Question

How does homeostasis in the drives as tissue needs.?

Answer 1

• The body always tends to maintain a state of equilibrium called “Homeostasis”- in many of its internal physiological processes.This balance is very essential for the normal life.
• Homeostasis helps to maintain internal physiological processes at optimal levels. The nutritional level, fluid level, temperature level, etc., are maintained at certain optimal level or homeostasis levels. When there is some variation in these levels the individual is motivated for restoring the state of equilibrium.
• If the imbalance in the body is caused by tissue need i.e. body's need for food or drink,the hungry person needs to do something to obtain food or water. We develop hunger motive in order to maintain homeostasis. This is indicated by contraction of stomach muscles causing some pain or discomfort called hunger pangs.When the water level in the body decreases we develop motive to drink water.Usually thirst motive is indicated by dryness of mouth.
• This is where the concept of homeostatic drive becomes important.Tissue need leads to internal imbalance, which leads to homeostatic drive, which leads to appropriate behaviour, which leads to restoration of internal balance, which leads to drive reduction. The internal environment requires a regular supply of raw materials from the external world.
