Anatomy & Physiology Gastrointestinal #15

Question

Which long, straight hollow structure of the gastrointestinal (GI) tract connects the pharynx with the stomach?

Answers

1. Urethra
   • Rationale:

     While the urethra is a hollow structure that transports urine for the urinary tract, it does not connect the pharynx with the stomach.

2. Bladder
   • Rationale:

     The bladder is a hollow structure that holds urine for the urinary tract. It does not connect the pharynx with the stomach.

3. Intestine
   • Rationale:

     While the intestine is a structure in the GI tract, it does not connect the pharynx with the stomach.

4. Esophagus
   • Rationale:

     The esophagus is the long, straight, and hollow structure that connects the pharynx to the stomach. It is lined with smooth muscle that moves fluids and food to the stomach via peristalsis.

Overview

The GI tract includes the organs and structures that are responsible for the digestive process.

Explanation

Learning Outcomes

Food and fluids travel a specific pathway through the GI tract. This pathway begins in the mouth and ends at the rectum. The esophagus connects the pharynx (i.e., throat) to the stomach.

Test Taking Tip

Consider the location and function of each structure to answer this question correctly.
