Body Systems How is your body like a machine?
Lets think back…. Why do all the body systems work together?
To maintain homeostasis!
Four major themes 1. feedback loops 2. structure and function 3. division of labor 4. interdependence of organ systems
SKELETAL SYSTEM What are the functions? - produces red and white blood cells -movement What other systems are involved? -structural support -provide minerals - muscular -immune circulatory
MUSCULAR SYSTEM What other systems does it involve? What are the functions? -movement (body parts, digestion, circulation) -Skeletal -Digestive -Circulatory -Nervous
Muscle Types SKELETALSMOOTHCARDIAC
How do you bend your elbow? The bicep muscle contracts, causing the elbow to bend. The tricep muscle contracts, causing the elbow to straighten. This works similar to what simple machine? To what are muscles attached?
LYMPHATIC SYSTEM Helps protect the body from disease Collects fluid lost from blood vessels and returns the fluid to the circulatory system
LYMPHATIC SYSTEM What are the functions? protect body from disease contains white blood cells, antibodies and lymph
INTEGUMENTARY SYSTEM FunctionSystem Protection/Barrier Immune Protect Against Dehydration Excretory Cutaneous SensationNervous Regulate Body TempExcretory Excrete Sweat, Gases Excretory
