What Functions Does Simple Columnar Epithelium Serve?
Simple columnar epithelium is involved in several key functions:
Absorption: In the intestines, these cells are responsible for absorbing nutrients from digested food. Secretion: The cells can secrete digestive enzymes and mucus. Goblet cells, in particular, secrete mucus to lubricate the epithelial surface. Protection: The mucus secreted by goblet cells protects the lining of the digestive tract from acidic and enzymatic damage.
