4.2 Epithelial Tissue – Anatomy & Physiology
Epithelial tissue primarily appears as large sheets of cells covering all surfaces of the body exposed to the external environment and lining internal body cavities. In addition, epithelial tissue is responsible for forming a majority of glandular tissue found in the human body. Epithelial tissue is derived from all three major embryonic layers.

Oct 04, 2019·Epithelial tissues play the role of separating two structures from each other. For instance, the epithelium in a blood vessel demarcates the cells of the blood from those forming the artery or vein. This allows two organs to remain in close proximity for their function while maintaining separate internal physiology.
