'''Ductless glands''' are [[gland]]s that secrete their product directly onto a surface rather than through a duct. Examples are the [[goblet cell]]s in the [[Epithelium|epithelial]] surface of the digestive, respiratory, urinary and reproductive systems. Many [[endocrine gland]]s are also ductless glands, as they secrete the hormones they produce directly into the blood or lymph system so it will be circulated to the entire body. The [[pineal gland]], the [[thymus|thymus gland]], the [[pituitary gland]], the [[thyroid|thyroid gland]], the [[spleen]], and the two [[adrenal gland]]s are all ductless glands.
