Question 21

What is the main function of the respiratory system?

Answer 21

To bring oxygen to all cells of the body and to remove carbon dioxide waste.

Question 22

What is required in order for the body to properly externally and respirate?

Answer 22

1. A respiratory surface large enough for gas exchange to occur quickly.
2. A moisture lining (water) for gases to dissolve

Question 23

What is external respiration?

Answer 23

Exchange of oxygen and carbon dioxide between the air in the lungs and the blood.

Question 24

What is internal respiration?

Answer 24

Exchange of oxygen and carbon dioxide between the blood in the capillaries and the tissue cells.

Question 25

Where are the gases exchanged in external respiration?

Answer 25

They are exchanged between the alveoli and the blood in the capillaries.

Question 26

What are alveoli?

Answer 26

Very small air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

Question 27

What are capillaries?

Answer 27

The smallest form of blood vessel.

Question 28

In external respiration does the alveoli or the air inside of the lungs have a higher concentration of oxygen? WHY?

Answer 28

the air has a higher oxygen concentration. It needs to be for diffusion to work.

Question 29

30% of oxygen transfer in external respiration occurs through what process?

Answer 29

Facilitated diffusion.

Question 30

What carries oxygen across the alveoli membrane?

Answer 30

Protein-based molecules.

Question 31

Does external respiration need energy?

Answer 31

No, because it works through diffusion.

Question 32

In external respiration does the air or the alveoli have a higher carbon dioxide concentration? WHY?

Answer 32

Alveoli because it needs to have a higher concentration to transfer into the air through diffusion.

Answer 37

The opening for the windpipe.

Question 38

What is the function of the larynx?
