Epithelial and Connective Tissues are essential components of the body, providing structure and support while facilitating specialized functions.
Epithelial tissue consists of sheets of cells that cover body surfaces, line internal surfaces, and form glands. It is highly cellular, with specialized intercellular connections and exhibits polarity. Epithelial tissue is avascular and classified by shape and layers.
Squamous cells are thin and flat, while stratified epithelium consists of multiple layers. Specializations like cilia and microvilli aid in functions such as absorption and movement of substances.
Connective Tissue provides support and structure. Types include adipose, dense, and loose connective tissue, each with specific functions. Cells like fibroblasts and mast cells play essential roles in connective tissue.
