The stomach secretes _________ to protect its lining from gastric juices.
a. mucus
b. lipase
c. amylase
d. pepsin
Answer is a. mucus. The most abundant epithelial cells are mucous cells, which cover the entire lumenal surface and extend down into the glands as "mucous neck cells". These cells secrete a bicarbonate-rich mucus that coats and lubricates the gastric surface, and serves an important role in protecting the epithelium from acid and other chemical insults.
