10/7 Warm-up • Turn to a new page and copy the definitions below. • Homeostasis: process of maintaining balance (equilibrium) inside the body. • Stimuli – something that causes a response • Response – effect of stimuli
Nervous System Function: Controls thinkingand sends messages throughout body.
Nervous System Structure: brain, spinal cord, nerves, and sensory organs.
Nervous System Homeostasis: • S: A person touches a hot stove. • R: A person’s body sends a message to move their hand. http://www.youtube.com/watch?v=x4PPZCLnVkA http://www.youtube.com/watch?v=aboVLnsCH44
Integumentary System(SKIN) Function: Regulates body temperature, sensory response, rids body of waste and protection.
Integumentary System(SKIN) Structure: Skin and sweat glands, Hair, Nails.
Integumentary System(SKIN) S: A person walks outside while it is snowing wearing shorts. R: A person get chill bumps and begins to shiver. http://www.brainpop.com/health/bodysystems/skin/
10/8 WarmUp • If George made a model of the human eye, what system would he be making a model for? • The _______is to the cell; like Integumentary system is to the body. • What is an example of something that keeps homeostasis in your house?

Circulatory System Major Parts: • Heart • Blood vessels (veins, arteries, capillaries) • blood
Circulatory System Homeostasis: S:Plaque begins to stick to artery walls, narrowing the vessel. R:Blood pressure increases.
What does the pipette, the water, and balloon represent in this model of the circulatory system? • The action of applying pressure to and releasing pressure from the pipette demonstrates what function of the circulatory system? • What is a limitation of using this model as opposed to the human body? • If you placed a bean in the balloon, what would the bean represent? • What would happen if you squeezed water through the pipette leaving the bean in the balloon, how would the experiment be different?
