Respiratory System
Upper Tract

Breathing
100
The respiratory system is made up of these two functional components.
What are the conducting and respiratory parts?
100
These structures collectively form the upper part of the respiratory system.
What are the nose, nasal cavity, pharynx, and larynx?
100
These structures collectively form the lower part of the respiratory system
What are the trachea, lungs, bronchi, bronchioles and alveoli?
100
This membrane covers the lungs
What is the pleura?
100
This is considered the mechanical act of breathing.
What is pulmonary ventilation?
200
This is the place where air is moistened and warmed before entering the respiratory tract
What is the nasal cavity?
200
This structure (#8) is shared by both the digestive and respiratory system.
What is the pharynx?
200
This structure is kept open by C-shaped cartilage and also referred to as the 'windpipe'
What is the trachea?
200
These structures (#4) are the largest passageways in the lungs.
What are the bronchi?
200
This is the passive part of breathing
What is exhalation/expiration?
300
Lining of the nasal cavity that is composed of cilia and goblet cells to help filter and warm air as it enters the respiratory tract.
What is the nasal epithelium?
300
Also known as the voice box, this organ in the throat houses the vocal cords and plays a key role in speech production and preventing food from entering the trachea.
What is the larynx?
300
The lungs are divided into these distinct sections by deep fissures
What are lobes?
300
These tiny air passages in the lungs, branching off from the bronchi, play a crucial role in regulating airflow and ensuring efficient gas exchange.
What are the bronchioles?
300
This muscle is domed-shape and responsible for contraction and relaxation of breathing
What is the diaphragm?
400
This lymphatic tissue is located in the throat, but not actually part of the respiratory system.
What are the tonsils?
400
This automatic response helps clear the airways by forcefully expelling air, mucus, or irritants.
What is the cough?
400
These tiny hair-like structures, found on the surface of respiratory mucosa, play a key role in moving mucus and trapped particles out of the respiratory tract.
What are mucosal cilia?
400
These structures are at the end of the bronchial tree and fill with air for the purpose of gas exchange
What are the alveoli?
400
This gas exchange occurs within the systemic capillaries?
What is internal respiration?
500
This vital function of the respiratory system involves the coordinated action of the lungs, diaphragm, and structures like the larynx, enabling humans to produce speech and various vocalizations
What is sound production?
500
This flap-like structure in the throat prevents food and liquids from entering the windpipe during swallowing.
What is the epiglottis?
500
This thin barrier consisting of the alveolar + capillary walls, is essential for the exchange of oxygen and carbon dioxide.
What is the respiratory membrane?
500
These delicate structures (#6) are responsible for gas exchange between the air in the lungs and the surrounding blood
What are the capillaries?
500
Metabolic reactions generate an excess of this gas, requiring rapid elimination from the body through exhalation.
What is carbon dioxide?
