homeostasis mean?

Answer 1

1. the tendency of a system, esp. the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus tending to disturb its normal condition or function.
2. Psychology. a state of psychological equilibrium obtained when tension or a drive has been reduced or eliminated.

Answer 2

The first 3 answerers were correct (and very good). I like to think of homeostasis as a teeter-totter and both players in the middle position (for a bit) . It's usually compared to the thermostat in a house, trying to maintain a "steady state". It's simplistic in that one might think there are only two factors in this balancing act. There many factors are involved in this balancing. When I began a study of kidney functions, I thought I was in swamp with a bottom that seemed unfathomable to me. The harder question to me was why.
Many of the words employed in science are repeated so often that it is very worthwhile to understand which will enable a person to guess what is being described, and the idea that (was, is) trying to be conveyed. Thus: **** = same; Statis = state or level (status) or equilibrium. Hope this helps you in the future more than just now.

Answer 3

It means keeping the internal conditions of the body constant. Sweating when you are hot, shivering when you are cold, are homeostatic effects which help keep your bodys temperature constant. Urinating a little or a lot and feeling thirsty control how much water there is inside you. Anything you can think of, hormone levels, oxygen concentrations in the blood, the amount of nutrients inside you, are all kept under strict control as your body operates the best under fairly strict windows.

There is a lot to be understood about homeostasis and it covers a wide range of physiological and behavioural adaptations. The Mediterranean phenomena of the siesta is a behavioural adaptation to keeping cool during the heat of the day, wheras sweating is physiological.

Answer 4

Homeostasis is the maintenance of relatively steady state conditions in the body. One of the main methods is the use of negative feedback systems.

Answer 5

Homeostasis is the property of an open system, especially living organisms, to regulate its internal environment to maintain a stable, constant condition, by means of multiple dynamic equilibrium adjustments, controlled by interrelated regulation mechanisms.
