Verified step by step guidance

Understand the role of goblet cells in the body. Goblet cells are specialized epithelial cells found in the lining of organs such as the intestines and respiratory tract.

Recognize that goblet cells are primarily responsible for secreting mucus. Mucus is a viscous fluid that serves several important functions.

Consider the function of mucus in the body. Mucus acts as a lubricant and protective barrier for the epithelium, preventing damage from pathogens and mechanical stress.

Differentiate between the functions listed in the problem. Goblet cells do not produce hormones or absorb wastes; these functions are performed by other types of cells.

Conclude that the primary function of goblet cells is to secrete mucus, which lubricates and protects the epithelium.
