1. **Glandular Epithelium Definition:** Glandular epithelium refers to specialized epithelial cells that function as glands, secreting bodily products. These glands can be found within endocrine glands, which are ductless and release hormones directly into the bloodstream[1][9].

2. **Endocrine Glands:** Endocrine glands, a type of glandular epithelium, secrete hormones like those from the pituitary gland (base of the brain), thyroid gland (neck), and adrenal glands (on top of the kidneys)[1][3][6].

3. **Ductless Nature:** Unlike exocrine glands that have ducts, endocrine glands release their secretions (hormones) directly into the blood, allowing hormones to act over long distances[3][8].

In summary, glandular epithelium within endocrine glands plays a vital role in hormone secretion directly into the bloodstream, regulating various physiological processes[1][3][9].
