Which one of the following is incorrect regarding compound epithelium ?

Options

A. Multi - layered with no stretchability.
B. Cover the moist surface of buccal cavity and pharynz.
C. Provide protection against chemical and mechanical stress.
D. They play a vital role in secretion and absorption.

Answer

To determine which statement is incorrect regarding compound epithelium, we will analyze each option provided in the question.

### Step 1: Analyze the first statement
**Statement:** Compound epithelium is multi-layered with no stretchability.
**Analysis:** This statement is correct. Compound epithelium consists of multiple layers of cells and does not have the ability to stretch, which is a characteristic of stratified epithelium.

### Step 2: Analyze the second statement
**Statement:** Compound epithelium covers the moist surface of the buccal cavity and pancreas.
**Analysis:** This statement is also correct. Compound epithelium is found in areas that require protection, such as the moist surfaces of the buccal cavity and other similar locations.

### Step 3: Analyze the third statement
**Statement:** Compound epithelium provides protection against chemical and mechanical stress.
**Analysis:** This statement is correct as well. The primary function of compound epithelium is to provide a protective barrier against various types of stress, including chemical and mechanical.

### Step 4: Analyze the fourth statement
**Statement:** Compound epithelium plays a vital role in secretion and absorption.
**Analysis:** This statement is incorrect. Compound epithelium does not primarily function in secretion and absorption; rather, it serves protective functions. The roles of secretion and absorption are typically associated with cuboidal and columnar epithelium.

### Conclusion
The statement that is incorrect regarding compound epithelium is: **"They play a vital role in secretion and absorption."**
