Blood pressure regulation: basic concepts.

摘要: In this paper we have attempted to explain the difference between proportional pressure control systems and renal-blood volume-pressure mechanism, which is an infinite gain system. Because of kidney mechanism has capability returning arterial all way back leve. Furthermore, can override other mechanisms because its extreme capability. On hand, volume for itself be controlled by many factors. These factors are said change "set-point" level renal system, then system automatically brings set-point level. It especially noteworthy, however, that some play roles in short-term control-such as heart strength, vascular capacity, total peripheral resistance-will not alter long-term (unless they concurrently mechanism).
