| Term | Definition |
|---|---|
| alveoli | a small cavity, pit, or hollow, in particular. |
| aortic bodies | The aortic body is one of several small clusters of chemoreceptors, baroreceptors, and supporting cells located along the aortic arch. |
| bronchi | Two main branches of the trachea that go into the lungs. This then further divides into the bronchioles |
| bronchioles | any of the minute branches into which a bronchus divides. |
| carbaminohemoglobin | a compound of haemoglobin and carbon dioxide, and is one of the forms in which carbon dioxide exists in the blood. 10% of carbon dioxide is carried in blood this way |
| carbonic anhydrase | an enzyme that catalyzes the interconversion of dissolved bicarbonates and carbon dioxide. |
| carotid bodies | a small mass of receptors in the carotid artery sensitive to chemical change in the blood. |
| diaphragm | a dome-shaped, muscular partition separating the thorax from the abdomen in mammals. It plays a major role in breathing, as its contraction increases the volume of the thorax and so inflates the lungs |
| exhalation | the process or action of exhaling |
| external respiration | breathing: the bodily process of inhalation and exhalation; the process of taking in oxygen from inhaled air and releasing carbon dioxide by exhalation |
| inhalation | the action of inhaling or breathing in |
| internal respiration | the metabolic processes whereby certain organisms obtain energy from organic molecules; |
| larynx | the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box. |
| oxyhemoglobin | a bright red substance formed by the combination of hemoglobin with oxygen, present in oxygenated blood. |
| pharynx | the membrane-lined cavity behind the nose and mouth, connecting them to the esophagus. |
| pleural membrane | the pleural cavity is the potential space between the two pleurae of the lungs. The pleura is a serous membrane which folds back onto itself to form a two-layered membrane structure. |
| reduced hemoglobin | A combination of hemoglobin and carbon dioxide that is found in venous blood. |
| medulla oblongata | the continuation of the spinal cord within the skull, forming the lowest part of the brainstem and containing control centers for the heart and lungs. |
| stretch receptors | a sensory receptor that responds to the stretching of surrounding muscle tissue and so contributes to the coordination of muscle activity. |
| thoracic cavity | chest cavity: the cavity in the vertebrate body enclosed by the ribs between the diaphragm and the neck and containing the lungs and heart |
| trachea | a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe. |
