| Term | Definition |
|---|---|
| Alveoli | A tiny, thin-walled, capillary-rich sac in the lungs where the exchange of oxygen and carbon dioxide takes place. Also called air sac. |
| 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 |
| Bronchioles | any of the minute branches into which a bronchus divides. |
| Carbaminohemoglobin | Carbaminohemoglobin is 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 | 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. |
| 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 | 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. |
