Respiratory System Anatomy

Front

What is the main function of the trachea?

Back

The trachea, or windpipe, serves as the main airway that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Front

What are alveoli?

Back

Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs.

Front

What role do red blood cells play in the respiratory system?

Back

Red blood cells pick up oxygen from the alveoli and transport it to the body's tissues.

Front

What is the epiglottis and its function?

Back

The epiglottis is a flap of tissue that covers the trachea during swallowing to prevent food and liquid from entering the airway.

Front

What prevents the collapse of the trachea?

Back

The trachea is supported by rings of cartilage that keep it open and prevent collapse.

Front

What is the larynx commonly known as?

Back

The larynx is commonly known as the voice box, as it contains the vocal cords.

Front

What is the primary muscle involved in breathing?

Back

The diaphragm is the primary muscle that contracts and relaxes to facilitate breathing.

Front

What is the function of the bronchi?

Back

The bronchi are the main passageways that branch from the trachea into the lungs, directing air to each lung.

Front

How does oxygen enter the bloodstream?

Back

Oxygen enters the bloodstream through the walls of the alveoli, where it diffuses into the capillaries.

Front

What is the role of the rib cage in respiration?

Back

The rib cage protects the lungs and assists in the mechanics of breathing by expanding and contracting.
