| 영문 | blood gas | 한글 | 혈액가스, 혈액기체 |
|---|---|---|---|
| 설명 | 혈액 속에 용해되어 있는 산소, 이산화탄소, 질소 따위의 기체. 혈액의 산성-염기성의 정도를 측정할 수 있다. |

| 영문 | blood test | 한글 | 혈액검사 |
|---|---|---|---|
| 설명 | 혈액형이나 질병 유무 따위를 알기 위하여 피를 뽑아 행하는 검사. 몸 전체의 장기나 조직에 병터가 있으면 이들 성분에 변화가 있게 되어 진단에 큰 도움을 준다. |

| 영문 | blood-brain barrier | 한글 | 혈액뇌장벽 |
|---|---|---|---|
| 설명 | 혈액으로부터 뇌로는 지질용해성이 높은 약물밖에 이행되지 않는다. 수용성의 약물을 뇌로 이행되지 않게 하고 있는 것이 혈액뇌장벽이며 뇌의 모세혈관 내피세포, 모세혈관 주위의 세포가 장벽이 되고 있다. 물질교환은 수동확산에 의해 이루어지지만, 뇌의 생리적 활동에 필요한 물질은 이온형이라도 담체를 통해 이행된다. |

| 영문 | blood volume | 한글 | 혈액량 |
|---|---|---|---|
| 설명 | 체내에 존재하는 혈액의 총량으로서, 보통 리터 또는 체중 1kg에 대하여 리터수로 표시한다. |

| 영문 | blood urea nitrogen | 한글 | 혈액요소질소 |
|---|---|---|---|
| 설명 | 요소는 아미노산의 탈아미노에 의해 생긴 암노니아와 탄산가스로부터 간에서 합성된다. 혈중에서는 혈장과 혈구의 물성분 안에 함유되어 있다. 혈액요소질소는 콩팥토리에서 여과되며 일부 요세관에서 재흡수되고, 나머지가 오줌중에 배설된다. 따라서 혈액요소질소는 콩팥기능의 저하에 따라 증가되지만, 식사단백질 섭취량, 조직붕괴, 위장관 출혈 등과 탈수 등 순환혈액량의 이상으로 변동된다. |

| blood catecholamine | <investigation> The measurement of noradrenaline and adrenaline in the blood. Often these same catecholamines can be measured in the urine. Elevations may be seen in pheochromocytoma or neuroblastoma. Normal blood levels of adrenaline should be: 20 ng/ml and normal blood levels of noradrenaline should be 60 ng/ml. (05 Jan 1998) |
|---|---|
| blood cell | <haematology> There are three main types of cell in the blood stream. The red cell, which carries oxygen, the white cell, which fights infections and the platelet, which helps prevent bleeding. The correct balance between each cell type must be maintained for the body to remain healthy. (13 Nov 1997) |
| blood cell count | A count of the number of leukocytes and erythrocytes per unit volume in a sample of venous blood. A complete blood count (cbc) also includes measurement of the haemoglobin, haematocrit, and erythrocyte indices. (12 Dec 1998) |
| blood-cerebrospinal fluid barrier | A barrier located at the tight junctions which surround and connect the cuboidal epithelial cells on the surface of the choroid plexus; capillaries and connective tissue stroma of the choroid do not represent a barrier to protein tracers or dyes. (05 Mar 2000) |
| blood circulation | The course of the blood from the heart through the arteries, capillaries, and veins back again to the heart. (05 Mar 2000) |
| blood circulation time | Determination of the shortest time interval between the injection of a substance in the vein and its arrival at some distant site in sufficient concentration to produce a recognizable end result. It represents approximately the inverse of the average velocity of blood flow between two points. (12 Dec 1998) |
| blood clot | <haematology> The conversion of blood from a liquid form to solid through the process of coagulation. A thrombus is a clot which forms inside of a blood vessel. If that clot moves inside the vessel it is referred to as an embolus (embolism). The presence of atherosclerotic plaque lining blood vessel walls is a significant stimulus for clot formation. (27 Sep 1997) |
| blood clotting factor | <haematology> Any of a number of different protein factors which, when acting together, can form a blood clot shortly after platelets have broken at the site of the wound. The factors have Roman numeral names, like VII, VIII, IX, X, XI, and XIII. Defects in the genes which code for any of these factors result in genetic diseases like haemophilia, which results from a defect in the gene for factor VIII or IX. (09 Oct 1997) |
| blood coagulation | The sequential process by which the multiple coagulation factors of the blood interact, ultimately resulting in the formation of an insoluble fibrin clot; it may be divided into three stages: stage 1, the formation of intrinsic and extrinsic prothrombin converting principle; stage 2, the formation of thrombin; stage 3, the formation of stable fibrin polymers. (12 Dec 1998) |
| blood coagulation factor inhibitors | Substances, usually endogenous, that act as inhibitors of blood coagulation. They may affect one or multiple enzymes throughout the process. As a group, they also inhibit enzymes involved in processes other than blood coagulation, such as those from the complement system, fibrinolytic enzyme system, blood cells, and bacteria. (12 Dec 1998) |
| blood coagulation factors | Endogenous substances, usually proteins, that participate in the blood coagulation process. (12 Dec 1998) |
| blood coagulation tests | Laboratory tests for evaluating the individual's clotting mechanism. (12 Dec 1998) |
| blood component removal | Any procedure in which blood is withdrawn from a donor, a portion is separated and retained and the remainder is returned to the donor. (12 Dec 1998) |
| blood component transfusion | The transfer of blood components such as erythrocytes, leukocytes, platelets, and plasma from a donor to a recipient or back to the donor. This process differs from the procedures undertaken in plasmapheresis and types of cytapheresis (plateletpheresis and leukapheresis) where, following the removal of plasma or the specific cell components, the remainder is transfused back to the donor. (12 Dec 1998) |
| blood corpuscle | <haematology> There are three main types of cell in the blood stream. The red cell, which carries oxygen, the white cell, which fights infections and the platelet, which helps prevent bleeding. The correct balance between each cell type must be maintained for the body to remain healthy. (13 Nov 1997) |
