the respiratory system study guide

consists of the lungs and air passages, responsible for taking in oxygen and removing carbon dioxide respiratory system
has two openings, the nostrils/nares through which air enters. nose
a wall of cartilage that divides the nose into two hollow spaces nasal septum
cavities that are lined with a mucous membrane and have a rich blood supply nasal cavities
tiny, hairlike structures which filter inhaled air to trap dust and other particles cilia
drain tears from the eye into the nose to provide additional moisture for the air nasolacrimal ducts
cavities in the skull that surround the nasal area, provide resonance for the voice sinuses
also known as the throat lies directly behind the nasal cavities, divided into 3 sections pharynx
also known as the voice box, lies between the pharynx and trachea, it has 9 layers of cartilage larynx
a special leaflike piece of cartilage which closes the opening into the larynx during swallowing to prevent food and liquid from entering the respiratory tract epiglottis
also known as the windpipe, a tube extending from the larynx to the center of the chest, a series of c shaped cartilages(which are open on the dorsal, or back, surfaces) help keep the trachea open trachea
the trachea divides into 2 of these near the center of the chest, each one enters a lung and carries air from the trachea to the lung bronchi
smallest branches of the bronchi within the lung bronchioles
resembles a bunch of grapes, the adult lung contains approximately 500 million of these, they contain a rich network of blood capillaries which allow oxygen and carbon dioxide to be exchanged between the blood and lungs. alveoli
the part of the respiratory system responsible for taking in oxygen and removing carbon dioxide, located in the thoracic cavity lungs
a membrane or sac in which each lung is enclosed, it consists of two layers of serous membrane pleura
the process of breathing, it involves two phases; inspiration and expiration ventilation
the process of breathing in air inspiration
this process is when air is forced out of the lungs and air passages by relaxation of the diaphragm and intercostal muscles expiration
the process of inspiration and expiration respiration
one of the two main stages of respiration, it is the exchange of oxygen and carbon dioxide between the lungs and bloodstream external respiration
the exchange of carbon dioxide and oxygen between the tissue cells and the blood stream internal respiration
this process occurs when tissue cells use the oxygen and nutrients it received from the blood to produce energy, water, and carbon dioxide cellular respiration
a respiratory disorder in which bronchospasms narrow the openings of the bronchioles, mucus production increases, and edema develops in the mucosal lining asthma
an inflammation of the bronchi and bronchial tubes bronchitis
a nosebleedd that occurs when capillaries in the nose become congested and bleed epistaxis
any chronic lung disease that results in obstruction of the airways chronic obstructive pulmonary disorder
an inflammatin or infection of the lungs characterized by exudate (a buildup of fluid) in the alveoli pneumonia
an inflammation of the mucous membrane lining the sinuses sinusitis
an inflammation of the larynx and vocal cords laryngitis
an inflammation of the pleura, or membranes, of the lungs pleurisy
an inflammation of the nasal mucous membrane, resulting in a runny nose, watery eyes, sneezing, soreness, and congestion rhinitis
a preventable disease, it is the leading cause of cancer death in both men and women lung cancer
a condition in which an individual stops breathing while asleep, causing a measurable decrease in blood oxygen levels sleep apnea
a noninfectious, chronic respiratory condition that occurs when the walls of the alveoli deteriorate and lose elasticity emphysema
also known as the flu, is a highly contagious VIRAL infection of the upper respiratory system influenza
an infectious lung disease caused by the bacterium Mycobacterium tuberculosis TB (tuberculosis)
the body has a _____ to _____ minute supply of oxygen 4 to 6 minute
the largest layer of cartilage on the larynx, the thyroid cartilage, is commonly called ___________ the adams apple
a series of c shaped cartilages, open to the _______ or ________ surface, help keep the trachea open dorsal , back
the left lung has ______ lobesthe right lung has ______lobes 2 lobes3 lobes
during expiration the diaphragm and the intercostal muscles ________ relax
the process of respiration is controlled by the respiratory center in the _________ of the brain medulla oblongata
an increased amount of carbon dioxide causes an ___________- in respiratory rate increase
to stop a nosebleed compress the nostrils and tilt the head _________ slightly forward
the __________ pleura is attached to the surface of the lung visceral
influenza is also known as the _________ flu
most upper respiratory infections are caused by ___________ and are highly contagious viral infections
withdrawal of fluid through a needle thoracentesis
a respiratory disorder caused by a sensitivity to an allergen is asthma
a CPAP is mainly used for the disorder known as sleep apnea
a treatment for COPD is bronchodilators, mucolytics, cough medications
a decreased amount of _____ in the blood causes the respiratory center in the medulla oblongata to increase the rate of respirations oxygen
the esophgus and trachea branch off of the laryngopharynx
why is the left lung smaller than the right lung due to the heart lying more to the left side of the chest
