The ____________ in the alveoli is 40 mm Hg and that of the blood entering the pulmonary capillaries is ____________ . This caus
Oxana [17]

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>.

Answer option:

1. duplicate themselves

2. convert energy

3. selectively exchange materials

4. all of the above

Answer:

4. all of the above

Explanation:

Cells carry out many functions. They are able to replicate their DNA and divide into two identical daughter cells in order to proliferate.

They can convert glucose into cellular energy (ATP) through respiration in the mitochondria

They can exchange materials with the outside environment via the selectively permeable cell membrane, endocytosis and exocytosis and active transport via membrane proteins.

Therefore, all of the above is correct.
