Question | Answer |
alveoli | made of one layer or squamous epithelial tissue and contain a rich network of blood capillaries. |
bronchi | two main branches of the trachea; air tubes to and from the lungs |
bronchioles | small branches of the bronchi; carry air into the lungs |
cellular respiration | oxygen is carried to the tissue cells by the blood. Since the oxygen concentration is higher in the blood than in the tissue cells, oxygen leaves the blood capillaries and enters the tissue cells. The cells then use the oxygen and nutrients to produce ene |
cilia | tiny, hairlike structures that help the mucous layer that lines the airways oushing trapped particles toward the esophagus where they can be swallowed. |
epiglottis | a special leaflike piece of cartilage, closes the opening into the larynx during swallowing. |
expiration | exhalation. air is forced out of the lungs and into the air passages. |
external respiration | the exchange of oxygen and carbon dioxide between the lungs and bloodstream. |
inspiration | inhalation. the process of breathing in air. |
internal respiration | the exchange of carbon dioxide and oxygen between the tissue cells and the bloodstream. |
larynx | the voicebox that lies between the pharynx and trachea. |
lungs | organs of respiration located in the thoracic cavity. |
nasal cavities | two hollow spaces |
nasal septum | a wall of cartilage dividing the nose into nasal cavities. |
nose | the organ for smelling and breathing |
pharynx | throat |
respiration | the process of taking in oxygen and expelling carbon dioxide from the lungs and air passages |
respiratory system | consists of the lungs and air passages and is responsible for taking in oxygen and removing carbon dioxide. |
Asthma | a respiratory disorder usually caused by a sensitivity to an allergen such as dust, pollen, an animal, or a food. |
Bronchitis | inflammation of the bronchi and bronchial tubes. |
Chronic obstructive pulmonary disease | any chronic lung disease that results in obstruction of the airways. |
Emphysema | a noninfectious, chronic respiratory condition that occurs when the walls of the alveoli deteriorate and lose their elasticity. |
Epistaxis | a nosebleed that occurs when capillaries in the nose become congested and bleed. |
Laryngitis | an inflammation of the larynx and vocal cords. |
Lung Cancer | main cause is exposure to carcinogens in tobacco, either through smoking or through exposure to "second-hand" smoke. |
Pleurisy | an inflammation of the pleura, or membranes, of the lungs |
Pneumonia | an inflammation or infection of the lungs by build up of fluid in the alveoli. |
Rhinitis | an inflammation of the nasal mucous membrane, resuliting in a runny nose, soreness |
