Verified step by step guidance
1
Understand the primary functions of epithelial tissue. Epithelial tissue serves several key roles in the body, including protection, secretion, absorption, and filtration.
Consider the role of protection. Epithelial tissue forms a protective barrier against physical and chemical injury, which is a fundamental function.
Evaluate the function of secretion. Epithelial cells are involved in the secretion of hormones and enzymes, contributing to various physiological processes.
Assess the absorption function. Epithelial tissue is responsible for the absorption of nutrients, particularly in the digestive tract.
Identify the function that is not typical of epithelial tissue. Conduction of electrical impulses is primarily a function of nervous tissue, not epithelial tissue.
