Upper Respiratory
These structures are in the upper respiratory system.
What are the nose, nasal cavity, pharynx, and larynx?
These structures are part of the lower respiratory system.
What are the trachea, bronchi, bronchioles, alveolar ducts, and alveoli?
This occurs at the alveoli on the cellular level.
What is the exchange of oxygen gas and carbon dioxide?
Bacterial and viral infections cause fluid buildup in the lungs, leading to painful coughs, fever, and difficulty breathing.
What is pneumonia?
In functional organization, these are the two main zones of the respiratory system.
What are the conduction zone and the respiratory zone?
This substance is secreted by goblet cells and helps humidify incoming air in the nose and traps microbes.
What is mucus?
The epiglottis ensures food and liquids do not enter this structure.
What is the trachea?
There are this many alveolar sacs in the lungs.
What are 300 to 400 million?
This condition causes bronchoconstriction, leading to difficulty breathing, due to certain triggers.
What is asthma?
This type of muscle relaxation allows more air to enter the lungs.
What is bronchodilation?
These receptors in the nasal cavity detect odors.
What are the olfactory receptors?
What are the main bronchi, the lobar bronchi, the segmental bronchi, the terminal bronchioles, the respiratory bronchioles, and the alveoli?
A mesh of these vessels surround each alveolus, allowing gases to enter and exit the circulatory system.
What are the capillaries?
Known officially as rhinorrhea, this condition occurs due to an overproduction of mucus in the nasal cavity or secretions of the lacrimal glands.
What is a runny nose?
These sections of each lobe are autonomous units which are encapsulated by connective tissues and supplied by its own artery, vein, and lymph vessels.
What are the bronchopulmonary segments?
These are the three sections of the pharynx.
What are the nasopharynx, oropharynx, and laryngopharynx?
This non-respiratory structure causes the left lung to have two lobes, whereas the right lung as three lobes.
What is the heart?
This thin barrer of 0.5 microns separate the air in the alveoli from the capillaries, allowing for gases to diffuse into the blood.
What is the respiratory membrane?
Nosebleeds, or epistaxis, occur in this region of the nasal cavity.
What is the respiratory region?
This machine helps deliver a fine, steady mist of medicine through a mouthpiece or mask.
What is a nebulizer?
The vocal folds create your voice. The vestibular folds do this.
What is protect the vocal folds?
This muscle contractions during inspiration and relaxes during expiration.
What is the diaphragm?
Alveolar type II cells secret this substance, coating the inside of the alveolus and preventing collapse and sticking during breathing.
A lack of chloride ions causes a thick buildup of mucus in the respiratory system due to a failure to properly hydrate the surface of cells.
What is cystic fibrosis?
Of the three lung surfaces, this surface is adjacent to the ribs.
What is the costal surface?
