Which type of tissue lines your internal organs?
Correct answer: C. Epithelial
- A. Connective
- B. Muscle
- C. Epithelial
- D. Spongy
Explanation
Epithelial tissue primarily lines surfaces exposed to the external environment or internal cavities with direct openings to the outside. Internal organs are typically surrounded by connective tissue and are not directly exposed to the external environment, thus they don't require a lining of epithelial tissue. Instead, the epithelium serves as a protective barrier for surfaces where absorption, secretion, and exchange of substances occur. Therefore, organs are often encapsulated within the body and do not necessitate direct epithelial lining.
