Question

Define homeostatic mechanism in a living organism.

Answer 1

Hint: The homeostatic mechanisms are the ability to maintain a stable condition inside the living body. This is achieved by several biophysical, biochemical processes, hormonal secretions, and the related metabolic modifications.

Complete answer: When the sweat evaporates from the skin, it uses up some of the body's heat energy. It helps to keep the body's internal temperature constant. When the body's internal environment is stable, the condition is called homeostasis. The word homeostasis, from the Greek words for "same" and "steady," refers to any process that the living things use to actively maintain fairly stable conditions necessary for survival. The term was coined by the great physician Walter Cannon. Homeostasis has found useful applications in the social sciences. The homeostasis typically involves the negative feedback loops that counteract the changes of various properties from their target values, also known as the setpoints. The homeostatic control mechanisms have at least three interdependent components: a receptor, the integrating center, and the effectors. The receptor senses the environmental stimuli, sending the information to the integrating center. The integrating center, generally a region of the brain called the hypothalamus, signals an effector to respond to the stimuli.

Note: The human body includes mechanisms that can help regulate the body; this includes the organs, glands, tissues, and cells. The adjusting of these enables the body to constantly be in a steady state. The main mechanisms of homeostasis are body temperature, body fluid composition, blood sugar, gas concentrations, and blood pressure.
