MHT CET · BIOLOGY · STD 12 - 8. Respiration and Circulation
Given below are two statements.
Statement I: Respiratory membrane is composed of two layers of squamous epithelia, each resting on a thick basement membrane.
Statement II: The diffusion of a respiratory gas takes place from lower partial pressure to higher partial pressure of the same.
In the light of above statements, choose the most appropriate answer from the options given below:
- A Both statement I and statement II are cortex
- B Both statement I and statement l are incorrect.
- C Statement I is correct but statement II is incorrect.
- D Statement I is incorrect but statement II is correct.
Answer & Solution
Correct Answer
(B) Both statement I and statement l are incorrect.
Step-by-step Solution
Detailed explanation
The capillary wall is made up of simple squamous epithelium resting on a thin basement membrane. Both the layers have similar structure and are thin walled. Together they make up the respiratory membrane through which gaseous exchange occurs.
