Explain the effect of pituitary extract on urine output.
The ears of a rabbit play an important part in
helping the animal to keep its body temperature
constant.
After a period of exercise, the insides of a rabbit’s
ears become redder in colour as the blood flow to
the skin surface increases.
Explain how the different components of nervous
communication are involved in the process leading
to the response shown by the rabbit’s ears.
