| anaemic anoxia | A term formerly considered synonymous with anaemic hypoxia, but now reserved for extremely severe cases in which oxygen is almost completely lacking. (05 Mar 2000) |
|---|---|
| anoxia | <physiology> A total lack of oxygen, often used interchangeably with hypoxia to mean a reduced supply of oxygen to the tissues. (18 Nov 1997) |
| anoxia neonatorum | Any anoxia observed in newborn infants. (05 Mar 2000) |
| anoxic anoxia | A term formerly considered synonymous with hypoxic hypoxia, but now reserved for extremely severe cases in which oxygen is almost completely lacking. (05 Mar 2000) |
| cerebral anoxia | A reduced supply of oxygen to the brain. (12 Dec 1998) |
| histotoxic anoxia | Poisoning of the respiratory enzyme systems of the tissues, as in the inhibition of cytochrome oxidase by cyanides; owing to the inability of tissue cells to utilise oxygen, its tension in arterial and capillary blood is usually greater than normal. (05 Mar 2000) |
| stagnant anoxia | Stagnant hypoxia severe enough to result in the absence of oxygen in tissues. (05 Mar 2000) |
| diffusion anoxia | Diffusion hypoxia severe enough to result in the absence of oxygen in alveolar gas. (05 Mar 2000) |
| oxygen affinity anoxia | Anoxia due to inability of haemoglobin to release oxygen. (05 Mar 2000) |
| foetal anoxia | Foetal oxygen deficiency. (12 Dec 1998) |
| adenoid tissue | A structure found within the lymphatic system that consists of lymphocytes within a network of fibres. (09 Oct 1997) |
| adipose tissue | <anatomy> Connective tissue that has been specialised to store fat. See: adipocyte. (25 Jun 1999) |
| aerenchymous tissue | A type of plant tissue in which cells are unusually large, resulting in large air spaces in the plant organ, such tissues are often referred to as spongy and usually provide increased buoyancy. (09 Oct 1997) |
| areolar tissue | Loose, irregularly arranged connective tissue that consists of collagenous and elastic fibres, a protein polysaccharide ground substance, and connective tissue cells (fibroblasts, macrophages, mast cells, and sometimes fat cells, plasma cells, leukocytes, and pigment cells). (05 Mar 2000) |
| bone tissue | A connective tissue, the matrix of which consists of collagen fibres and ground substance and in which are deposited calcium salts (phosphate, carbonate, and some fluoride) in the form of an apatite. Synonym: bone tissue. (05 Mar 2000) |
