Engage You will be viewing some video clips from Sideshow: Alive On The Inside. Within these clips you will see various types of endocrine disorders. Write down observations and questions you have about the endocrine system. If you are interested in viewing more endocrine system oddities, you can read the book Freak Show: Presenting Human Oddities for Amusement and Profit by Robert Bogdan.

Endocrine System Functions •Regulates many bodily functions •Maintains homeostasis by regulating the production of chemicals that affect most functions of the body •Secretes substances that aid the nervous system •Important regulator of growth and development •Endocrine glands are ductless glands, unlike exocrine glands that secrete substances into ducts.

Endocrine System Structures Glands – release products to bloodstream directly. Horomones – products deliver messages to body Target cells – have specific receptors for specific hormones

Endocrine Glands Section 39-1 Hypothalamus Pineal gland The hypothalamus makes hormones that control the pituitary gland. In addition, it makes hormones that are stored in the pituitary gland. Pineal gland The pineal gland releases melatonin, which is involved in rhythmic activities, such as daily sleep-wake cycles. Thyroid The thyroid produces thyroxine, which regulates metabolism. Pituitary gland The pituitary gland produces hormones that regulate many of the other endocrine glands. Pancreas The pancreas produces insulin and glucagon, which regulate the level of glucose in the blood. Parathyroid glands These four glands release parathyroid hormone, which regulate the level of calcium in the blood. Ovary The ovaries produce estrogen and progesterone. Estrogen is required for the development of secondary sex characteristics and for the development of eggs. Progesterone prepares the uterus for a fertilized egg. Thymus During childhood, the thymus releases thymosin, which stimulates Tcell development. Testis The testes produce testosterone, which is responsible for sperm production and the development of male secondary sex characteristics Adrenal glands The adrenal glands release epinephrine and nonepinephrine, which help the body deal with stress.

Hypothalamus Controls pituitary secretions Links nervous system to endocrine

Pituitary Glands Controls the other endocrine glands aka Master Gland Hormone Functions Growth Hormone (GH) Regulates growth of organism Antidiuretic (ADH) Stimulates kidneys to keep water

Thyroid Glands Regulates metabolism and energy balance Hormone Function Thyroxine Regulates body energy usage Calcitonin Regulates calcium and phosphate in blood

Parathyroid Glands Regulates calcium levels Hormone Function Parathyroid Hormones (PTH) Increases calcium, phosphate and magnesium absorption in intestines Causes bones to release calcium and phosphate

Adrenal Glands Releases hormones to deal with stress Secretes adrenaline Hormone Function Corticosteriods Controls blood pressure and blood sugar levels Epinephrine/ norepinephrine Triggers fight or flight response

Pancreas Glands Regulates blood sugar levels Secretes insulin Hormone Function Insulin Lowers blood sugar by packaging glucose molecules in glycogen to be stored in the liver Glucagon Raises blood sugar by breaking down glycogen in glucose

Pancreas Feedback Loop After a meal blood sugar levels are high Triggers release of insulin Formation of glycogen molecules Stored in liver thereby lowering glucose in blood Before a meal blood sugar levels are low Triggers release of glucagon Glycogen molecules are broken down into glucose molecules

Thymus Glands Secretes Thymosine Part of the immune system Hormone Function Thymosine T-cell development

Before meals Glucose levels are low in the blood Pancreas secretes glucagon Liver changes glycogen to glucose Glucose sent to target tissues Target tissues need glucose

After a meal Glucose levels are high in the blood Pancreas secretes insulin Glucose goes to the liver and glycogen is produced Glycogen sent to target tissues Target tissues don’t need glucose

Diabetes Diabetes High sugar levels in blood Do not produce enough insulin to control blood sugar Some take insulin injections to regulate

Reproductive Glands Production of gametes Secretion of sex hormones (sex cell) Female Ovaries Estrogen Ovum Male Testes Testosterone Sperm

When Things Go Wrong With the Endocrine System! Directions: Read and summarize using the Rule-base strategy. Write a paragraph explaining which endocrine system disorder you would find easiest to live with. Just a paragraph! So dig deep and delete! Remember to use A.C.E. I.T!

Explain List 4 types of endocrine glands and give their function. What is the overall function of the endocrine system? With what other systems does the endocrine system interact?

Student Council Notify school about student council. How? When? Where?

Nominating Candidates Homework Come in with a list of students that you think would be good candidates for student government.

Parathyroid Glands Calcium Regulation PTH-Parathyroid hormones Increases calcium, phosphate, and magnesium absorption in intestines. Causes bones to release calcium and phosphate Causes removal of calcium and magnesium from urine by kidneys Increases the making of Vitamin D in body

Negative Feedback Mechanism Our body uses feedback mechanism to maintain homeostasis within our body. Regulation of calcium is one example of this process. Can you think of another one? Hint: Role Play Activity

Questions PTH cause the small intestine to absorb more calcium, _____ and _____. What does PTH cause the bones to release? What do the kidneys do because of PTH?

Questions What organ regulates glucose in blood? When we eat our blood glucose level is high or low? In between meals our blood glucose level is high or low? When our blood glucose is high the pancreas secretes ___________. When our blood glucose is low the pancreas secretes ___________. What mechanism allows our body to control the glucose level in our body?
