The term homeostasis was first coined by a psychologist named Walter Cannon in 1926. 1 The term, homeostasis, refers to an organism’s ability to regulate various physiological processes to keep internal states steady and balanced. These processes take place mostly without our conscious awareness.
Which is the best definition of homeostasis?
Homeostasis: A property of cells, tissues, and organisms that allows the maintenance and regulation of the stability and constancy needed to function properly. … Other homeostatic mechanisms, for example, permit the maintenance of body temperature within a narrow range.
What is homeostasis Definition & Examples?
The definition of homeostasis is the ability or tendency to maintain internal stability in an organism to compensate for environmental changes. An example of homeostasis is the human body keeping an average temperature of 98.6 degrees.
What are 3 examples of homeostasis?
Examples of Homeostasis
- Ratios of water and minerals.
- Body temperature.
- Chemical levels.

Homeostasis. A physiological state of equilibrium or balance. Homeostasis, refers to an organism’s ability to adjust its physiological processes to maintain a steady. internal balance or equilibrium.
What’s an example of homeostasis?
Humans’ internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). … That’s an example of homeostasis being maintained.
What is homeostasis and why is it important?
Homeostasis maintains optimal conditions for enzyme action throughout the body, as well as all cell functions. It is the maintenance of a constant internal environment despite changes in internal and external conditions. In the human body, these include the control of: blood glucose concentration.
What are the three types of homeostasis?
Generally, there are three types of homeostatic regulation in the body, which are:
- Thermoregulation. Thermoregulation is the process occurring inside the body that is responsible for maintaining the core temperature of the body. …
- Osmoregulation. …
- Chemical regulation.
What does homeostasis literally mean?
It means keeping things constant and comes from two Greek words: ‘homeo,’ meaning ‘similar,’ and ‘stasis,’ meaning ‘stable. ‘ A more formal definition of homeostasis is a characteristic of a system that regulates its internal environment and tends to maintain a stable, relatively constant condition of properties.
What is another name for homeostasis?
equilibrium, balance, evenness, stability, equanimity, equipoise.
What is the normal homeostasis?
Body temperature control in humans is one of the most familiar examples of homeostasis. Normal body temperature hovers around 37 °C (98.6 °F), but a number of factors can affect this value, including exposure to the elements, hormones, metabolic rate, and disease, leading to excessively high or low body temperatures.
What is homeostasis process?
Definition: Homeostasis is the ability to maintain a constant internal environment in response to environmental changes. … Examples of homeostatic processes in the body include temperature control, pH balance, water and electrolyte balance, blood pressure, and respiration.
Is shivering An example of homeostasis?
Shivering is one of the many automatic and subconscious functions that the body performs to regulate itself. Other so-called homeostatic functions include the adjustment of breathing rates, blood pressure, heart rate and weight regulation. Shivering is essentially the body’s last-ditch effort to keep itself warm.
What is homeostasis and why is it important quizlet?
Homeostasis is important because all living organisms have to have a stable internal environment to function normally. Organisms that are unable to balance its internal with its external, can die.
What is homeostasis in the human body?
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
What is the physiological state that motivates you to satisfy a need?
drive – reduction theory the idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need.
