__________ are water-soluble, complex glycoproteins that are secreted by goblet cells. Hormones Amino acids Salts Enzymes Mucins
OleMash [197]

Answer:

Globlet cells  are found in  the epithelial cells on  the  walls of  trachea, bronchi, and villi and Fallopian tube.  They are unicellular  exocrine glands(  ductless glands,do not secret hormones  directly into the blood streams) which are columnar in shape, that is they are shaped like columns.

They function in secretions of Mucus containing MUCIN. The mucus lubricates the surrounding mucus membrane  medium they are located. Mucin is the main  major components of the mucus, and it is  is jelly-like in nature.( Thus jelly-like nature of mucus is  due to MUCIN contents. ) Glyco-protein(glycogen +protein; glycogen attachments to polypeptide chains), is its  chemical components.The glyco-protein is produced by Carbohydrates.

Apart from the lubricating role, the mucus through the mucin it contains  traps any foreign substances that is found in the passage they are deposited, and sweep them.Their jelly-like nature facilitated the trapping.For example in the bronchioles , trachea, and the female genitalia tracts,  they traps bacteria and fungi with the  mucus and clear with cillia.
