Answer:
The <u>PCO₂</u> -carbon dioxide partial pressure- in the alveoli is 40 mm Hg and that of the blood entering the pulmonary capillaries is <u>45 mmHg</u>. This causes <u>carbon dioxide</u> to diffuse down its partial pressure gradient from the blood into the alveoli.
Explanation:
Gas exchange is a physiological process that involves the entry of oxygen into the body and tissues and the exit of carbon dioxide, a product of metabolic reactions.
At the pulmonary level, gas exchange occurs between the alveoli and the alveolar capillary, and the diffusion of gases across the alveolar-capillary barrier is dependent on a pressure gradient due to the partial pressure of gases.
In the case of CO₂ the diffusion goes from where the partial pressure is higher to where it is lower, i.e. <u>from the alveolar capillary, where the PCO₂ is 45 mmHg, to the pulmonary alveolus, where the PCO₂ is 40 mmHg</u>.

Subordinate clause I just took test
Ribosomes - Make protein
Golgi Apparatus - Make, process, and package proteins
Nucleus - Stores the DNA and coordinates the cell's activities
Mitochondria - Make energy out of food
Vacuole - Storage for food and water
Lysosome - Contains digestive enzymes that help break down food
Plant cells (only) -
Cell wall - Protection and support
Chloroplast - Uses sunlight to create food using photosynthesis
I hope this helps :)
The nervous system, i could be wrong.
