The document outlines the 11 major organ systems of the human body, describing their functions and main components. The systems are: 1) integumentary, which covers and protects the body; 2) skeletal, which provides structure and support; 3) muscular, which produces movement; 4) nervous, which senses stimuli and coordinates activities; 5) endocrine, which regulates metabolism via hormones; 6) cardiovascular, which transports blood; 7) lymphatic, which defends against disease; 8) digestive, which breaks down food; 9) respiratory, which exchanges gases; 10) urinary, which removes waste; and 11) reproductive, which creates offspring. The document concludes by assigning students lab groups to create skits about

1. Organ Systems (pg 6)

2. 1. Integumentary System
• Functions: Covers and protects the body,
regulates temperature
• Components: Skin, hair, nails, sweat and oil
glands

3. 2. Skeletal System
• Functions: Provides support for body,
attachment point for muscles
• Components: Bones, cartilage, ligaments

4. 3. Muscular System
• Functions: Produces movement, maintains
posture, produces heat
• Components: Muscles, tendons

5. 4. Nervous System
• Functions: Senses and responds to stimuli,
coordinates body activities
• Components: Brain, spinal cord, nerves, sense
receptors

6. 5. Endocrine system
• Functions: Produces hormones, which
regulate metabolism and body chemistry
• Components: Pituitary, pineal, adrenal,
thyroid, thymus, pancreas, gonads

7. 6. Cardiovascular
• Functions: Transports oxygen and nutrients to
body tissues
• Components: Heart, blood vessels, blood

8. 7. Lymphatic
• Functions: Defends against disease, returns
fluid to blood
• Components: Lymph vessels, lymph nodes,
spleen

9. 8. Digestive
• Functions: Digests food and absorbs nutrients
• Components: Mouth, esophagus, stomach,
intestines, liver, gallbladder, pancreas

10. 9. Respiratory
• Functions: exchanges gases between air and
blood
• Components: Trachea, lungs

11. 10. Urinary
• Functions: Excretes wastes
• Components: Kidneys, urinary bladder

12. 11. Reproductive
• Functions: Creates new humans
• Components: Testes, ovaries, and accessory
structures

13. Organ Skits!
• You will work in your lab groups to create a
short (1-2 minutes) skit about the location and
functions of an organ
• Use your book to help you
• Write the script on page 7 (every member
must write down the whole script)

14. Choose one of the following organs:
Kidneys
Liver
Pancreas
Lymph nodes
Gallbladder
Trachea and esophagus
Thyroid and thymus
Spleen
