Transcribed Image Text:### Understanding Muscle Types in the Digestive System
#### Question:
"Given what you know about the functions of each muscle type, which one would be associated with the small intestine to help move chyme through the digestive system?"
#### Options:
- Cardiac muscle
- Smooth muscle
- Skeletal (striated) muscle
#### Explanation:
To process this question, you need to consider the primary function and location of each muscle type within the human body.
1. **Cardiac Muscle**: This type of muscle is found in the heart. It is responsible for pumping blood throughout the body. It has an involuntary rhythmic contraction but is not involved in the digestive system.
2. **Smooth Muscle**: Smooth muscle is found within the walls of hollow organs like the intestines, blood vessels, and the bladder. Unlike skeletal muscle, smooth muscle is not under voluntary control. In the digestive system, smooth muscle in the walls of the intestines performs peristalsis—the wave-like contractions that move food and chyme through the digestive tract.
3. **Skeletal (Striated) Muscle**: This type of muscle is connected to the skeleton and is used for voluntary movements of the body. Skeletal muscle is under conscious control and is not involved in the involuntary contractions necessary to move chyme in the digestive tract.
Given the context of the small intestine and the process of moving chyme through the digestive system, the **correct answer** is **Smooth muscle**.
