Homeostasis Review

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is a stimulus in the context of homeostasis?

Back

A stimulus is any change in the environment that can provoke a response from an organism.

Front

What is a response in the context of homeostasis?

Back

A response is the action or change in behavior that occurs as a result of a stimulus.

Front

Which organ in the human body is primarily responsible for maintaining homeostasis?

Back

The brain is primarily responsible for maintaining homeostasis by processing information and coordinating responses.

Front

What role do receptors play in homeostasis?

Back

Receptors detect changes in the environment and send signals to the control center to initiate a response.

Front

What is the difference between positive and negative feedback mechanisms?

Back

Negative feedback mechanisms counteract changes to return to a set point, while positive feedback mechanisms amplify changes to push a process to completion.

Front

How does osmosis contribute to homeostasis?

Back

Osmosis helps maintain the balance of water and solutes in cells, which is crucial for cellular function and overall homeostasis.

Front

What is the significance of chloroplasts in plant cells?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the role of the control center in homeostasis?

Back

The control center processes information from receptors and determines the appropriate response to maintain homeostasis.

Front

How do effectors function in the homeostatic process?

Back

Effectors are organs or cells that carry out the response determined by the control center to restore balance.
