1. Warm-Up #2
There are 11 Human Body organ systems that we will be studying this year. But before we begin learning about any of them, I want you to tell me which systems you are already aware of. As your warm- up, please write as many of the 11 organ systems that you know AND one organ that may be involved with that system…

2. Body Systems Review
Physiology

3. “All systems are both independent & interconnected”
Here they are…
Circulatory (heart, arteries, veins)
Urinary or excretory (urethra, urinary bladder, kidney)
Immune or lymphatic (lymph vessels, lymph nodes, spleen)
Muscular (skeletal muscles)
Digestive (stomach, intestine)
Nervous (spinal chord, brain, nerves)
Integumentary (skin, hair)
Reproductive (uterus, ovaries, testis)
Skeletal (cartilage, bones, joints)
Respiratory (lungs, diaphragm)
Endocrine (thyroid gland, pineal gland)

4. A Mnemonic? What is a Mnemonic (ne-mon-ic)? MURDER IN CSI
A random short phrase that is used to help remember lists or facts
Ex: ROY G. BIV - tells the colors of a rainbow in their order (red, orange, yellow, green, blue, indigo, and violet)
Ex: SOHCAHTOA - helps to remember sin, cos, and tangent in geometry
MURDER IN CSI
Muscular, urinary, respiratory, digestive, endocrine, reproductive, immune (lymphatic), nervous, circulatory, skeletal, integumentary (skin)

5. Nervous Nervous System
Structures: Brain, spinal cord, peripheral nerves
Function: Recognizes and coordinates the body’s response to changes in its internal and external environments

6. Integumentary Integumentary System
Structures: Skin, hair, nails, sweat and oil glands
Function: Serves as a barrier against infection and injury; helps to regulate body temperature; provides protection against ultraviolet radiation from the sun

7. Skeletal Skeletal System
Structures: Bones, cartilage, ligaments, tendons
Function: Supports the body; protects internal organs; allows movement; stores mineral reserves; provides a site for blood cell formation

8. Muscular Muscular System
Structures: Skeletal muscle, smooth muscle, cardiac muscle
Function: Works with skeletal system to produce voluntary movement; helps to circulate blood and move food through the digestive system

9. Circulatory Cardiovascular System
Structures: Heart, blood vessels, blood
Function: Brings oxygen, nutrients, and hormones to cells; fights infection; removes cell wastes; helps to regulate body temperature

10. Respiratory Respiratory System
Structures: Nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs
Function: Provides oxygen needed for cellular respiration and removes excess carbon dioxide from the body

11. Digestive Digestive System
Structures: Mouth, pharynx, esophagus, stomach, small and large intestines, rectum
Function: Converts food into simpler molecules that can be used by the cells of the body; absorbs food; eliminates wastes

12. Urinary Excretory System
Structures: kidneys, ureters, urinary bladder, urethra
Function: Eliminates waste products from the body in ways that maintain homeostasis

13. Endocrine Endocrine System
Structures: Hypothalamus, pituitary, thyroid, parathyroid, adrenals, pancreas, ovaries (in females), testes (in males)
Function: Controls growth, development and metabolism through hormones, maintains homeostasis

14. Reproductive Reproductive System
Structures: Testes, epididymis, vas deferens, urethra, and penis (in males), ovaries, Fallopian tubes, uterus, vagina (in females)
Function: Produces reproductive cells; in females, nurtures and protects developing embryo

15. Lymphatic Immune System
Structures: White blood cells, thymus, spleen, lymph nodes, lymph vessels
Function: Helps protect the body from disease; collects fluid lost from blood vessels and returns the fluid to the circulatory system
