The nervous system and the endocrine system both coordinate responses in the human body.
Give two ways in which a response coordinated by a hormone is different from a response coordinated by the nervous system.
A person is startled by a loud noise. Their heart rate rises within one second of hearing the noise. Their heart rate is still high three minutes after the noise has stopped.
Explain which of these two effects is caused by the nervous system and which is caused by a hormone.
