The Endocrine System

What is the Endocrine System? Definition: a system of the body which consists of glands that release substances (hormones) into the bloodstream Hormones: affect behavior and emotions stimulate growth & reactions circulate throughout the whole body are produced in glands

What are the Types of Glands? (Gonads)

The Types of Glands Pituitary Gland: called the “master gland” because it motivates other glands into action

The Types of Glands Adrenal Gland: regulates the body during states of alarm Produce adrenaline (intensify emotions) Produce noradrenaline (raise blood pressure) Help arouse body & enable body to cope w/stressful situation

The Types of Glands Thyroid Gland: regulates the metabolic (converting food to energy) rate of the body by produce thyroxin Too little Thyroxin produces stunted growth & overweight Too much Thyroxin produces excitability, can’t sleep, weight loss

The Types of Glands Pancreas: regulates sugar metabolism Produces the hormones  insulin, glucagon, & somatostatin

The Types of Glands Gonads: regulates sexual characteristics and reproduction Produce Testosterone (male sex hormone) Produce Estrogen (female sex hormones) Produce Progesterone (female sex hormones)
