Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the organism's ability to maintain steady (stable) internal conditions despite changes in the external environment.

Front

What role do receptors play in homeostasis?

Back

Receptors are body parts that sense changes inside the organism, allowing it to respond to internal and external stimuli.

Front

What is the control center in the feedback loop responsible for?

Back

The control center, such as the hypothalamus in the brain, is responsible for processing information from receptors and coordinating the body's response.

Front

What is an example of a response to an internal stimulus?

Back

An example of a response to an internal stimulus is eating food when the body signals hunger.

Front

How does sweating help maintain homeostasis?

Back

Sweating helps maintain homeostasis by cooling the body down when temperature increases, thus restoring stable internal conditions.

Front

What is a stimulus in the context of homeostasis?

Back

A stimulus is a change in the internal or external environment that triggers a response in the body to maintain homeostasis.

Front

What happens when body temperature increases during exercise?

Back

When body temperature increases during exercise, receptors sense the change, and the hypothalamus activates mechanisms like sweating to cool the body down.

Front

What is the importance of feedback loops in homeostasis?

Back

Feedback loops are important in homeostasis as they help regulate physiological processes by providing a mechanism for the body to respond to changes.

Front

What is the difference between positive and negative feedback in homeostasis?

Back

Negative feedback reduces the output or activity of a system to return to a set point, while positive feedback amplifies responses to push a system away from its starting state.

Front

What is an internal stimulus?

Back

An internal stimulus is a change that occurs within the body, such as hunger or thirst, prompting a physiological response.
