Mr. Brown recently purchased a flock of Cheviot sheep to graze the back meadows of his property. The sheep are a little flighty, but as long as he remains calm and deliberate, they handle fairly well. This morning, he went out to check on them. He found they were huddled tightly and as he approached, they ran to the far corner of the pasture. Standing in the corner panting, the sheep looked as if they had never seen a person before. While he was wondering what stirred the animals, he heard a coyote cry out close by.

Renal System
The renal system creates the hormones present in the adrenal gland that regulates the sheep's fight or flight response. This plays a role in the sheep's reaction and causes them to be more flighty even after the coyote left.

Endocrine System
The endocrine system is responsible for hormones in the body. It includes two hormone producing glands called the adrenal, and the pituitary gland.
Adrenal
-The adrenal gland produces epinephrine and nor epinephrine
-It controls fight or flight response
Pituitary
-This is the main or master gland
-It secrets hormones to control the other endocrine glands
When the sheep saw the coyote their fight or flight response was being controlled by the adrenal gland. The gland also likely caused a raise in the sheep's blood pressure in response to the sheep's stress and fear. The hormones produced by this system played a role in the sheep's response to the coyote.
