusion from body tissues to blood
- required for cellular respiration
- transported by hemoglobin
- net diffusion from alveoli to lung capillaries
- sometimes transported as bicarbonate
- enters alveoli during inhalation
categories
Oxygen only:
Carbon dioxide only:
Both oxygen and carbon dioxide

Please help

1. Describe the transport of oxygen from an alveolus to a respiring cell and the movement of carbon dioxide from a cell to the air in an alveolus include the directions of diffusion for oxygen and carbon dioxide in an alveolus and in the blood plasma near respiring cell.

2. Compare blood flow through an artery and a vein and relate the flow characteristics to the structures of these blood vessels
