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.
