Thyroid Hormones
|
- T3 an T4
- Regulate many physiological functions such as body temperature, metabolic rate, reproduction, and growth
|
|
Calcitonin
|
- Lowers blood calcium levels & blood phosphate levels by inhibiting release of the ions from bones and increasing the excretion by the kidneys
- Important in childhood (bone growth)
|
|
Parathyroid

|
|
Epinephrine
|
- a.k.a. adrenaline
- Secreted in response to low blood levels of glucose as well as exercise and stress
|
|
Norepinephrine hormone
|
- a.k.a. noradrenalin
- narrow blood vessels and raise blood pressure (increases heart rate)
|
|
Pancreas
|
- Converts the food we eat into fuel for the body's cells
- Glucagon, Insulin, and Somatostatin hormones (GIS)
