Which of the following are characteristics of epithelial tissue?

• A. Avascularity and high regenerative capacity
• B. Presence of striations and voluntary control
• C. Rich blood supply and low regenerative capacity
• D. Ability to contract and generate force

Answer: (A)

Verified step by step guidance

1. Understand the basic characteristics of epithelial tissue. Epithelial tissue is known for covering surfaces and lining cavities, and it serves as a protective barrier.
2. Recognize that epithelial tissue is avascular, meaning it does not contain blood vessels. Nutrients and waste exchange occur through diffusion from underlying tissues.
3. Identify the high regenerative capacity of epithelial tissue. This means epithelial cells can rapidly divide and replace damaged or dead cells, maintaining the integrity of the tissue.
4. Differentiate epithelial tissue from muscle tissue, which has striations and voluntary control, and is capable of contraction and generating force.
5. Consider the options given: Avascularity and high regenerative capacity are correct characteristics of epithelial tissue, while the other options describe features of muscle tissue or other types of tissues.
