|---|---|---|---|
| 설명 | 세포성분 및 분자성분의 복합체계로서, 이의 일차기능은 자기(self)를 비자기(not self)로부터 구별하고 외부생물 또는 물질에 대해 방어하는 것이다. 일차적인 세포성분은 림프구와 큰포식세포이며 일차적인 분자성분은 항체와 림포카인이다. |

| 영문 | urinary system | 한글 | 비뇨기계통 |
|---|---|---|---|
| 설명 | 비뇨기계통이라하면 콩팥으로부터 시작해서 요관, 방광, 요도에 이르는 일련의 오줌생성 및 저장, 배설기관을 일컫는다. 콩팥은 길이 약 2.5cm, 폭 약 5.1cm, 두께 약 2.5cm, 무게 약 120~160gm으로서, 내측에 콩팥문이 있어 혈관, 신경, 요관이 출입하고 있다. 콩팥은 속질과 겉질로 이루어져 있으며 수질은 10~15개의 추체(오줌을 모으는 역할)를 형성하고 겉질은 약 100만개의 콩팥단위으로 구성되어 있다. 요세관은 토리쪽뇨세관, 헨레고리, 먼쪽뇨세관, 집합관으로 형성되어 있으며, 추체와 술잔, 깔때기를 거쳐 요관으로 연결된다. 콩팥은 혈액을 여과하여 신체 신진대사의 최종산물을 오줌의 형태로 배설하며, 세포외액(extracellular fluid)의 전해질농도를 조절한다. 콩팥에서 형성된 오줌는 요관을 거쳐 방광에서 저장되고 있다가 적당한 시기가 되면 요도를 통해 외계로 배출된다. |

| HCN | Hydrogen Cyanide; 청산 |
| H2S | Hydrogen Sulfate; 황화수소 |
| pH | 수소이온농도지수; Hydrogen Ion or Degree of Acidity; 수소지수, 산도 |
| hydrogen bromide | HBr;a colourless gas that has a very irritating odour and fumes in moist air; in aqueous solution, it is hydrobromic acid. Hydrogen chloride, HCl;a very soluble gas which, in solution, forms hydrochloric acid. (05 Mar 2000) |
|---|---|
| hydrogen carrier | A molecule that, in conjunction with a tissue enzyme system, carries hydrogen from one metabolite (oxidant) to another (reductant) or to molecular oxygen to form H2O. Synonym: hydrogen acceptor. (05 Mar 2000) |
| hydrogen cyanide | <chemical> Hydrogen cyanide (hcn). A toxic liquid or colourless gas. It is found in the smoke of various tobacco products and released by combustion of nitrogen-containing organic materials. Pharmacological action: poisons. Chemical name: Hydrocyanic acid (12 Dec 1998) |
| hydrogen dehydrogenase | <enzyme> Hoxf, hoxh, hoxu, and hoxy from rhodococcus opacus encode the alpha-, beta-, gamma-, and delta-subunits, respectively Registry number: EC 1.12.1.2 Synonym: hydrogen-nad+ oxidoreductase, nad-reducing hydrogenase, hoxf gene product, hoxu gene product, hoxy gene product, hoxh gene product (26 Jun 1999) |
| hydrogen dioxide | <chemical> Hydrogen peroxide is produced by vertebrate phagocytes and is used in bacterial killing (the myeloperoxidase halide system). (05 May 1997) |
| hydrogen donor | A metabolite from which hydrogen is removed (by a dehydrogenase system) and transferred by a hydrogen carrier to another metabolite, which is thus reduced. (05 Mar 2000) |
| hydrogen electrode | The ultimate standard of reference in all pH determinations, limited and technically difficult to use, consisting of a piece of spongy platinum black partly immersed in a solution in a small glass tube; the tube above the solution is filled with hydrogen gas that is bubbled through the solution and absorbed by the platinum; the electrode thus measures the potential between H2 and H+, the "standard" potential of which (1 atmosphere, 1 molar) is taken as zero; hence, the hydrogen electrode potential measures [H+] or pH. (05 Mar 2000) |
| hydrogen embrittlement | <physics> A decrease in the fracture strength of metals (embrittlement) due to the incorporation of hydrogen within the metal lattice. (09 Oct 1997) |
| hydrogen exponent | The logarithm of the hydrogen ion concentration in blood or other fluid; its negative is the pH of that fluid. (05 Mar 2000) |
| hydrogen ion | A hydrogen atom minus its electron and therefore carrying a unit positive charge (i.e., a proton); in water, it combines with a water molecule to form hydronium ion, H3O+. (05 Mar 2000) |
| hydrogen number | The quantity of hydrogen that 1 g of fat will absorb; it is a measurement of the amount of unsaturated fatty acids in the fat. See: iodine number. (05 Mar 2000) |
| hydrogen peroxide | <chemical> Hydrogen peroxide is produced by vertebrate phagocytes and is used in bacterial killing (the myeloperoxidase halide system). (05 May 1997) |
| hydrogen phosphide | <chemistry> A colourless gas, PH3, analogous to ammonia, and having a disagreeable odour resembling that of garlic. Synonym: hydrogen phosphide, and formerly, phosphureted hydrogen. It is the most important compound of phosphorus and hydrogen, and is produced by the action of caustic potash on phosphorus. It is spontaneously inflammable, owing to impurities, and in burning produces peculiar vortical rings of smoke. Source: Websters Dictionary (01 Mar 1998) |
| hydrogen-potassium-exchanging atpase | <enzyme> An enzyme isolated from the gastric mucosa that catalyses the hydrolysis of ATP coupled with the exchange of hydrogen and potassium ions across the cell wall. Chemical name: ATP phosphohydrolase (H+/K+-transporting) Registry number: EC 3.6.1.36 (12 Dec 1998) |
| hydrogen pump | Molecular mechanism for acid secretion from gastric parietal cells based on the activity of a H+-K+-ATPase. (05 Mar 2000) |
