| 영문 | osmotic pressure | 한글 | 삼투압 |
|---|---|---|---|
| 설명 | 삼투라는 현상은 일정 크기 이하의 물질은 통과시키고 그 이상의 크기를 가진 물질은 통과 시키지 못하게 하는 막(반투막)을 사이에 두고 양쪽에 그 막을 투과하지 못하는 물질의 농도가 차이가 날 때 발생하는 것으로 막을 통과할 수 있는 물질이 막 양쪽의 통과 할 수 없는 물질의 농도를 같게 하는 방향으로 움직이는 것을 말한다. |

| 영문 | systolic pressure | 한글 | 수축기압 |
|---|---|---|---|
| 설명 | 심활동력, 동맥벽의 탄력성, 혈액량, 혈액의 점성 등에 의하여 결정되는 혈액의 동맥벽에 미치는 압력으로서, 최고혈압은 왼심실로부터 박출이 끝나기 직전에 생기는 압을 말하고 최대 혈압 또는 수축기혈압이라 부른다. 최소혈압은 왼심실의 확장이 끝나는 시기에 생기는 혈압을 말하며 최소혈압 또는 확장기혈압이라고 부른다. 평균혈압은 동맥내압의 평균치를 말하며, 기초혈압은 절대안정 상태에서 측정한 혈압을 말한다. |

| 영문 | blood pressure | 한글 | 혈압 |
|---|---|---|---|
| 설명 | 혈압이란 혈관에 걸리는 압력을 말하는 것으로 대개 특별한 설명이 없으면 동맥의 압력을 말한다. 혈압에는 수축기혈압(systolic blood pressure)과 이완기혈압(diastolic blood pressure)이 있다. 수축기혈압이란 심장이 수축할 경우에 동맥에 걸리는 압력을 말하고, 이완기 혈압이란 심장이 이완할 경우에 동맥에 걸리는 압력을 말한다. 당연히 수축기 혈압이 이완기 혈압보다 높다. 혈압을 말할 때에 예를 들어 120/80mmHg이라고 적는 것의 앞의 것은 수축기 혈압을 의미하고 뒤에 적는 80은 이완기 혈압을 의미한다. |

| wedge-tailed | <ornithology, zoology> Having a tail which has the middle pair of feathers longest, the rest successively and decidedly shorter, and all more or less attenuate; said of certain birds. Wedge-tailed eagle, an Australian eagle (Aquila audax) which feeds on various small species of kangaroos, and on lambs; called also mountain eagle, bold eagle, and eagle hawk. Wedge-tailed gull, an arctic gull (Rhodostethia rosea) in which the plumage is tinged with rose; called also Ross's gull. Source: Websters Dictionary (01 Mar 1998) |

| quartz wedge | <microscopy> A compensator consisting of a gradual wedge of quartz of such orientation and dimensions as to show at least several orders of retardation colours as illustrated by the Michel Levy scale of retardation colours and birefringence vs. Thickness of specimen. The Babinet compensator employs two opposing quartz wedges, calibrated in terms of retardation. (05 Aug 1998) |
| ovarian wedge resection | <gynaecology, procedure> The surgical removal of a portion of a polycystic ovary to induce ovulation. (05 Jan 1998) |
| abdominal pressure | Pressure surrounding the bladder; estimated from rectal, gastric, or intraperitoneal pressure. (05 Mar 2000) |
| absolute pressure | Pressure measured with respect to zero pressure. Compare: gauge pressure. (05 Mar 2000) |
| acoustic pressure | In ultrasound, the instantaneous value of the total pressure minus the ambient pressure; unit is pascal (Pa). (05 Mar 2000) |
| air pressure | The force per unit area that the air exerts on any surface in contact with it. Primarily used for articles pertaining to air pressure within a closed environment. (12 Dec 1998) |
| atmospheric pressure | The pressure at any point in an atmosphere due solely to the weight of the atmospheric gases above the point concerned. (12 Dec 1998) |
| back pressure | Pressure exerted upstream in the circulation as a result of obstruction to forward flow, as when congestion in the pulmonary circulation results from stenosis of the mitral valve or failure of the left ventricle. (05 Mar 2000) |
| back-pressure renal atrophy | <radiology> Caliectasis without obstruction, due to repeated episodes of obstruction, gradual loss of renal pyramids (12 Dec 1998) |
| barometric pressure | The absolute pressure of the ambient atmosphere, varying with weather, altitude, etc.; expressed in millibars (meteorology) or mm Hg or torr (respiratory physiology); at sea level, one atmosphere (atm, 760 mm Hg or torr) is equivalent to: 14.69595 lb/sq in, 1013.25 millibars, 1013.25 × 106 dynes/cm2, and, in SI units, 101,325 pascals (Pa). Synonym: atmospheric pressure. (05 Mar 2000) |
| bile duct pressure | <radiology> Normal: 15-20 cm H2O (12 Dec 1998) |
| biting pressure | Any force exerted upon the occlusal surfaces of teeth. Synonym: biting pressure. (05 Mar 2000) |
| blood pressure | <cardiology, physiology> The force that the circulating blood exerts on the walls of the arteries. This measurement is divided into systolic (pressure during contraction of the heart) and diastolic (pressure during relaxation phase). Blood pressure varies with age and sex of the individual. A rough rule of thumb for normal systolic pressure is 100 + Age of individual. In children 2 x (age) + 80 = systolic BP The diastolic pressure should be roughly 2/3 the systolic pressure.
