Epithelial Duct -

: Delivering enzymes (pancreas), hormones, or waste (kidneys).

The cellular architecture of a duct is specialized based on its location and function: epithelial duct

: Larger ducts, such as those in the breast or sweat glands, often feature stratified cuboidal or columnar epithelium to provide structural durability. 1. Structure and Tissue Type

: Ensuring clear separation between luminal contents and the body's interstitium. 3. Developmental Morphogenesis : Delivering enzymes (pancreas)

: Cells within the duct (e.g., in salivary glands) can actively modify the ion concentration or pH of the fluid they transport.

An is a tubular structure lined by epithelial cells that serves as a conduit for the transport of secretions (like sweat, saliva, or milk) or fluids (like urine) from glands or organs to their destination. 1. Structure and Tissue Type
