Flashcards in Respiratory System Deck (104):
The exchange of gases (oxygen and CO2) at the lung capillaries (external respiration) and at the tissue capillaries (internal respiration). The mechanical process of breathing.
Opening through the nose carrying air into the nasal cavity
Thin hairs that line the nasal cavity passageways and tubes of the respiratory tract to filter out foreign bodies and warm and moisten the air
Hollow, air-containing spaces within the skull that communicate with the nasal cavity. They have a mucous membrane lining and produce mucus, lighten the bones of the skull, and help produce sound
What are the three divisions of the pharynx?
What are found in the nasopharynx?
Pharyngeal tonsils (adenoids)
The exchange of air between the lungs and the outside environment
What are adenoids?
Small masses of lymphatic tissue in the throat (nasopharynx); aka pharyngeal tonsils
Two rounded masses of lymphatic tissue in the oropharynx
Referring to the roof of the mouth
Exchange of gasses between individual body cells and the capillaries that surround them
Serves as a common passageway for food from the mouth and air from the nose. Has two divisions
What are the two divisions of the laryngopharynx
Larynx and the esophagus
What is the larynx?
Tube that leads to the stomach and carries food to be digested
A flap of cartilage attached to the root of the tongue that covers the larynx and prevents choking or aspiration of food by blocking entry to the larynx and trachea during swallowing
Windpipe; tube leading from the larynx (voice box) to the bronchial tubes
Region between the lungs in the chest cavity. it contains the trachea, heart, lymph nodes, aorta, esophagus, and bronchial tubes
Branch of the trachea that is a passageway into the lung
smallest brnches of the bronchi
Air sac in the lung
Cells in the blood that carry oxygen away from the lungs to all parts of the body and carbon dioxide back to the lungs for exhalation
Double-layered membrane surrounding each lung
What are the two layers of the Pleura?
1. Parietal Pleura
2. Visceral Pleura
What are the differences btw the lungs?
The right lung is slightly larger and has three lobes while the left has two
Uppermost part of the lung
Lower portion of the lung
The midline region of the lung in which blood vessels, nerves, lymphatic tissue, and bronchial tubes enter and exit
Muscular partition separating the thoracic from the abdominal cavity. Contracts to pull air in the lungs and relaxes to push air out
Pathway of air from the nose to the capillaries of the lungs
Nose (nares) - Nasal cavity and paranasal sinuses - Pharynx - Larynx - Trachea - Bronchi - Bronchioles - Alveoli - Lung Cappilaries
Gas produced by the body when oxygen and carbon atoms from food combine
Slit-like opening to the larynx
Gas that makes up 21% of the air
Space between the folds of the pleura
Alveolus, air sac
Bronchial tube, Bronchus
Larynx, voice box
Lobe of the lung
pleural cavity, chest
Involuntary muscular contractions in bronchial tubes leading to narrowing of the bronchi
Increased levels of carbon dioxide in the bloodstream
Abnormal condition of bluish coloration of the skin
Involuntary contraction of muscles
Placement of a tube through the nose into the stomach
Abnormal condition in which breathing is easier in the upright position
Coughing up of mucus or sputum from the throat and respiratory tract
bad painful, difficult, abnormal
the escape of fluid from blood vessels or lymphatics into a cavity or into tissue spaces
Collection of air or gas in the pleural cavity between the pleura and surrounding the lungs
surgical repair of he nose
Discharge of mucus from the nose. "Runny nose"
tool to measure breathing
Loss of sense of smell
difficult breathing (SOB-shortness of breath)
increase in breathing rate, occurring normally with exercise and abnormally with an condition in which the oxygen supply is inadequate
excessively rapid and shallow breathing; hyperventilation
Spitting up blood
Deficient oxygen and increased carbon dioxide in the bloodstream
Asphyxia - "lack of pulse"
Blood in the chest (pleural cavity) surrounding the lungs
Pus collection in the pleural cavity
Listening to sounds within the body with a stethoscope
Tapping on the surface to determine the underlying structure
Scratchy sound produced by inflamed or irritated pleural surfaces rubbing against each other.
Fine crackling sounds heard on auscultation (during inhalation) when there is fluid in the alveoli
Loud rumbling sound heard on auscultation of bronchi obstructed by sputum
Rhonchi (sing- Rhonchus)
Materiel expelled from the bronchi, lungs, or upper respiratory tract by spitting
Strained, high pitched sound heard on inspiration caused by obstruction in the pharynx or larynx
