Sheep

Adrenal glands receive signals through the autonomic nerves. Adrenal glands respond by pumping adrenaline into the bloodstream. Adrenaline causes the heart to beat faster, pushing blood to the muscles, heart, and other vital organs.

increasing blood flow to muscles allows for faster reaction and flight

Due to the bodies surge of released hormones, the heart beats faster and blood vessels narrow, increasing blood pressure. Small airways in the lungs open wide to take in more oxygen. Extra oxygen is sent to the brain to increase alertness. Sight, hearing, and other senses sharpen.

These hormones prepare the sheep to run away from the coyote

CNS receives fear signals from the amygdala in the sheeps brain

The hypothalamus activates the sympatheitc nervous system by sending signals through the autonomic nerves to the adrenal glands

Stimulates organs for fight or flight; Heart rate and breathing rate increase

Blood is directed to muscles, brain and heart in response to the threat

Kidneys regulates blood pressure by maintaining sodium homeostasis

Responsible for mainting homeostasis in the body during hight stress situations. Without this the kidneys would essentially go into overdrive and fail

nutrients are released into the bloodstream to supply the lamb with energy to run

Breathing rate increases in response to the threat in order to take in more oxygen

blood flows away from the heart and to the lungs so the sheep can run away faster
