Question

Match List-I with List-II: 

List-I (Organ)	List-II (Lining epithelium)
(A) Oesophagus	(I) Transitional
(B) Ureter	(II) Simple squamous
(C) Heart	(III) Stratified squamous
(D) Nasal cavity proper	(IV) Ciliated pseudostratified columnar

Choose the correct answer from the options given below:

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (III), (B) - (I), (C) - (II), (D) - (IV)
• (A) - (I), (B) - (III), (C) - (IV), (D) - (II)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

To quickly match epithelial tissues to their functions:
- High friction (Esophagus) \(\rightarrow\) Stratified squamous (thick protection).
- Stretching (Ureter) \(\rightarrow\) Transitional (flexible).
- Air filtering (Nasal cavity) \(\rightarrow\) Pseudostratified ciliated (sweeping action).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Epithelial tissues line body cavities, organs, and lumens.
The structure of each epithelium is adapted to the specific physiological function of its organ (such as protection, absorption, secretion, or distension).

Step 2: Detailed Explanation:
Let us match each organ with its characteristic lining epithelium:
- (A) Oesophagus: The esophagus experiences mechanical friction during swallowing.
To protect against abrasion, it is lined by stratified squamous epithelium (III). Thus, (A) matches with (III).
- (B) Ureter: The ureter transports urine and must accommodate significant changes in volume.
It is lined by transitional epithelium (urothelium) (I), which can stretch without tearing. Thus, (B) matches with (I).
- (C) Heart: The chambers of the heart (endocardium) are lined by a single layer of flattened endothelial cells.
This is a simple squamous epithelium (II) that provides a smooth surface to prevent blood clotting. Thus, (C) matches with (II).
- (D) Nasal cavity proper: The nasal cavity proper is part of the respiratory system.
It is lined by ciliated pseudostratified columnar epithelium (respiratory epithelium) (IV), which traps and sweeps away foreign particles. Thus, (D) matches with (IV).
This matching sequence gives: (A) - (III), (B) - (I), (C) - (II), (D) - (IV).

Step 3: Final Answer:
The correct match is (A) - (III), (B) - (I), (C) - (II), (D) - (IV). This corresponds to option (B).
