Humans Have Systems Humans Have Systems For:For:
Movement/Support/ProtectionDigestionCirculationRespirationExcretion (Waste Removal)Control and CoordinationReproductionProtection from disease
These systems These systems interactinteract to to keep an organism keep an organism
working properly and help working properly and help maintain maintain homeostasishomeostasis
MovementMovement
The The skeletal systemskeletal system and and muscular systemmuscular system work together so humans can work together so humans can movemove
Why is movement important? Why is movement important? escaping dangerescaping dangerobtaining food and shelterobtaining food and shelterreproductionreproduction
The Skeletal System The Skeletal System Also…Also…
Provides Provides protectionprotection for for the the internal organsinternal organs
And…And…
Inside of the boneInside of the bone is is bone marrow which is bone marrow which is where where blood cells are blood cells are producedproduced
More About Muscles…More About Muscles…
There are There are different typesdifferent types of muscles of muscles
Skeletal muscle is voluntarySkeletal muscle is voluntary (under conscious (under conscious control) and control) and movesmoves the bones the bones
Smooth muscle is involuntarySmooth muscle is involuntary (under (under unconscious control) and is found in places unconscious control) and is found in places like the like the digestive tractdigestive tract and and lines blood vesselslines blood vessels
Cardiac muscle is involuntaryCardiac muscle is involuntary and is found in and is found in the the heartheart

Circulatory SystemCirculatory System
Moves substancesMoves substances to and from cells to and from cells
This system is necessary to This system is necessary to supply needed supply needed materials to the cells and remove cell materials to the cells and remove cell products and wastesproducts and wastes
Respiratory SystemRespiratory System
For For gas exchangegas exchange
Supplies oxygenSupplies oxygen to the body and to the body and removes removes carbon dioxidecarbon dioxide
This system is necessary so that This system is necessary so that cells can cells can use the oxygen to release the energyuse the oxygen to release the energy stored
Excretory SystemExcretory System
Gets Gets rid of all body wasterid of all body waste products products
Removes excess heatRemoves excess heat energy energy
This system is necessary because of the This system is necessary because of the build up of waste products and poisons in build up of waste products and poisons in the cellsthe cells
Don’t forget, these are also Don’t forget, these are also part of the excretory part of the excretory

Control and coordinationControl and coordination
The The nervous and endocrine systemsnervous and endocrine systems interact interact to control and coordinate the body’s to control and coordinate the body’s responseresponse to internal and external changes to internal and external changes
The The response to stimuliresponse to stimuli
The Nervous SystemThe Nervous SystemThe The central nervous central nervous
system (CNS) is your system (CNS) is your brainbrain (central control) (central control) and spinal cordand spinal cord (links (links the brain to other parts the brain to other parts of the body)of the body)
Other Other nerves provide nerves provide the pathwaysthe pathways to to muscles, glands and muscles, glands and sense organssense organs
The Endocrine SystemThe Endocrine System
• Regulates growth Regulates growth development and development and reproductionreproduction through through glandsglands
• Glands produce Glands produce hormoneshormones – chemical – chemical messengersmessengers that affect that affect other parts of the bodyother parts of the body
