3. 11 Systems in the Human Body...
Lymph
All Working Together...

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

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

6. All Working Together...
The digestive system does not work without the help of other organ systems.
The digestive system needs the cardiovascular system to deliver the nutrients to other organs in the body such as the muscles and the brain.

7. Circulatory System Structure: Heart, blood vessels, and blood
Function: Brings oxygen, nutrients, and hormones to cells; fights infections; and regulates body temperature

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

9. All Working Together...
The circulatory system depends on the pulmonary system (lungs) to deliver oxygen to muscles and other organs.

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

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

12. All Working Together...
Muscles and bones work together to produce movement.

13. Excretory System
Structures: Skin, lungs, kidneys, ureters, urinary bladder, and urethra
Function: Eliminates waste products of metabolism from the body and maintains homeostasis

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

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

16. All Working Together... Lymph
Getting rid of waste is another necessary function of the body:
Lungs get rid of carbon dioxide.
Lymphatic vessels recycle extra fluids that build-up next to cells and tissues.
Kidneys filter the blood of toxins.
Skin releases excess salts through sweat.
Lymph

17. Endocrine System
Structures: Hypothalamus, pituitary gland, thyroid, parathyroid, adrenals, pancreas, ovaries (female), and testes (male)
Function: Controls growth, development, metabolism and reproduction

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

19. All Working Together...
Reproduction, growth and development are critical functions of all living things.
The endocrine system provides the chemical messages for growth, development, and proper functioning of the reproductive system.
