What is the function of goblet cells, which are sometimes found interspersed throughout pseudostratified and simple columnar epithelium?

A) To produce new epithelial cells to replace worn out cells
B) To produce and secrete mucus
C) To provide oxygen to the nearby epithelial cells
D) To absorb nutrients for the epithelial cells
E) To engulf and destroy invading microorganisms

Goblet Cells

Specialized, mucus-producing cells found in the respiratory and intestinal tracts, which help to protect and lubricate the surfaces.

Pseudostratified Epithelium

A type of tissue lining some internal organs and passages, appearing as multiple layers but actually consists of a single layer of irregularly shaped cells.

Simple Columnar Epithelium

A single layer of tall, closely packed cells, aligned in a row, found in areas such as the digestive tract, where they play roles in absorption, secretion, and protection.
