Terms in this Study Set(20)
What is the primary function of the nose?
To filter, warm, and humidify incoming air before it reaches the lungs.
True or false: The pharynx is part of the lower respiratory tract.
False, because the pharynx is considered part of the upper respiratory tract.
Difference between trachea and bronchi?
The trachea is a single airway leading to the bronchi, which branch into the lungs.
What are alveoli?
Tiny air sacs in the lungs where gas exchange occurs, surrounded by capillaries.
Fill in the blank: The _____ connects the larynx to the bronchi.
Trachea
Function of the larynx?
To produce sound and protect the trachea against food aspiration.
What is the role of cilia in the respiratory tract?
To sweep mucus and trapped particles out of the airways.
True or false: The diaphragm is part of the respiratory tract.
False, because it is a muscle that aids in breathing but not part of the airway.
Main gases exchanged in alveoli?
Oxygen is absorbed, and carbon dioxide is released into the lungs.
What is the pleura?
A double-layered membrane surrounding the lungs, providing lubrication.
How does air travel through the respiratory system?
Nose → Pharynx → Larynx → Trachea → Bronchi → Bronchioles → Alveoli.
Which structure prevents food from entering the trachea?
The epiglottis.
What is asthma?
A condition characterized by narrowed airways and difficulty breathing.
Name the two main types of cells in alveoli.
Type I cells (for gas exchange) and Type II cells (produce surfactant).
True or false: The right lung has three lobes.
True, because the right lung is divided into superior, middle, and inferior lobes.
Which is NOT a function of the respiratory system?
Regulating blood glucose levels.
What is the main muscle of respiration?
The diaphragm.
Name the protective mucous membrane lining the nasal cavity.
Respiratory epithelium.
What is ventilation?
The process of moving air in and out of the lungs.
What happens during inspiration?
The diaphragm contracts, expanding the thoracic cavity and drawing air in.
