Stores, sumps, and sinks
1980
McLaren, Donald S.
Accumulations of substances in the body may be classified as stores, sumps, or sinks, according to such characteristics as their forms, sites, and amounts. Their sources and possible harmful effects must also be considered when classifying accumulations. Glycogen accumulation from carbohydrate appears to be a store and is a short-term energy reserve. Harmful effects occur only in glyocogen "storage" diseases. Any excess intake of energy is stored as fat; a prolonged excess of energy intake can enlarge adipose tissues into sumps and sinks. Although protein does not seem to accumulate in a harmful or useless way, its role as a store is limited except in early pregnancy and starvation. Iron accumulations may act as stores, sumps, or sinks. Muscle tissues contain locally active calcium stores. The vitamin A in the liver is regarded as a store.
