Respiratory System

Front

What is the primary function of the respiratory system?

Back

To facilitate gas exchange, providing oxygen to the body and removing carbon dioxide.

Front

Define gas exchange in the context of the respiratory system.

Back

The process by which oxygen is taken into the body and carbon dioxide is expelled, primarily occurring in the alveoli.

Front

What are alveoli?

Back

Tiny air sacs in the lungs where gas exchange occurs.

Front

Explain the role of the diaphragm in respiration.

Back

The diaphragm is a muscle that contracts and relaxes to help draw air into the lungs during inhalation and push air out during exhalation.

Front

What is the pathway of air during inhalation?

Back

Nasal cavity → Pharynx → Larynx → Trachea → Bronchi → Bronchioles → Alveoli.

Front

What is asthma?

Back

A common respiratory disorder characterized by inflamed airways, leading to difficulty breathing.

Front

What is the difference between the conducting and respiratory zones of the respiratory system?

Back

The conducting zone includes structures that transport air (e.g., trachea, bronchi), while the respiratory zone is where gas exchange occurs (e.g., alveoli).

Front

What is the role of the trachea in the respiratory system?

Back

The trachea, or windpipe, is a tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Front

Define simple diffusion in the context of gas exchange.

Back

The movement of oxygen and carbon dioxide across the respiratory membrane from areas of higher concentration to lower concentration.

Front

What are bronchi?

Back

The main passageways that branch from the trachea into the lungs, leading to smaller bronchioles.
