Y10 - Homeostasis and thermal regulation

Front

What is homeostasis?

Back

Homeostasis is the regulation of internal conditions to maintain optimal function in an organism.

Front

True or False: Homeostasis responds to internal and external changes.

Back

TRUE

Front

Which part of the brain is involved in negative feedback?

Back

The hypothalamus.

Front

What is the role of coordinators in homeostasis?

Back

Coordinators process the information and coordinate the response.

Front

What do temperature receptors in the skin send to the thermoregulatory centre?

Back

Nervous impulses.

Front

Define negative feedback in the context of homeostasis.

Back

Negative feedback is a process that counteracts a change in a controlled condition, helping to maintain homeostasis.

Front

What is the function of effectors in homeostasis?

Back

Effectors bring about the response to restore balance in the body.

Front

Give an example of a condition regulated by homeostasis.

Back

Body temperature is an example of a condition regulated by homeostasis.

Front

What happens when body temperature rises above normal?

Back

The hypothalamus triggers mechanisms such as sweating to cool the body down.

Front

What is the significance of the thermoregulatory centre?

Back

The thermoregulatory centre in the hypothalamus regulates body temperature by processing information from temperature receptors.
