Respiratory System Overview

Which of the following is NOT a part of the upper respiratory tract?

Which component is part of the lower respiratory tract?

What is the function of the diaphragm in the respiratory system?

Which of the following correctly lists components of the lower respiratory tract?

Which part of the respiratory system is primarily responsible for gas exchange?

Upper Respiratory Tract

The nose and nasal cavity are the entry point for air into the respiratory system.
The mouth or oral cavity, also known as the buccal cavity, can serve as an alternate pathway for air intake.
The pharynx, commonly called the throat, is a muscular tube connecting the nasal cavity and mouth to the larynx.
The larynx, also called the voice box, is a cartilaginous structure that helps produce sound and regulates airflow to and from the lungs.

Lower Respiratory Tract

The trachea, also known as the windpipe, is a long, flexible tube that carries air from the larynx to the lungs.
The bronchi are the two main branches of the trachea that further divide into smaller tubes called bronchioles.
The bronchioles lead to the alveoli, which are tiny air sacs in the lungs where oxygen exchange takes place.
The diaphragm is a dome-shaped muscle that plays a crucial role in breathing by contracting and relaxing to change the volume of the chest cavity.
The lungs are paired organs responsible for gas exchange, taking in oxygen and releasing carbon dioxide.

Explore the structure and function of the upper and lower respiratory tracts in this quiz. You'll learn about components such as the nose, larynx, trachea, and alveoli, discovering how they work together for breathing and sound production.
