Three types of glands are associated with the digestive tract. These are unicellular mucous glands present in the mucosa, multicellular glands present in the mucosa and submucosa, multicellular glands present outside the digestive tract.

Answer to Problem 1RAC

The correct answer is option (a) mucosa.

Explanation of Solution

Option (a) mucosa. The mucosa is the inner tunic of the digestive tract, and it surrounds the lumen of the digestive tract. Therefore, the mucosa is in direct contact with ingested substances. So, the correct answer is option (a).

Explanation for incorrect answer:

Option (b) muscularis. It is the middle tunic of the digestive tract and does not come in contact with the lumen. Hence, the given option is not correct.

Option (c) serosa. It is the external layer of the mucosa. It does not interact with food substances. Hence, the given option is not correct.

Option (d) submucosa. It is present next to the mucosa and does not connect with the lumen of the digestive tract. Hence, the given option is not correct.
