Respiratory System Principles of HS
Terms in this set (82)
4-6 minutes of oxygen
How much oxygen do we have?
Openings into which air enters
made of cartilage and divides the nose
2 Hollow spaces lined with a mucous membrane with a
rich blood supply
Warms Air, Filters air, Moistens Air
What do the nasal cavities do?
Traps pathogens (germs) and dirt that enter, Lines respiratory system
tiny hairlike structures in nasal cavity, traps dirt, pushed to the esophagus
structures that provide sense of smell
Drain tears from eyes into the nose, provides additional moisture for the air entering the body
cavities in the skull around nasal area.
What provides resonance for the voice?
throat, behind the nasal cavities, air leaves nose and enters this organ
Nasopharynx, Oropharynx, Laryngopharynx
What are the three sections of the Pharynx?
upper portion behind nasal cavities
Pharyngeal tonsils, Eustachian tube
What does the Nasopharynx contain?
located behind ORAL cavity, receives air and food from the mouth
lymphatic tissue in the Oropharynx
bottom sections of pharynx, branches into the trachea and esophagus
carries air to and from the lungs
carries food to the stomach
composed of Thyroid cartilage, located between the pharynx and trachea
largest section of the Larynx
What are the 2 folds in the Larynx?
opening between vocal cords
Vocal cords vibrate when air enters lung
How voice is created?
Leaf-like piece of cartilage that closes to prevent food and liquids going down the wrong pipe
tube extending from larynx to the center of the chest"windpipe"
series of C-shaped cartilage open on the dorsal surface.
What is the Trachea made of?
each division leads to one of the lungs from the trachea
smallest branches, end in air sacs called alveoli
air sacs, composed of only one layer of squamous epithelial tissue
prevents alveoli from collapsing
What does the alveoli contain to exchange gases?
has 3 lobes
has 2 lobes
Why does the left lung only have two lobes?
2-layered membrane or sac that surrounds each lung
attached to surface of lung
attached to chest wall
space between the two layers
provide lubrication during lung expansion
What does the pleural fluid do?
Cavity that houses the lungs, heart and
major blood vessels
process of breathing
process of breathing in air
process of exhaling, or letting air out
dome-shaped muscle that divides the
thoracic & abdominal cavities
Contraction of diaphragm and intercostal
How does Inhalation work?
Diaphragm and intercostal muscles relax
How does Exhalation work?
organ that controls breathing
process of inspiration and exhalation
Raise in the rate of respiration
Decrease in oxygen
exchange of oxygen and CO2 between lungs and bloodstream
The exchange of O2 and CO2 between the tissue
cells and the bloodstream
The exchange of O2 and nutrients in the cells to
produce energy, water and CO2
bronchospasms narrow opening of bronchioles, mucus production increases
inflammation of bronchi and bronchial tubes
Acute and Chronic
What are the two types of bronchitis?
bronchitis caused by infection
occurs after frequent attacks of Acute bronchitis and long-term exposure to pollutants
Damaged cilia and enlargen\d mucous glands
What is Chronic Bronchitis characterized by?
any chronic lung disease that results in
obstruction of airway, Chronic Obstructive Pulmonary Disease
Emphysema and chronic bronchitis
What two main conditions are also "COPD"?
Non-infectious chronic respiratory condition, Lose elasticity, Carbon dioxide remains trapped in the alveoli
capillaries in nose become congested and bleed, Nosebleed
coughing of blood
grating sounds in the lungs
withdrawal of fluid through a needle
Contagious Viral infection of the upper respiratory
system with sudden onset
Inflammation of the LARYNX and VOCAL CORDS
Leading cause of cancer death in both men and women
Small Cell, Squamous cell, Adenocarcinoma
What are the three common types of Lung Cancer?
Inflammation of the PLEURA (membranes around the
lungs and lining the thoracic cavity)
Inflammation or infection of the lungs, Characterized by a build up of exudate in alveoli, Usually caused by bacteria, viruses, protozoa or
Inflammation of nasal mucous membrane
Inflammation of mucous membrane lining sinuses,Caused by bacteria or virus
Condition in which an individual stops breathing while
What gender is Sleep Apnea more common in?
Obstructive Sleep Apnea
Blockage in an air passage while sleeping
Central sleep apnea
Caused by disorder in the respiratory center of the
continuous positive airway pressure, to keep airway open while sleeping
Caused by bacteria (Mycobacterium tuberculosis)
Upper Respiratory Infection(URI)
the "common cold", inflammation for mucous membrane lining upper respiratory tract, caused by viruses
