Question

The tissue, which is composed of columnar, ciliated cell that line body cavities is

• A. Connective tissue
• B. Adipose tissue
• C. Epithelial tissue
• D. Muscular tissue

Answer 1

The correct option is C

Epithelial tissue

The correct option is C:

Explanation of correct option:

1. The tissue which forms the outer covering of the skin and also the lining of the cavities is known as Epithelial tissues.
2. They form the lining onto the surface of the respiratory, excretory, digestive, and reproductive tract.
3. As they cover the complete body, so they become the first line of defense against any injury and infection.
4. They perform the functions of secretion, absorption, and exchange of materials.
5. There are three types of epithelial tissues, which are classified on the basis of their shape, number of layers, and functions.
6. Squamous Epithelium (thin and flat cells), Cuboidal Epithelium (short cylindrical cells), and Columnar Epithelium (long or column-like cylindrical cells).

Explanation of incorrect option:

Option A:

1. Connective tissue is composed of three components such as fibers, cells, and intracellular medium.
2. They lie wide apart in intracellular or extracellular material.

Option B:

1. Adipose tissue is one of the types of connective tissue.
2. They are the modified form of areolar tissue containing large fat cells.
3. They are found in subcutaneous layers; pads around certain internal organs.
4. Their main function is to store the food and insulation and give support to the organs like kidneys and mammary glands.

Option C:

1. Muscular cells are composed of the specified elongated and thin cells called muscle fibers.
2. The special property of muscular tissue is contractility.
3. There are three types of muscular tissues; Striated, non-striated, and cardiac muscle.

Final Answer: Thus, the tissue, which is composed of columnar, ciliated cells that line body cavities, is Epithelial tissue.
