What factor determines the rate of exchange of oxygen between the alveolus and blood capillaries

Biology
1 answer:
Tju [1.3M]2 years ago
4 0

Answer:

The rate of gaseous exchange in alveoli and blood depends on the difference in pressure of gases in both the alveoli and blood capillaries.

Explanation:

The air in alveoli has high pressure of oxygen and low pressure of carbon-dioxide.

The air in blood vessels has high pressure of carbon-dioxide and low pressure of oxygen

Due to the diffusion, the oxygen from alveoli moves towards to blood capillaries and carbon-dioxide diffuses from blood to alveoli.

Hope it helps,

Which of the following are matched correctly?
kogti [31]

Answer:

<u>1. type IV hypersensitivity: delayed-type hypersensitivity.  </u>

<u>2. type I hypersensitivity: IgE  </u>

<u>3. type II hypersensitivity: IgG  </u>

<u>4. type III hypersensitivity: immune complexes </u>

Explanation:

Type IV hypersensitivity is cell mediated hypersensitivity rather than antibodies as in all other types of hypersensitivities. It is also known as delayed type hypersensitivity because it usually respond in 2-3 days via T-Lymphocytes rather than antibodies like IgE or IgG. So we can say that in option 5 is mismatched as it relates type IV to IgG antibodies.
