the upper respiratory system
bronchial tree and lungs located and protected within the thoracic cavity
the lower respiratory system
ribcage
thorax
a wall of cartilage that divides the nose into two equal sections
nasal septum
the thin hairs located just inside the nostrils, filter incoming air to remove debris.
Cilia
Specialized tissues line the nose also line the digestive, reproductive, and urinary systems as well as other parts of the respiratory system.
Mucous membranes
a slippery secretion produced by the mucous membranes that protects and lubricates these tissues
mucus
nerve endings that act as the receptors for the sense of smell
olfactory receptors
part of the lymphatic system (CH.6) protect from infection coming in from nose or mouth. A.K.A. palatine tonsils(back of mouth) and nasopharyngeal tonsils (behind nose and roof of mouth)
tonsils and adenoids
air-filled cavities lined with mucous membrane, are located in the bones of the skull
paranasal sinuses
(near/nasal/pertaining to)
___located in the frontal bone just above eyebrows; ___located in the sphenoid bone behind the eye and under the pituitary gland, are close to optic nerve, and an infection here can damage vision; ___the largest of the paranasal sinuses, are located in the maxillary bones under the eyes; ___located in the ethmoid bones between the nose and the eyes, are irregularly shaped air cells that are separated from the orbital (eye) cavity only by a thin layer of bone.
frontal sinuses, sphenoid sinuses, maxillary sinuses, and ethmoid sinuses
commonly known as the throat, receives the air after it passes through the nose or mouth, as well as food
pharynx
posterior to nasal cavity and continues downward behind the mouth. (three divisions)
nasopharynx
(nose/throat)
the portion that is visible when looking into the mouth (three divisions)
oropharynx
(mouth/throat)
or/o
mouth
;where food and air cross paths. also shared by both the respiratory and digestive systems (air, food, fluids, continue down to openings of the esophagus and trachea)
laryngopharynx
(larynx/throat)
the voice box, a triangular chamber located between the pharynx and the trachea. contains the vocal cords and is supported by a series of separate cartilages. The thyroid cartilage is the largest and when enlarged projects from the front of the throat a.k.a the Adam’s apple.
larynx
a lid-like structure located at the base of the tongue, swings downward and closes off the laryngopharynx so that food does not enter the trachea and the lungs
epiglottis
role is to transport air to and from the lungs. A.K.A the windpipe, located directly in front of the esophagus.
trachea
two large tubes, brunch out from the trachea and convey air into the two lungs
bronchi
within the lung, each primary bronchus divides and subdivides into increasingly smaller_____, the smallest branches of the bronchi.
bronchioles
a.k.a. air sacs, are very small, grapelike clusters found at the end of each bronchiole. (Produces a detergent-like substance, known as surfactant, to reduce the surface tension of the fluid in the lungs.
alveoli
relating to or affecting the lungs
pulmonary
the essential organs of respiration, are divided into lobes
lungs
larger and has three lobes: the upper, middle, and lower (superior, middle, and inferior)
right lung
has only two lobes, the upper and lower, due to space restrictions because the heart is located on that side of the body
left lung
the middle section of the chest cavity and is located between the lungs.
mediastinum
a thin, moist, and slippery membrane that covers the outer surface of the lungs and lines the inner surface of the thoracic cavity
pleura
the outer layer of the pleura. It lines the walls of the thoracic cavity, cover the diaphragm, and forms the sac containing each lung.
parietal pleura
(parietal means relating to the walls of a cavity)
the inner layer of pleura that covers each lung, is attached directly to the lungs.
visceral pleura
(visceral means relating to the internal organs)
a.k.a_ space, the thin, fluid-filled space between the parietal and visceral pleural membranes.
pleural cavity
a dome-shaped sheet of muscle that separates the thoracic cavity from the abdomen
diaphragm
what thing stimulates the diaphragm and cause it to contract
phrenic nerves
breathing, is the exchange of oxygen for carbon dioxide that is essential to life
respiration
the act of taking in air as the diaphragm contracts and pulls downward
inhalation
the act of breathing out. As the diaphragm relaxes, it moves upward, causing the thoracic cavity to become narrower.
exhalation
the act of bringing air in and out of the lungs from outside environment and, in the process, exchanging oxygen for carbon dioxide
external respiation
the exchange of gases within the cells of the blood and tissues
internal respiration (a.k.a. cellular respiration)
a.k.a. ENT, a physician with specialized training in the diagnosis and treatment of diseases and disorders of the head and neck
otolaryngologist
(ear/larynx/specialist)
a physician who specializes in diagnosing and treating diseases and disorders of the respiratory system
pulmonologist (lung/specialist)
a licensed medical professional who specializes in treating patients who are having difficulty breathing, both in hospital and outpatients settings.
respiratory therapist (RT)
performs operations on the organs inside the thorax, or chest, including the heart, lungs, and esophagus.
thoracic surgeon
a group of lung diseases in which the bronchial airflow is obstructed, making it difficult to breathe out.
Chronic obstructive pulmonary disease (COPD)
a disease in which the airways have become inflamed due to recurrent exposure to an inhaled irritant, usually cigarette smoke.
chronic bronchitis
(bronchus/inflammation)
the progressive, long-term loss of lung function, usually due to smoking.
Emphysema
a chronic inflammatory disease of the bronchial tubes, often triggered by an allergic reaction.
asthma
___characterized by episodes of severe breathing difficulty, coughing, and wheezing. (a breath sound caused by partially obstructed airway.)
asthma attack
the swelling and clogging of the bronchial tubes with mucus.
airway inflammation
a contraction of the smooth muscle in the walls of the bronchi and bronchioles, tightening and squeezing the airway shut
bronchospasm
(bronchi/involuntary contraction)
this and acute nasopharyngitis both describe the common cold.
upper respiratory infections (URI)
commonly referred to as an allergy, is an allergic reaction to airborne allergens that causes an increased flow of mucus.
allergic rhinitis
(nose/inflammation)
an acute respiratory infection in children and infants characterized by obstruction of the larynx, hoarseness, and swelling around the vocal cords resulting in a barking cough and stridor.
Croup
a.k.a. nosebleed, is bleeding from the nose that may be caused by dry air, injury, medication to prevent blood clotting, or high blood pressure.
Epistaxis
an acute, highly contagious viral infection characterized by respiratory inflammation, fever, chills, and muscle pain.
