Note the following
(A) It forms the lining of the cavities of
alveoli of the lungs
(B) it forms the lining of wet surfaces like
buccal cavity and oesophagus
(C) it occurs in the ducts of sweat glands
(D) it forms the lining of salivary glands and
sweat glands
(E) it is a loose connetive tissue
Which of the above are associated with simple epithelial tissue ?

Options

A. A and D
B. B and C
C. C and A
D. D and E

Answer

To determine which of the statements are associated with simple epithelial tissue, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement A**: "It forms the lining of the cavities of alveoli of the lungs."
- **Analysis**: The alveoli are lined by simple squamous epithelium, specifically by cells known as pneumocytes. Therefore, this statement is associated with simple epithelial tissue.
- **Conclusion**: **True** (associated with simple epithelial tissue).

2. **Statement B**: "It forms the lining of wet surfaces like buccal cavity and oesophagus."
- **Analysis**: The buccal cavity and oesophagus are lined by stratified squamous epithelium, which is not a simple epithelium. Therefore, this statement is not associated with simple epithelial tissue.
- **Conclusion**: **False** (not associated with simple epithelial tissue).

3. **Statement C**: "It occurs in the ducts of sweat glands."
- **Analysis**: The ducts of sweat glands are lined by stratified cuboidal epithelium, which is also not a simple epithelium. Therefore, this statement is not associated with simple epithelial tissue.
- **Conclusion**: **False** (not associated with simple epithelial tissue).

4. **Statement D**: "It forms the lining of salivary glands and sweat glands."
- **Analysis**: The salivary glands are lined by simple cuboidal epithelium, which is a type of simple epithelial tissue. However, sweat glands have ducts lined by stratified cuboidal epithelium. Since this statement mentions both, it is partially true but primarily refers to simple cuboidal epithelium.
- **Conclusion**: **True** (associated with simple epithelial tissue).

5. **Statement E**: "It is a loose connective tissue."
- **Analysis**: Loose connective tissue is not an epithelial tissue; it is a type of connective tissue. Therefore, this statement is not associated with simple epithelial tissue.
- **Conclusion**: **False** (not associated with simple epithelial tissue).

### Final Answer:
The statements associated with simple epithelial tissue are **A and D**.
