The Respiratory system
| Question | Answer |
|---|---|
| the _________________is responsible for exchanging atmospheric gases with those in the body's internal environment. | respiratory system |
| _______________is taken up by the blood to fuel metabolism carried out by all of the body's cells | oxygen |
| carbon dioxide, a metabolic waste, is removed from the cells to keep ________________ from seizing up | metabolism |
| ________________is carried out to ensure that atmospheric air comes in contact with the alveoli of the lungs | ventilation |
| the _____________are the site of gaas diffusion | alveoli |
| diffusion can only take place if the partial pressure of each gas is at the appropriate ratio to diffuse ______________ into the blood from teh lungs and carbon dioxide out of the blood into the lungs | oxygen |
| ____________diseases either affect the flow of air through the airways to the lungs, or they are caused by deterioration of the alveoli. | lung |
| some lung disorders block or degrade the _______________lining, preventing the diffusion of gases. | alveolar |
| certain lifestlye habits ______________the chances of lung diseases. | increase |
| aging mostly affects lung _____________ and contributes to diseases that impair the airways. | elasticity |
| ______________infections and pollution contribute to lung aging. | microbial |
| diseases of the ________________system also affect the respiratory system. | cardiovascular |
| the respiratory system provides cells with the gas exchange needed for _________________ | metabolism |
| breathing, or _________________ brings air into the respiatory system | ventilation |
| gases are exchanged between the respiratory system and the blood by _______________ | diffusion |
| the respiratory system is composed of the nose, __________________, paranasal sinuses, ________________, larynx, ______________, bronchial tree and lungs | nasal cavity, pharynx, trachea |
| ___________is cleaned and moistened in the nose, nasal cavity, paranasal sinuses, and pharynx | air |
| the nose, nasal cavity, paranasal sinuses, and pharynx make up the ______________respiratory system | upper |
| the larynx, trachea, bronchial tree, and lungs make up the _____________respiratory system | lower |
| the _______________regulates coughing and separated the air and food parthways | larynx |
| the _______________and _________________ direct air to the lungs | trachea, bronchial tree |
| ________________regulate the flow of air to lobules in the lungs | bronchioles |
| ______________are pockets of alveoli and blood vessels | lubules |
| diffusion of gases takes place on the walls of the ________________ | alveoli |
| _______________is due to the action of the muscles and bones of the thorax | breathing |
| the ________________ and ________________nervous systems control breathing | autonomic, somatic |
| inspration is due to contraction of the _______________and expansion of the _________ | diaphragm, rib cage |
| ________________is due to relaxation of the diaphragm and external contraction of intercostal muscles | expiration |
| alveoli expand and fill with air upon ______________ | inspiration |
| the _________________of gases in the air determines the direction of diffusion during breathing | partial pressure |
| diseases of the respiratory system are ________________ or ________________ | developmental, infectious |
| _________________diseases are sue to genetic conditions or life style factors | developmental |
| developmental diseases affect the ___________ of the alveoli | airways |
| microorganisms cause ______________ diseases | infectious |
| most __________________cause disease specific to only the upper respiratory system or only the lower respiratory system | microorganisms |
| some aging is due to _________ and __________ on the body | wear, tear |
| _______________plays a significant role in respiratory system aging | lifestyle |
| aging reduces the ability to carry out _______________ and _________________ | inspiration, expiration |
| _________________reduces the diffusion of gases acroos the alveoli | aging |
| aging of the respiratory system can be measured as different aspects of _____________________ | breathing capacity |
| much of the respiratory system is lined with __________________ | mucous membrane |
| the respiratory system develops from the embryonic ______________ system | digestive |
| the shpae of the bronchial tree is supported by _________________ | cartilage rings |
| in the respiratory tree, the _____________ has the smallest diameter | bronchiole |
| in the respiratory system, gas exchange takes place in the ________________ | alveolus |
