Glandular epithelia, composed of epithelial tissue, are specialized structures that play a role in the production and release of enzymes Enzymes Enzymes are complex protein biocatalysts that accelerate chemical reactions without being consumed by them. Due to the body's constant metabolic needs, the absence of enzymes would make life unsustainable, as reactions would occur too slowly without these molecules. Basics of Enzymes, hormones Hormones Hormones are messenger molecules that are synthesized in one part of the body and move through the bloodstream to exert specific regulatory effects on another part of the body. Hormones play critical roles in coordinating cellular activities throughout the body in response to the constant changes in both the internal and external environments. Hormones: Overview and Types, sweat, oil, and mucus in organisms. The secretion Secretion Coagulation Studies and release of these substances are prompted by either external or internal stimuli. Products of glandular epithelia are released either into ducts leading to the surface of the epithelium Epithelium The epithelium is a complex of specialized cellular organizations arranged into sheets and lining cavities and covering the surfaces of the body. The cells exhibit polarity, having an apical and a basal pole. Structures important for the epithelial integrity and function involve the basement membrane, the semipermeable sheet on which the cells rest, and interdigitations, as well as cellular junctions. Surface Epithelium: Histology or into the blood. The 2 types of glands are exocrine and endocrine glands. The classification is based on the number and location of secreting cells and the type of secretions, among other factors.
