The Endocrine System

2/11/14 Sit in your assigned seats. DO NOT TOUCH THE BOARDS OR THE BOXES. Warm up Which part of the brain is the largest? What 4 parts is this part of the brain divided into?

Body Systems so far. Integumentary System- Protection Muscular System- Movement Skeletal System- Structure and movement Digestive System- Breaking down food into nutrients that can easily be absorbed Circulatory System- Distributes blood throughout the body Respiratory System- Puts Oxygen in the blood Excretory System- Gets rid of wastes Nervous System- Controls bodily functions through electrical impulses Endocrine System- ?

1.What is the function of the Endocrine System? Produce and secrete hormones that regulate growth, metabolism, and sexual development/function

3. What is a Hormone? Definition: Targeted chemical messengers that regulate cells or organs Hormones transfer information and instructions from one set of cells to another. Many different hormones move through the bloodstream, but each type of hormone is designed to affect only certain cells. Hormones are transported by the CIRCULATORY system

2. What is a gland? Glands are the organs of the endocrine system that produces and secretes, or gives off, chemicals called hormones. They hold the hormones until the brain tells them to release the hormones into the blood stream.

4. Hypothalamus Releases hormones which stimulate the pituitary gland.

5. Pituitary Gland Stimulated by hormones from the hypothalamus. Regulates several physiological processes (including stress, growth, reproduction, and lactation)

6. Thyroid Gland Thyroid: control the rate at which cells burn fuels from food to produce energy. (metabolism)

7. Adrenal Gland Adrenal: Releases hormones in response to stress. It also increases blood pressure and heart rate when the body experiences stress. Produces adrenaline fight or flight response.

8. Pineal Gland Pineal: It secretes melatonin a hormone that may help regulate when you sleep at night and when you wake in the morning.

9. Testes Testes (male): produce sex hormone testosterone.

10. Ovaries Ovaries (female): produce sex hormone estrogen.

11. Pancreas Pancreas: produces two important hormones, insulin and glucagon. They work together to maintain a steady level of glucose, or sugar, in the blood and to keep the body supplied with fuel to produce and maintain stores of energy.

12. Problems that can occur in the Endocrine System Overactive glands: overgrowth, early puberty Underactive glands: weight gain, late puberty, undergrowth Diabetes
