What is the basic mechanism by which air travels to the alveoli for gas​ exchange? emt?

Biology
1 answer:
Anestetic [448]3 years ago
6 0
The Major function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli, the layers of the cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other, the barrier between air and blood averages about 1 micron in thickness. Oxygen diffuses quickly through the air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.

Hello!

your answer is A.  How much energy is used to make one paper bag?

the word "should" is a giveaway of B, C, and D being questions for personal opinions. everyone has different views on what SHOULD be, so if you asked 100 people, chances are you'd get many different answers.

A can only have one possible answer.

(I don't know the answer to how much energy is used to make one paper bag so let's just leave it at that, shall we?)

I hope this helps, and have a nice day!
