Histology. Episode 3. Glandular Epithelial Tissue

This is a good lesson for the community

Glandular epithelial tissue is a type of epithelial tissue that specializes in the production and secretion of substances. Epithelial tissues are one of the four basic types of animal tissues and are characterized by tightly packed cells with little extracellular matrix. Glandular epithelial tissue is responsible for forming glands, which can be classified into two main types: endocrine glands and exocrine glands.

Endocrine Glands:

These glands release their secretions (hormones) directly into the bloodstream.
Examples include the thyroid gland, adrenal gland, and pituitary gland.
The hormones produced by endocrine glands play a role in regulating various physiological processes.
Exocrine Glands:

These glands release their secretions through ducts that lead to the external environment or a specific organ surface.
Examples include sweat glands, salivary glands, and sebaceous glands.
Exocrine glands produce substances such as sweat, saliva, and digestive enzymes.
The cells in glandular epithelial tissue are specialized to perform secretory functions. These cells often have a high rate of protein synthesis and are equipped with structures like rough endoplasmic reticulum and Golgi apparatus for packaging and releasing secretory products.
