The histological structure of a simple branched tubular gland includes several components:
1. Secretory Units: The secretory units are tubular in shape and can be further subdivided into smaller branches. Each tubular unit consists of specialized epithelial cells responsible for secretion.
2. Duct System: The tubular units merge into a single unbranched duct that carries the secretions to the surface or lumen.
3. Epithelial Cells: The epithelial cells lining the secretory units are specialized to produce and secrete various substances such as enzymes, mucus, or hormones.
