| Term | Definition |
|---|---|
| tournaquet | constricting band applied to a limb to control bleeding or to assist in drawing blood |
| myocardium | middle/thickest layer of the heart |
| epicardium | external layer of heart; aka visceral layer of pericardium |
| crescendo murmur | abnormal swooshing cardiac sounds that progressively increase in loudness |
| arterioles | smaller branches of arteries |
| apex | narrow tip of the heart |
| celiac artery | supplies liver, stomach, and spleen; coallia=belly |
| sephalic vein | runs down front leg/arms; injections/IV |
| heart murmur | abnormal sound associated with turbulent flow of blood |
| aneurysm | localized balloon like enlargement of an artery |
| sinoatrial node (SA Node) | located in wall of right atrium near entrance of superior vena cava |
| lumen | opening in a vessel through which fluid flows |
| stethescope | instrument used to listen |
| auscult | listen |
| transfusion | introduction of whole blood/blood components into the blood stream of the recipient |
| systole | generally, means contraction; drawn together heart squeezes-is active |
| diastole | heart opens/relaxed |
| left atrio-ventricular valve | valve controls opening between left atrium and left ventricle |
| electrocardiography (ECG) | process of recording the electrical activity of the myocardium |
| aorta | biggest vessel leaving the heart to the kidneys; thick walls |
| pulse | |
| blood pressure | tension exerted by blood on the arterial walls |
| capillaries | single-cell thick vessels that connect the arterial/venous systems |
| hypertension | high blood pressure |
| cardiac catheterization | radiographic study in which a catheter is passed into a blood vessel and guided into the heart to detect pressures/patterns of blood flow |
| defibrillation | use of electrical shock to restore the normal heart rhythm |
| sinus rhythm | normal rhythm because it starts in sinoatrial node |
| ovarian arteries | supply ovaries/testicles |
| pharynx | air passes through nasal cavity; commonly called throat, common passageway for upper respiratory/gastrointestinal tracts |
| apnea | absence of breathing |
| sinuses | air filled/fluid filled space |
| frontal | dorsal part of skull between nasal cavity and orbit |
| nasogastric tube (NG tube) | tube passing through nose down to stomach |
| parenchyma | functional elements of an organ |
| phlegm | thick mucus secreted by the respiratory lining |
| thorax | chest cavity/chest |
| bronchial | combining forms from bronchiola |
| parietal pleura | outer layer of membrane lining the inner wall of the thoracic cavity |
| visceral pleura | inner layer of the membrane lining the outside of the lung |
| dead space | air in pathway of the respiratory system (dead bc air isn't currently participatin gin gas exhange) |
| hyperventilation | abnormally rapid deep breathing, resulting in decreased levels of cellular carbon dioxide |
| hypopnea | abnormally slow/shallow respirations |
| hyperpnia | abnormal increase in respirations |
| receptors | responsible for sense of smell |
| tracheitis | inflammation of the trachea |
| bronchitis | inflammation of the bronchi |
| tracheal wash | collection of fluid/mucus from the trachea via and endotracheal tube to assess respiratory disease. fluid may be used for cytologic/microbiologic examination |
| pleurisy/pleuritis | inflammation of the pleura; aka pleuritis |
| pharyngotomy | surgical incision of the throat |
| bronchoalveolar lavage | collection of fluid/mucus from bronchi/alveoli via endoscope/through and endotracheal tube inserted as far down trachea caudally as possible before infusing fluid/aspirating a sample. fluid may be used for cytologic examination. |
| hemoptosis | spitting of blood from the lower respirotory tract |
| diaphragmatic hernia | abnormal displacement of organs through the muscle separating the chest/abdomen |
| chest tube | |
| spirometer | instrument used to take air in and out of the lungs |
| hemothorax | accumulation of blood in the chest cavity |
| hemoperitoneum | accumulation of blood in the abdominal cavity |
| hypoxia | inadequate supply of oxygen to tissue despite and adequate oxygen supply |
| metabolic acidosis/alkalosis | changes in blood pH can result from metabolic factors |
| tonsils | lymphatic tissue that protects the nasal cavity and proximal(upper) throat |
| windpipe | extends from neck to chest |
| respiratory rate | number of respirations per minute |
