Anatomy & Physiology Respiratory #5

Question

Which structure is excluded when discussing the respiratory system with members of the healthcare team?

Answers

  1. Nose
    • Rationale:

      The nose is a structure of the upper respiratory tract. Therefore, this is an appropriate structure to include in a discussion with members of the healthcare team regarding the respiratory system.

  2. Lungs
    • Rationale:

      The lungs are structures included in the lower respiratory tract. Therefore, this is an appropriate structure to include in a discussion with members of the healthcare team regarding the respiratory system.

  3. Trachea
    • Rationale:

      The trachea is a structure of the lower respiratory tract. Therefore, this is an appropriate structure to include in a discussion with members of the healthcare team regarding the respiratory system.

  4. Esophagus
    • Rationale:

      The esophagus is a structure of the gastrointestinal, not the respiratory system. Therefore, it is not appropriate to include this structure when discussing the respiratory system with other members of the healthcare team.

Overview

The structures of the respiratory system are divided into the upper respiratory tract and the lower respiratory tract. Each tract has specific structures that work together to facilitate respirations.

Explanation

Learning Outcomes

The nose, lungs, and trachea are all structures of the respiratory system.
The esophagus is a structure of the gastrointestinal, not respiratory, system. The epiglottis, a respiratory structure, moves down when drinking fluids and/or swallowing of food to allow the food to enter the esophagus.

Test Taking Tip

Think about the structures included in the upper and lower respiratory tracts when determining the correct answer choice for this question.
