Verified step by step guidance

Understand the role of goblet cells: Goblet cells are specialized epithelial cells found in mucous membranes, such as the respiratory and digestive tracts. Their primary function is to secrete mucus, which lubricates and protects epithelial surfaces.

Understand the role of lacrimal glands: Lacrimal glands are located in the upper outer region of the orbit (eye socket) and are responsible for producing tears. Tears contain water, electrolytes, and proteins that lubricate and protect the surface of the eye.

Compare the functions of goblet cells and lacrimal glands: Both goblet cells and lacrimal glands secrete substances (mucus and tears, respectively) that serve to lubricate and protect epithelial surfaces.

Eliminate incorrect options: Goblet cells and lacrimal glands do not synthesize insulin, produce digestive enzymes, or generate electrical impulses. These functions are performed by other specialized cells or tissues in the body.

Conclude the correct answer: The shared function of goblet cells and lacrimal glands is the secretion of substances that lubricate and protect epithelial surfaces.
