| 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. |

| arterial blood gas | A test which analyses arterial blood for oxygen, carbon dioxide and bicarbonate content in addition to blood pH. Used to test the effectiveness of respiration. Acronym: ABG (17 Oct 1997) |

| arterial bulb | The dilated first part of the aorta containing the aortic semilunar valves and the aortic sinuses. Synonym: bulbus aortae, arterial bulb. (05 Mar 2000) |
| arterial canal | Before birth, the blood headed from the heart (via the pulmonary artery) for the lungs is shunted away from the lungs and returned to the greatest of arteries (the aorta). The shunt is through a short vessel called the ductus arteriosus. When the shunt is open, it is said to be patent (pronounced pa'tent). The patent ductus arteriosus (PDA) usually closes at or shortly after birth and blood is permtted from that moment on to course freely to the lungs. If the ductus stays open (patent), flow reverses and blood from the aorta is shunted into the pulmonary artery and recirculated through the lungs. The PDA may close later spontaneously (on its own) or need to be ligated (tied off) surgically. (12 Dec 1998) |
| arterial capillary | A capillary opening from an arteriole or metarteriole. (05 Mar 2000) |
| arterial circle of cerebrum | An anastomotic "circle" of arteries (roughly pentagonal in outline) at the base of the brain, formed, sequentially and in anterior to posterior direction, by the anterior communicating artery, the two anterior cerebral, the two internal carotid, the two posterior communicating, and the two posterior cerebral arteries. Synonym: circulus arteriosus cerebri, circle of Willis. (05 Mar 2000) |
| arterial cone | The left or anterosuperior, smooth-walled portion of the cavity of the right ventricle of the heart, which begins at the supraventricular crest and terminates in the pulmonary trunk. Synonym: arterial cone, pulmonary cone, pulmonary conus. (05 Mar 2000) |

| arterial embolism | <cardiology, physiology> A sudden interruption in arterial blood flow to an organ or body part (extremity). The blockage is caused by a blot clot or atherosclerotic plaque that has moved through the arterial circulation from one position to another. The resulting mechanism is the same regardless of cause or location. Oxygen deprivation to the tissues distal to the occlusion become ischaemic and die (necrosis). Atrial fibrillation is a risk factor for arterial embolism due to the release of blood clots from the fibrillating heart. Blood vessel injury and increased levels of platelets can also be a risk for arterial embolism. Symptoms vary with location, but pain, coolness to an extremity and a absent or diminished pulse are common in the case of an extremity embolism. Treatment is often surgical or involves the use of blood clot dissolving medications (for example streptokinase) delivered selectively to the site of the blockage. (17 Oct 1997) |
| arterial flap | A flap that includes a direct specific artery within its longitudinal axis. Synonym: arterial flap. (05 Mar 2000) |
| arterial forceps | A locking forceps with sloping blades for grasping the end of a blood vessel until a ligature is applied. (05 Mar 2000) |
| arterial grooves | Branching grooves on the interior surface of the cranial vault in which the meningeal arteries course, the most prominent of which are related to branches of the middle meningeal artery. Synonym: sulci arteriosi. (05 Mar 2000) |
| arterial hyperaemia | active hyperaemia |
| arterial hypotension | See: hypotension. (05 Mar 2000) |
| arterial ligament | The remains of the ductus arteriosus. Synonym: arterial ligament, Botallo's ligament. (05 Mar 2000) |
| arterial line | An intra-arterial catheter. (05 Mar 2000) |
