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
![Page 12: Aim: to describe the structures and functions of the endocrine system](https://reader036.fdocuments.in/reader036/viewer/2022062410/568164ce550346895dd6f48a/html5/thumbnails/12.jpg)
HypothalamusThe hypothalamus makes hormones that control the pituitary gland. In addition, it makes hormones that are stored in the pituitary gland.
Pituitary glandThe pituitary gland produces hormones that regulate many of the other endocrine glands.
Parathyroid glandsThese four glands release parathyroid hormone, which regulate the level of calcium in the blood.
ThymusDuring childhood, the thymus releases thymosin, which stimulates Tcell development.
Adrenal glandsThe adrenal glands release epinephrine and nonepinephrine, which help the body deal with stress.
Pineal glandThe pineal gland releases melatonin, which is involved in rhythmic activities, such as daily sleep-wake cycles.
ThyroidThe thyroid produces thyroxine, which regulates metabolism.
PancreasThe pancreas produces insulin and glucagon, which regulate the level of glucose in the blood.
OvaryThe 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.
Testis The testes produce testosterone, which is responsible for sperm production and the development of male secondary sex characteristics

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
![Page 19: Aim: to describe the structures and functions of the endocrine system](https://reader036.fdocuments.in/reader036/viewer/2022062410/568164ce550346895dd6f48a/html5/thumbnails/19.jpg)
PancreasFeedback Loop1. After a meal blood
sugar levels are high2. Triggers release of
insulin3. Formation of glycogen
molecules4. Stored in liver thereby
lowering glucose in blood
5. Before a meal blood sugar levels are low
6. Triggers release of glucagon
7. Glycogen molecules are broken down into glucose molecules

Before mealsGlucose
levels are low in the
blood
Pancreas secretes
glucagon
Liver changes glycogen to glucose
Glucose sent to target tissues
Target tissues need
glucose
![Page 22: Aim: to describe the structures and functions of the endocrine system](https://reader036.fdocuments.in/reader036/viewer/2022062410/568164ce550346895dd6f48a/html5/thumbnails/22.jpg)
After a mealGlucose
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

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