RESPIRATORY SYSTEM Flashcards
the visible structure that forms a prominent feature of the face
EXTERNAL NOSE
the largest part of the external nose is composed of
HYALINE CARTILAGE PLATES
open chamber inside the nose where air first enters the respiratory
system
NASAL CAVITY
external openings of the nasal cavity
NARES / NOSTRILS
the openings into the pharynx
CHOANAE
the anterior portion of the roof of the mouth; it separates the nasal cavity
from the oral cavity
HARD PALATE
the nasal cavity is divided into right and left halves by a partition called
NASAL SEPTUM
three lateral bony ridges / helping
the air churn through the nasal cavity.
CONCHAE
the air passes through tunnels beneath each concha.
MEATUS
within the superior and middle meatuses are openings from the various
PARANASAL SINUSES
common opening of both the digestive and the
respiratory systems.
PHARYNX
three regions of the pharynx
- NASOPHARYNX
- OROPHARYNX
- LARYNGOPHARYNX
it’s is located in the anterior part of the laryngopharynx and extends from the base
of the tongue to the trachea.
LARYNX
largest of the cartilages
THYROID CARTILAGE
an inflammation of the vocal folds
LARYNGITIS
allows air to flow into the lungs
TRACHEA
reinforcing the trachea
15–20 C-SHAPED PIECES OF HYALINE CARTILAGE
consists of the trachea and all other respiratory passageways in the lungs
TRACHEOBRONCHIAL TREE
occurs when the smooth muscle relaxes, making the bronchiole diameter larger.
BRONCHODILATION
occurs when the smooth muscle contracts, making the
bronchiole diameter smaller.
BRONCHOCONSTRICTION
are small, air-filled chambers where the air and the blood come into
close contact with each other.
ALVEOLI
are thin squamous epithelial cells that form 90%
of the alveolar surface.
TYPE I PNEUMOCYTES
are round or cube-shaped secretory cells that
produce surfactant
TYPE II PNEUMOCYTES
is where O2 enters the blood
and CO2 exits the blood.
RESPIRATORY MEMBRANE
separating the two pleural cavities is a central region called ________
MEDIASTINUM
covers the inner thoracic wall.
PARIETAL PLEURA
which covers the surface of the lung
VISCERAL PLEURA
acts as a lubricant, allowing the parietal and visceral pleural membranes
to slide past each other during ventilation.
PLEURAL CAVITY
blood that has passed through the lungs and picked up O2
OXYGENATED BLOOD
the blood that has passed through the tissues and released some of its O2
DEOXYGENATED BLOOD
it is the process of
moving air into and out of the
lungs
VENTILATION
