Name the secretory cells which are common to both, small intestine and large intestin

The secretory cells that are common to both the small intestine and large intestine are primarily goblet cells. Goblet cells are specialized epithelial cells that are responsible for the secretion of mucus. This mucus plays a crucial role in lubricating the intestinal lining to facilitate the passage of food and protect the intestinal walls from digestive enzymes and mechanical damage.

In addition to goblet cells, both intestines also contain enteroendocrine cells, which secrete hormones that help regulate digestive processes. These include secretin, cholecystokinin (CCK), and others that are important for digestive function.

Together, these cells contribute to the overall function of the intestines in the digestion and absorption of nutrients as well as the preparation for waste excretion.
