Physiological needs - Thirst - physiological regulation

4 important questions on Physiological needs - Thirst - physiological regulation

What are the two water sources in the body?

  1. Intracellular (in the cel)
  2. extracellular (outside the cel)

Thirst comes from a deficit in water. This can be a deficit inside the cells or outside the sells. According to the double depletion model of thirst activation, Which two types of thirst exist?

An intracellular deficit causes osmometric thirst
An extracellular deficit causes volumetric thirst

What is the primary cause of thirst?

Osmometric thirst, which is a result of dehydrated cells

Thirst satiety is dependent of a negative feedback mechanism, where can we find this negative feedback?

The cells have a negative feedback system that sends a signal to stop drinking when the cells are hydrated.
