Body Orientation- Homeostasis

Front

What is the correct order of elements in a control system?

Back

stimulus, receptor, afferent pathway, control center, efferent pathway, effector, response

Front

Which element of a control system detects a change?

Back

receptor

Front

What is considered a normal body temperature in Celsius?

Back

37 degrees Celsius

Front

What do positive feedback systems do?

Back

They operate in such a way that the initial stimulus is enhanced and increases.

Front

Define homeostasis.

Back

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

Front

What is a receptor in the context of homeostasis?

Back

A receptor is a sensory structure that detects changes in the environment (stimuli) and sends information to the control center.

Front

What role does the control center play in a control system?

Back

The control center processes information received from receptors and determines the appropriate response.

Front

What is an effector in a control system?

Back

An effector is a muscle or gland that carries out the response determined by the control center.

Front

What is the difference between negative and positive feedback mechanisms?

Back

Negative feedback mechanisms reduce the effect of the initial stimulus, while positive feedback mechanisms enhance it.

Front

Give an example of a negative feedback mechanism in the body.

Back

Regulation of body temperature is an example of negative feedback.
