Verified step by step guidance

Understand the characteristics of epithelial tissue: Epithelial tissue is composed of tightly packed cells that form continuous sheets. These cells are specialized to cover and line body surfaces, such as the skin, the lining of the digestive tract, and the respiratory system.

Compare epithelial tissue to other tissue types: Nervous tissue is specialized for communication and signal transmission, muscle tissue is specialized for contraction and movement, and connective tissue provides structural support and connects other tissues. None of these have the characteristic of forming continuous sheets to line surfaces.

Recognize the functional role of epithelial tissue: Epithelial tissue serves as a protective barrier, controls permeability, and may be involved in secretion, absorption, or sensation depending on its location and type.

Identify examples of epithelial tissue in the body: Examples include the epidermis of the skin, the lining of the intestines, and the alveoli in the lungs. These structures are all lined by epithelial cells.

Conclude that epithelial tissue is the correct answer based on its defining characteristics and functions, which match the description provided in the problem.
