Diseases
The flu is this type of disease which can be spread through droplets made by coughing, sneezing, or talking.
What is airborne?
This is the most important muscle used in respiration
What is the diaphragm?
Commonly called the Adam's apple, this is one piece of cartilage the larynx is composed of
What is the thyroid cartilage?
These structures that branch off from the bronchi and subdivide into alveolar ducts are made of smooth muscle
What are bronchioles?
After entering through the nose, air flows here, which is separated by the septum
What is the nasal cavity
Characteristic of emphysema caused by trapped carbon dioxide in the alveoli
What is barrel chest?
The contraction of the diaphragm causes this form of respiration
What is inspiration?
This part of the nose is also a part of the nervous system and is responsible for sense of smell
What are olfactory receptors?
The left lung is smaller than the right due to this vital organ
What is the heart?
As air leaves the nose, it enters this structure, which contains the vocal cords and is commonly called the voice box
What is the larynx?
This is a respiratory disorder caused by a sensitivity to an allergen, stress, overexertion, or infection in which the openings of the bronchioles narrow
What is asthma?
This form of respiration is the exchange of gases between the lungs and the bloodstream
What is external respiration?
These are conchae bones that divide the nasal cavity into three narrow passageways to increase the surface area of the cavity, causing air to move in various directions
What are turbinates?
This structure is supported by rings of cartilage that help prevent collapsing
What is the trachea?
These structures carry air form the trachea to the lung
What are bronchi?
TB is caused by this bacteria which is spread through inhaling/swallowing airborne droplets
What is Mycobacterium Tuberculosis
The exchange of oxygen and carbon dioxide between the bloodstream and body tissues, and the lungs and the blood stream is due to this process
What is diffusion?
These are the four paranasal sinuses
What are the frontal, maxillary, sphenoidal, and ethmoidal sinuses?
This structure consists of two layers of serous membrane and encloses the lungs
What is the pleura?
Gas exchange occurs here
What are the capillaries of the alveoli?
This type of pneumonia is caused by inhalation of vomit
Aspiration Pneumonia
These muscles of expiration are used when people need more forceful expiration, such as when they are singing, speaking, or doing heavy work
What are internal intercostals and abdominal muscles?
This is the upper section of the pharynx that is located directly behind the nasal cavities
What is the nasopharynx
Inner surfaces of the alveoli are covered with this lipid substance that helps prevent collapsing
What is surfactant?
Oxygenated blood travels throughout the body, while carbon dioxide travels back here to be expelled
What are the lungs?
