Termination of drinking: satiation

Speeds of swallowing water differ among species, for example, in the dog and rat. Alimentary factors predominate in the termination of drinking. Parenteral water avoids alimentary factors, yet can also lead to delayed satiation. Central factors of termination are also recognized, especially in the neurohypophysis. Kinetics of various intakes (food, sodium, oxygen, heat) show analogous patterns of satiation or saturation. Such intakes have in common the dimensions of clearances of deficits.
