Question

Secretion of isolated glandular cells called goblet

cells of alimentary canal is
​

Answer 1

Answer:

Some of the columnar or cuboidal cells get specialised for secretion and are called glandular epithelium (Figure 7.2). They are mainly of two types: unicellular, consisting of isolated glandular cells (goblet cells of the alimentary canal), and multicellular, consisting of cluster of cells (salivary gland).

Answer 2

Answer:

Notice that the epithelium is in direct contact with the lumen, the space inside the alimentary canal. Interspersed among its epithelial cells are goblet cells, which secrete mucus and fluid into the lumen, and enteroendocrine cells, which secrete hormones into the interstitial spaces between cells.
