| noradrenergic system | The system of nerve cells that uses noradrenaline as its neurotransmitter. (13 Nov 1997) |
|---|---|
| delivery system | A manmade system with the purpose of delivering a drug or another chemical directly into a cellular target, such as a via a manmade vesicle called a liposome. (09 Oct 1997) |
| sympathetic nervous system | <anatomy, physiology> One of the two divisions of the vertebrate autonomic nervous system (the other being the parasympathetic nervous system). The sympathetic preganglionic neurons have their cell bodies in the thoracic and lumbar regions of the spinal cord and connect to the paravertebral chain of sympathetic ganglia. Innervate heart and blood vessels, sweat glands, viscera and the adrenal medulla. most sympathetic neurons, but not all, use noradrenaline as a post ganglionic neurotransmitter. (19 Jan 1998) |
| dermal system | Dermoid system, the skin and its appendages, the nails and hair. (05 Mar 2000) |
| system | <biology, ecology> A group of related natural objects or forces within a defined zone, a regularly interacting or interdependent group of items forming a unified whole, a more general and less rigorous term than ecosystem. (09 Oct 1997) |
| system of macrophages | A widely distributed collection of both free and fixed macrophages derived from bone marrow precursor cells by way of monocytes; their substantial phagocytic activity is mediated by immunoglobulin and the serum complement system. In both connective and lymphoid tissue, they may occur as free and fixed macrophages; in the sinusoids of the liver, as Kupffer cells; in the lung, as alveolar macrophages; and in the nervous system, as microglia. Synonym: system of macrophages. (05 Mar 2000) |
| system, parasympathetic nervous | : A part of nervous system that slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. The parasympathetic nervous system together with the sympathetic nervous system (that accelerates the heart rate, constricts blood vessels, and raises blood pressure) constitute the autonomic nervous system. (12 Dec 1998) |

| diagnostic techniques, respiratory system | Methods and procedures for the diagnosis of diseases of the respiratory tract or its organs. It includes respiratory function tests. (12 Dec 1998) |
| dopaminergic system | The system of nerve cells that uses dopamine asits neurotransmitter. (22 May 1997) |
| duffy blood-group system | A blood group consisting mainly of the antigens fy(a) and fy(b), determined by allelic genes, the frequency of which varies profoundly in different races; amorphic genes are common. (12 Dec 1998) |
| I blood-group system | A blood group related both to the abo and p systems that includes several different antigens found in most people on erythrocytes, in milk, and in saliva. The antibodies react only at low temperatures. (12 Dec 1998) |
| imhoff treatment system | In waste water treatment, a tank without aeration or oxygenation where solids settle out. The solids are digested in a separate compartment in the bottom. (05 Dec 1998) |
| immune system | <immunology> The body system, made up of many organs and cells, that defends the body against infection, disease and foreign substances. The immune system is often stimulated in specific ways to fight cancer cells. (16 Dec 1997) |
| indicator system | In in vitro immunological tests, a combination of reagents used to determine the degree to which immunological reagents have combined (e.g., sensitised erythrocytes in complement-fixation tests; enzyme and substrate in enzyme-linked immunosorbent assays). (05 Mar 2000) |
