How many systems are in the Human Body?
BODY SYSTEMS 1. Skeletal System bones • provides internal support • protects vital tissues and organs • allows for muscle attachment • production of blood cells
BODY SYSTEMS 2. Muscular System muscles • contract together (rarely alone) • move the bones they are anchored to • produce body heat
BODY SYSTEMS 3. Nervous System neurons • the brain, spinal cord, and networks of nerves receive messages from in and outside body • nerves transmit instructions for all body activities, learning and memory
BODY SYSTEMS 4. Endocrine System endocrine glands • produces hormones (chemical messengers) • hormones secrete into blood and are carried to every cell in body • hormones regulate the activity of specific tissues and organs
BODY SYSTEMS 5. Circulatory System heart, blood and vessels • delivers oxygen and nutrients to all cells • removes waste from cells via blood
BODY SYSTEMS 6. Respiratory System lungs • Allows for breathing to occur • exchange of gases between the inside and outside of the body • movement of gas molecules to and from the blood
BODY SYSTEMS 7. Integumentary System skin, hair and nails • • protects internal body provides external support contains sensory receptors assists in regulating body temperature
BODY SYSTEMS 8. Lymphatic and Immune Systems lymph glands and vessels, spleen, tonsils, thymus gland etc. • restores excess interstitial fluid and proteins to the blood via the subclavian veins • absorbs fats and fat-soluble vitamins from the digestive system • defends against invading organisms (eg. bacteria, viruses) by storing white blood cells in lymph nodes, spleen etc. (immune system)
BODY SYSTEMS 9. Digestive System long passageway called the alimentary canal (digestive tract) • breaks down food materials • absorbs food materials • excretes waste materials
BODY SYSTEMS 10. Urinary System 2 kidneys, 2 ureters, a bladder and a urethra • maintains balance of chemicals in body • removes waste products from blood as urine
BODY SYSTEMS 11. Reproductive System Female: • organs are situated inside body • function to ripen and release egg at regular intervals • provide protection and nourishment for fertilized egg (embryo) and fetus
BODY SYSTEMS 11. Reproductive System Male: • organs situated inside and outside of body • function to continuously produce sex cells (gametes) called sperm, reducing with age
TASK: 1. Your group will be given 5 particular scenarios 2. Work together to try to: i) Identify the systems involved in the scenario ii) Describe the connections between the body systems *HINT* Consider how the body systems work together!
