  19. Respiratory System Key terms • accessory musclesMuscles that help expand small parts of the thoracic cavity, either working in addition to the diaphragm or substituting for it if the diaphragm becomes injured. • acclimatizationLong-term adjustment to high altitude, which is primarily due to increased red blood cell production and capillary tissue perfusion. • ACEAngiotensin converting enzyme, which is secreted in the lungs and helps to increase blood pressure in the body through renal system feedback loops. • acidosisWhen blood pH becomes acidic due to too many hydrogen ions and too much carbon dioxide. • Airway epithelial cellsAirway epithelial cells can secrete a variety of molecules that aid in the immune system defense of lungs. • Airway resistanceAirway Resistance is a concept in respiratory physiology that describes the resistance of the respiratory tract to airflow during inspiration and expiration. • alkalosisWhen blood pH becomes alkaline due to too few hydrogen ions and too little carbon dioxide. • altered breathing patternsAbnormal breathing patterns that indicate typically indicate either too fast or too slow respiratory rate or too much or too little tidal volume. • alveolar dead spaceAlveolar space that can no longer contribute to gas exchange due to damage or scarring. • anaerobic exerciseThis occurs during exercise when the body's oxygen intake doesn't meet oxygen demands to produce enough ATP. • anatomical dead spaceThe space in the respiratory tract that isn't involved in alveolar ventilation and is part of the normal conducting zone of the respiratory system. • ArticulationThe process by which raw phonation from the vocal cords is refined into specific sounds, such as consonants and vowels.

  20. Respiratory System • asthmaA long-term respiratory condition, marked by airway obstruction from bronchospams. It is often in response to an allergen, cold air, exercise, or emotional stress. • atelectasisThe collapse of a part of or the whole lung caused by inner factors, rather than a pneumothorax. • atriumAn upper chamber of the heart that receives blood from the veins and forces it into a ventricle. • BicarbonateA negatively charged ion that accumulates in plasma when carbon dioxide dissolves in water and reacts with it. It also acts as a buffer for blood pH. • bronchoconstrictionThe tightening of the smooth muscle of the bronchi due to parasympathetic nervous system stimulation, excess mucus production, inflammation, or allergic reactions. • bronchopulmonary segmentA distinct functional region of the lung that is separated from the rest of the lung by connective tissue. • bronchusEither of the two airways that are the primary branches of the trachea, leading directly into the lungs. • carbonic anhydraseAn enzyme that catalyzes the bicarbonate reaction in either direction. • cardiac notchA concave impression molded into the left lung to accommodate the shape of the heart. • Cellular respirationThe cellular process of producing adenosine triphosphate (ATP), water, and carbon dioxide from glucose and oxygen. • central chemoreceptorsLocated within the medulla, they are sensitive to the pH of their environment. • chemoreceptersThese are receptors in the medulla and in the aortic and carotid bodies of the blood vessels that detect changes in blood pH and signal the medulla to correct those changes.

  21. Respiratory System • ciliaTiny, hair-like projections from a cell. • cough reflexThis occurs when the larynx closes as it forces air out of the lungs to protect the lungs from aspirated materials. • Dalton's lawThe total pressure of a mixture of gases is the sum of the partial pressures of each gas in the mixture; it is only true for ideal gases. • Dead spaceAny space in the airways that is not involved in alveolar gas exhange, such as the conducting zones. • dissociation curveThe oxygen–hemoglobin dissociation curve plots the proportion of hemoglobin saturated with oxygen on the vertical axis against the partial pressure of oxygen on the horizontal axis. • elastic recoilThe lungs' rebound from the stretch of inhalation that passively removes air from the lungs during exhalation. • EquilibriumThe rate of change of the gasses in the alveoli and capillary become equal to eachother at the end of gas exchange. • exhalationThe act or process of exhaling, or sending forth in the form of steam or vapor; evaporation. • extracellular matrixA fluid space secreted by cells (including alveolar cells) for structural and functional support. • FEV1/FVC ratioThe ratio between forced expiratory volume and forced vital capacity, which is used to measure the level of obstruction in the lungs. • glottisAn organ of speech located in the larynx and consisting of the true vocal cords and the opening between them. • hematocritThis is the amount of red blood cells in a given volume of blood.

  22. Respiratory System • hemoglobinA protein found in red blood cells that provides a binding site for oxygen to transport it to the tissues of the body. • Henry's lawAt a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. • hiliumThe root of the lung that contains the pulmonary veins andarteries that supply blood to the lungs. • hypoxiaA system-wide deficiency in the levels of oxygen that reach the tissues. • inspirationThe drawing of air into the lungs, accomplished in mammals by elevation of the chest walls and flattening of the diaphragm. • Intercostal musclesIntercostal muscles are several groups of muscles that run between the ribs, and help form and move the chest wall. • intrapleural pressureThe pressure inside the pleural cavity, which is negative compared to outside air and becomes even more negative during inspiration. • laryngesPart of the respiratory tract between the pharynx and the trachea, having walls of cartilage and muscle and containing the vocal cords enveloped in folds of mucous membrane. • laryngopharynxThe lower part of the pharynx above the larynx and below the oropharynx. • Lung complianceThe ability of the lungs and pleural cavity to change in volume based on changes in pressure. • mucocilliary escalatorThe ladder formed by mucus and cilia in the trachea that pushes mucus up the trachea and into the pharynx to prevent mucus pathogens from entering the lungs. • nasopharynxThe upper part of the pharynx that connects the nasal cavity to the throat.

  23. Respiratory System • nostrilEither of the two orifices located on the nose (or on the beak of a bird); used as a passage for air and other gases to travel the nasal passages. • oropharynxThe middle part of the pharynx that connects to the oral cavity and the other two chambers of the pharynx. • Oxidative PhosphorylationThe final step of cellular phosphorylation in which oxygen is used to a create an electron transport chain that produces a large amount of ATP from nicotinamide adenine dinucleotide (NADH). • paranasal sinusesFour air-filled spaces around the nasal cavity that perform many functions, such as draining mucus from the nose. • partial pressureThe pressure exerted by a gas, either in air or dissolved, that indicates the concentration of that gas. • partial pressure gradientThe difference between the partial pressures (and thus concentration) of gasses between gaseous and dissolved forms. • passive diffusionNet movement of material from an area of high concentration to an area of lower concentration without any energy input. • passive diffusionThe net movement of material from an area of high concentration to an area of lower concentration without any energy input. • perfusionThe blood supply to the alveolar capillaries that must be balanced with ventilation. • peripheral chemoreceptorsThe aoritic and carotid bodies, which act principally to detect variation of the oxygen concentration in the arterial blood, also monitor arterial carbon dioxide and pH. • plethysmographyThe diagnostic use of a plethysmograph to measure changes in volume within an organ or whole body. • pleuraThe double-layered membranous lining of the thoracic cavity that covers the lungs.

It is often located in areas where the airways branch or diverge. • V/Q ratioThe ratio of ventilation and blood perfusion of the lungs. Its balance is an important indicator of lung function and efficiency. • ventilationThe bodily process of breathing, the inhalation of air to provide oxygen, and the exhalation of spent air to remove carbon dioxide. • ventilationThe bodily process of breathing, the inhalation of air to provide oxygen, and the exhalation of spent air to remove carbon dioxide. • ventricleThe lower chamber of the heart that receives blood from the atrium and pumps it into the arteries. • vital capacityThe maximum volume of air that can be discharged from the lungs following maximum inspiration. • vocal cordsTwo folds of tissue located in the larynx that vibrate when air passes over them, producing the sound waves associated with talking and singing.
