Simple cuboidal epithelium is a one-cell layer of cuboidal cells (equal sides) that are found in many glands and ducts and forms “tubes” or ducts.
Exocrine glands have ducts. Endocrine glands do not have ducts.
Secretory epithelial cells that line the resin ducts in pines produce resin made up of resin acids, the essential oil turpentine, resenes ( mixtures of nonvolatile neutral organics) and water.
the two glands that have ducts are the penis and the vagina but they have to meet

Modes of Secretionof exocrine glandsSecretory cells of exocrine glands release their products into ducts in three different ways. The mode of secretion can be classified as merocrine, apocrine, or holocrine.Cells that secrete products via the merocrine method form membrane-bound secretory vesicles internal to the cell. These are moved to the apical surface where the vesicles coalesce with the membrane on the apical surface to release the product. Most glands release their products in this way.In those glands that release product via the apocrinemethod, the apical portions of cells are pinched off and lost during the secretory process. This results in a secretory product that contains a variety of molecular components including those of the membrane. Mammary glands release their products in this manner.The third type of secretory release, holocrine, involves death of the cell. The secretory cell is released and as it breaks apart, the contents of the cell become the secretory product. This mode of secretion results in the most complex secretory product. Some sweat glands located in the axillae, pubic areas, and around the areoli of the breasts release their products in this manner. Sebaceous glands also are of this type.

A simple branched gland has only one duct with more than one are that secretes into that duct. Compound glands have multiple ducts leading into the main duct.
Endocrine glands secrete their hormones directly into the bloodstream. Exocrine glands secrete their hormones into a duct that leaves the body externally: for example, sweat glands empty onto the skin. Endocrine gland secretes compounds (hormones) into the blood. Exocrine gland secretes compounds outside of the body (including into the GI tract since the GI tract is topologically outside of the body). Exocrine glands have ducts that carry their secretory product to a surface. These glands include the sweat, sebaceous, and mammary glands and, the glands that secrete digestive enzymes.The endocrine glands do not have ducts to carry their product to a surface. They are called ductless glands. The word endocrine is derived from the Greek terms "endo," meaning within, and "krine," meaning to separate or secrete. The secretory products of endocrine glands are called hormones and are secreted directly into the blood and then carried throughout the body where they influence only those cells that have receptor sites for that hormone.
endocrine glands are glands without ducts.

Ducts in exocrine glands are used to release its products directly to the target area.
No, sebaceous glands have ducts. They are exocrine glands.
