Figure 33.11 Which of the following statements about types of epithelial cells is false?
- Simple columnar epithelial cells line the tissue of the lung.
Introduction:
Epithelial cells are present on the linings of various organs of the body. Their functions include protection, absorption, diffusion, transport, and secretion.
Answer to Problem 1VCQ
Correct answer:
The correct answer is option (a).
Explanation of Solution
Explanation for the correct answer:
Option (a) is given as simple columnar epithelial cells lining tissue of the lungs. However squamous epithelial tissue is present in the lining of the lungs to allow easy diffusion air. Hence, option (a) is correct.
Explanation for the incorrect options:
Option (b) is given as simple cuboidal epithelial cells are involved in the filtering of blood in the kidney. Cuboidal epithelial cells provide a larger surface area for absorption in the kidneys. Hence, option (b) is incorrect.
Option (c) is given as pseudostratified columnar epithelia occur in a single layer, but the arrangement of nuclei makes it appear that more than one layer is present. The statement is true as the cells have multiple nuclei, which are present in parallel lines and pseudostratified columnar epithelia appear like multicellular. Hence, option (c) is incorrect.
Option (d) is given as transitional epithelia change in thickness depending on how full the bladder is. The statement is correct as transitional epithalamia are flexible and present in bladder and ureter. Hence, option (c) is incorrect.
Squamous epithelia consist of a single layer of thin-walled cells that are present in the lining of the lungs to allow the diffusion of gases.
