| 영문 | hepatic portal system | 한글 | 간문맥계 |
|---|---|---|---|
| 설명 | 위, 작은창자이나 큰창자에서 영양분을 흡수하기 위한 모세혈관조직은 모두 간으로 연결된다. 즉 소화기에 흡수한 영양분이 가득한 피는 모두 간으로 연결되는데 이것을 문맥계라고 한다. |

| 영문 | sympathetic nervous system | 한글 | 교감신경계 |
|---|---|---|---|
| 설명 | 자율신경계의 일종으로 내장기능을 주로 항진시켜 활동을 증가시키는 기능을 가진다. 자율신경계의 다른 계열인 부교감신경계는 반대로 내장기능을 억제시켜 에너지를 비축하는 기능을 가진다. 자율신경계의 해부학적 특성은 신경이 중추신경계에서 나와 목표장기에 도달하기 전에 한번의 시냅스(synapse)를 이룬다는 점이며, 따라서 자율신경계는 두 개의 신경(시냅스를 이루기 전의 절전신경과 이룬 후의 절후신경)으로 구성된다. 자율신경계중 교감신경계는 중추신경계 즉 척수 부근의 교감신경절(sympathetic ganglion)에서 시냅스가 일어나고, 부교감 신경계는 중추신경계에서 멀리 떨어진 목표 장기부근의 신경절(ganglion)에서 시냅스가 일어나는 점이 다르다. |

| 영문 | musculoskeletal System | 한글 | 근골격계 |
|---|---|---|---|
| 설명 | 근육과 이들 근육이 붙어서 같이 활동을 수행하는 골격(뼈를 통털어 말함)을 함께 부르는 말. 따라서 여기의 근육은 모두 가로무늬근에 속하며, 수의적으로 움직일 수 있다. |

| 영문 | muscular system | 한글 | 근육계통 |
|---|---|---|---|
| 설명 | 근육에 의해 이루어진 하나의 계통을 임의적으로 나누어 부른 말. |

| redox system | <enzyme> An enzyme system in the tissues by which oxidation and reduction proceed simultaneously through the transference of hydrogen or of one or more electrons from one metabolite to another. See: oxidation-reduction. Synonym: redox system. (05 Mar 2000) |
|---|---|
| vestibular system | <anatomy> The organ of the inner ear containing several three semicircular ducts at right angles to one another, helps keep the body balanced. (09 Oct 1997) |
| caudal neurosecretory system | urohypophysis |
| glandular system | All the glands of the body collectively. (05 Mar 2000) |
| visceral nervous system | <anatomy> Neurons that are not under conscious control, comprising two antagonistic components, the sympathetic and parasympathetic nervous systems. The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g., of the gut), and glands. The autonomic nervous system has two divisions: 1. The sympathetic nervous system that accelerates the heart rate, constricts blood vessels, and raises blood pressure. 2. The parasympathetic nervous system slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. (03 Jul 1999) |
| reminder system | <psychology> Systems used to prompt or aid the memory. The systems can be computerised reminders, colour coding, telephone calls, or devices such as letters and postcards. (12 Dec 1998) |
| cell-free system | <cell culture, molecular biology> Any system in which a normal cellular reaction is reconstituted in the absence of cells for example in vitro translation systems that will synthesise protein from mRNA using a lysate of rabbit reticulocytes or wheat germ. A fractionated cell extract that maintains a biological function. A subcellular fraction isolated by ultracentrifugation or other separation techniques must first be isolated so that a process can be studied free from all of the complex side reactions that occur in a cell. The cell-free system is therefore widely used in cell biology. (12 Dec 1998) |
| renal portal system | An arterial portal system, in which efferent glomerular arterioles receive blood from the capillaries of the renal glomeruli and carry it to the peritubular capillary plexus surrounding the proximal and distal convoluted tubules. Synonym: hypothalamohypophysial portal system. (05 Mar 2000) |
| p blood-group system | A blood group related to the abo, lewis and I systems. at least five different erythrocyte antigens are possible, some very rare, others almost universal. Multiple alleles are involved in this blood group. (12 Dec 1998) |
| renin-angiotensin-aldosterone system | The hormones, renin, angiotensin, and aldosterone work together to regulate blood pressure. A sustained fall in blood pressure causes the kidney to release renin. This is converted to angiotensin in the circulation. Angiotensin then raises blood pressure directly by arteriolar constriction and stimulates adrenal gland to produce aldosterone which promotes sodium and water retention by kidney, such that blood volume and blood pressure increase. (05 Mar 2000) |
| renin-angiotensin system | <physiology> A system consisting of renin, angiotensin-converting enzyme, and angiotensin II. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming angiotensin I. The converting enzyme contained in the lung acts on angiotensin I in the plasma converting it to angiotensin II, the most powerful directly pressor substance known. It causes contraction of the arteriolar smooth muscle and has other indirect actions mediated through the adrenal cortex. (25 Jun 1999) |
| centimeter-gram-second system | The scientific system of expressing the fundamental physical units of length, mass, and time, and those units derived from them, in centimeters, grams, and seconds; currently being replaced by the International System of Units based on the meter, kilogram, and second. (05 Mar 2000) |
| reproductive system | In women, the organs that are directly involved in producing eggs and in conceiving and carrying babies. (12 Dec 1998) |
| pedal system | Efferent fibres connecting the forebrain with more caudal structures. (05 Mar 2000) |
| central nervous system | <anatomy, neurology> Pertaining to the brain, cranial nerves and spinal cord. It does not include muscles or peripheral nerves. In invertebrates, the central nervous system is composed of the segmental ganglia of the ventral nerve cord together with the fused ganglia or brain at the anterior end. Acronym: CNS (12 Jan 1998) |
