Multiple Choice

How does the muscular system interact with the digestive system to facilitate digestion?

By producing digestive enzymes that break down food.

By regulating the pH levels within the stomach.

By absorbing nutrients from digested food into the bloodstream.

By contracting and relaxing to move food through the digestive tract.

Verified step by step guidance

Understand the role of the muscular system in the digestive process: The muscular system is responsible for the movement of food through the digestive tract via a process called peristalsis.

Identify the types of muscles involved: The digestive system primarily uses smooth muscles, which are involuntary muscles found in the walls of the digestive tract.

Explain peristalsis: Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract, starting from the esophagus and continuing through the stomach, intestines, and finally to the rectum.

Differentiate from other options: The muscular system does not produce digestive enzymes, regulate pH levels, or absorb nutrients. These functions are carried out by other systems and organs such as the pancreas, stomach lining, and intestinal walls.

Conclude with the correct interaction: The muscular system facilitates digestion by contracting and relaxing to move food through the digestive tract, ensuring that it is properly processed and nutrients are absorbed.
