Hans-Günther Rossbach,Martin Wellenreuthere visceral control centers are concerned with the maintenance of a constant internal environment. All of the visceral systems—cardiovascular, endocrine, gastrointestinal, metabolic, renal, reproductive, and respiratory—are affected by the activity of these neural control centers.

Friederike Heinzel,Annedore Prengele up of intracellular and extracellular compartments, which may be subdivided as shown in Table 12.1. Intracellular water comprises 70% of total body water; however this varies depending on the subject’s age, and the amount of lean body tissue (Table 12.2). Body water is higher in lean than in fatty

The principal chemical constituents of blood are Na., K., P, Ca., glucose, the plasma proteins (albumin, globulin and fibrinogen). These proteins am

This system is composed of specialized muscle cells that have the property of automaticity, and their rate of conduction of an electrical impulse is faster than ordinary atrial and ventricular muscle. The impuls

According to the first law of thermodynamics, energy can neither be created nor destroyed. Therefore organisms must obtain energy in useful form from
