HOMEOSTASIS EXAMPLES

BODY TEMPERATURE as an example of HOMEOSTASIS � Cold air is blowing in the classroom and your body temperature drops quickly, the cold air is the stimulus � Receptors in the skin sense the decreased body temperature (these receptors are called thermoreceptors because they are temperature-sensitive) and they… � Send nerve impulses called input to the brain… � The brain acts as a control center which evaluates the input and sends… � Output in the form of nerve impulses to your skeletal muscles… � Your skeletal muscles are the effectors which cause you to shiver which generates heat as your muscles contract and… � Reverses the original stimulus and brings your body temperature back to normal to maintain HOMEOSTASIS!

BLOOD PRESSURE as an example of HOMEOSTASIS � Some stimulus disrupts homeostasis and your blood pressure changes (increases or decreases) � Receptors in the blood vessels sense the altered blood pressure (these receptors are called baroreceptors because they are pressure-sensitive) and they… � Send nerve impulses called input to the brain… � The brain acts as a control center which evaluates the input and sends… � Output in the form of nerve impulses to your heart and blood vessels… � Your heart and blood vessels are the effectors which cause a change in your heart rate and blood vessels which… � Reverses the original stimulus and brings your blood pressure back to normal to maintain HOMEOSTASIS!
