Respiratory Flashcards
It is the movement of air into and out of the lungs.
Ventilation
parts of the process of respiration
movement of air into and out of the lungs; exchange of oxygen and carbon dioxide between the air in the lungs and the blood; transport of oxygen and carbon dioxide in the blood
upper respiratory tract
larynx; Oropharynx; Nasal cavity
lower respiratory tract
trachea; Alveoli ; Bronchioles
Most of the structures of the external nose is composed of what type of cartilage?
Hyaline
The opening to the pharynx found in the nasal cavity is called
Choanae
These are bony ridges on the lateral walls on each side of the nasal cavity
Nasal conchae
The largest paranasal sinus is the
Maxillary sinus
Sneeze reflex, which cranial nerve?
Trigeminal nerve
Which part of the respiratory tract serves as the common passageway for both air and food?
Pharynx
During swallowing, which structure elevates to close the nasopharynx and prevent entry of food into the nose?
Soft palate & uvula
This structure is found on the posterior part of the nasopharynx which is described as an extension of the soft palate?
Uvula
The largest cartilage in the larynx is the
Thyroid cartilage
The most inferior among the unpaired cartilages in the larynx is the
Cricoid cartilage
This structure protects the airway by covering the glottis during the process of swallowing
Epiglottis
The epiglottis is made up of what type of cartilage?
Elastic
trachea
It is composed of 16-20 C-shaped pieces of hyaline cartilage.
This is an involuntary response which results to the contraction of the smooth muscle in the trachea that can narrow its diameter to expel mucus
Cough reflex
The left lung has how many lobes?
2
anatomy of the primary bronchi?
The right bronchus is wider, shorter and more vertical.
The principal organ of respiration
Lungs
This is the lipoprotein molecule secreted by cells within the walls of the alveoli that reduces the surface tension in the alveoli
Surfactant
This Is the serous membrane that lines the walls of the thorax, diaphragm and mediastinum
Parietal pleura
This term refers to the movement of air out of the lungs
Expiration
