Verified step by step guidance

Understand the definition and characteristics of epithelial tissue: Epithelial tissue is a type of tissue that lines the surfaces and cavities of organs and structures throughout the body. It serves functions such as protection, absorption, secretion, and filtration.

Clarify the term 'avascular but innervated': Epithelial tissue lacks blood vessels (avascular), meaning it does not have a direct blood supply. However, it is innervated, meaning it has nerve endings that allow for sensation.

Evaluate the first statement: 'Epithelial tissue is found only in the heart.' This is incorrect because epithelial tissue is found throughout the body, not just in the heart. It lines organs, blood vessels, and body cavities.

Evaluate the second statement: 'Epithelial tissue is primarily responsible for voluntary movement.' This is incorrect because voluntary movement is controlled by skeletal muscle tissue, not epithelial tissue.

Evaluate the fourth statement: 'Epithelial tissue contains abundant blood vessels.' This is incorrect because epithelial tissue is avascular, meaning it does not contain blood vessels. Nutrients are supplied to epithelial cells via diffusion from underlying connective tissues.
