| antegrade pyelography | Antegrade urography in which the contrast medium is injected into the renal calices or pelvis. (05 Mar 2000) |
|---|---|
| retrograde pyelography | Pyelography in which contrast material is injected into the ureters from an endoscope in the bladder. (05 Mar 2000) |
| pyelography | <investigation, radiology> Radiologic study of the kidney, ureters, and usually the bladder, performed with the aid of a contrast agent either injected intravenously, or directly through a ureteral or nephrostomy catheter or percutaneously. Synonym: pelviureterography, pyeloureterography, ureteropyelography. Origin: pyelo-+ G. Grapho, to write (05 Mar 2000) |
| intravenous pyelography | Former name for intravenous urography. (05 Mar 2000) |
| abdominal respiration | Breathing effected mainly by the action of the diaphragm. (05 Mar 2000) |
| aerobic respiration | A form of respiration in which molecular oxygen is consumed and carbon dioxide and water are produced. (05 Mar 2000) |
| amphoric respiration | A sound like that made by blowing across the mouth of a bottle, heard on auscultation in some cases in which a large pulmonary cavity exists, or occasionally in pneumothorax. (05 Mar 2000) |
| anaerobic respiration | Respiration under anaerobic conditions. The terminal electron acceptor, instead of oxygen in the case of regular respiration, can be: carbon dioxide, Fe2+, fumarate, nitrate, nitrite, nitrous oxide, sulphur, sulphate, etc. Note that anaerobic respiration still uses the electron transport chain to dump the electron while fermentation does not.

| artificial respiration | Application of mechanically or manually generated pressures, usually positive, to gas(es) in or about the airway as a means of producing gas exchange between the lungs and surrounding atmosphere. Synonym: artificial respiration. (05 Mar 2000) |
| assisted respiration | Application of mechanically or manually generated positive pressure to gas(es) in or about the airway during inhalation as a means of augmenting movement of gases into the lungs. Synonym: assisted respiration. (05 Mar 2000) |
| Biot's respiration | Completely irregular breathing pattern, with continually variable rate and depth of breathing; results from lesions in the respiratory centres in the brainstem, extending from the dorsomedial medulla caudally to the obex. Synonym: ataxic breathing, Biot's breathing, respiratory ataxia. (05 Mar 2000) |
| bronchial respiration | A tubular blowing sound caused by the passage of air through a bronchus in an area of consolidated lung tissue. (05 Mar 2000) |
| bronchovesicular respiration | Combined bronchial and vesicular respiration. (05 Mar 2000) |
| paradoxical respiration | Deflation of the lung during inspiration and inflation of the lung during the phase of expiration; seen in the lung on the side of an open pneumothorax. (05 Mar 2000) |
| vesicular respiration | The respiratory murmur heard on auscultating over the normal lung. Synonym: respiratory murmur, vesicular murmur. (05 Mar 2000) |
