Question

in the human digestive system, the stomach, pancreas, and intestines work together. which of the following is an example of a tissue in the digestive system?
a. the stomach
b. smooth muscle that lines the stomach
c. nerve cells in the stomach

Explanation:

• Option A: The stomach is an organ, not a tissue. Organs are made up of different types of tissues working together.
• Option B: Smooth muscle is a type of tissue. Tissues are groups of similar cells that perform a specific function. Smooth muscle tissue that lines the stomach helps in the contraction and relaxation of the stomach for digestion.
• Option C: Nerve cells in the stomach are part of nervous tissue. But the question asks for a tissue example in the digestive system related to the stomach's structure - and smooth muscle (a tissue type) that lines the stomach is a more direct answer as it's a tissue component of the stomach's wall structure for its function (like churning food).

Answer:

B. Smooth muscle that lines the stomach
