Presentation Transcript

  1. 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

  2. Nervous System Function: Controls thinkingand sends messages throughout body.

  3. Nervous System Structure: brain, spinal cord, nerves, and sensory organs.

  4. 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

  5. Integumentary System(SKIN) Function: Regulates body temperature, sensory response, rids body of waste and protection.

  6. Integumentary System(SKIN) Structure: Skin and sweat glands, Hair, Nails.

  7. 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/

  8. 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?

  9. Circulatory System Function: Transports materials around body

  10. Circulatory System Major Parts: • Heart • Blood vessels (veins, arteries, capillaries) • blood

  11. Circulatory System Homeostasis: S:Plaque begins to stick to artery walls, narrowing the vessel. R:Blood pressure increases.

  12. 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?

  13. Respiratory System Function: Supplies body with oxygen by breathing. Gets rid of carbon dioxide.

  14. Respiratory System Major Parts: • Nasal cavity • Trachea • Bronchi • Lungs • Alveoli • Diaphragm

  15. Respiratory System Homeostasis: S: A person visits a mountain so high that the air is very thin. R:A person must increase the breathing rate to sustain normal oxygen levels.

  16. 10/9 Warm-Up: grab the half sheet of paper from the front table by the human body model.

  17. Skeletal System Function: • Structure • Support • Protection • stores calcium • makes red blood cells • aids in movement

  18. Skeletal System Major Parts: • Bones • Joints • Cartilage • ligaments

  19. Skeletal System Homeostasis: S: A person is hit in the chest.. R: The person’s internal organs are not hurt. http://www.youtube.com/watch?v=J8x6tZI2hVI

  20. Muscular System Function: Gives body shape and aids in movement.

  21. Muscular System Major Parts: Muscles and tendons

  22. Muscular System Homeostasis: S: A football is thrown to a wide receiver.. R: The receiver raises his hands and catches the ball. https://www.youtube.com/watch?v=JMCPBuSjMfY

  23. Lymphatic System(Immune) Function: Helps body stay healthy by fighting off germs, diseases, & micro-organisms.

  24. Lymphatic System(Immune) Major Organs: • Lymph Nodes • Spleen • Tonsils

  25. Lymphatic System(Immune) Homeostasis: S: A germ is swallowed when a person eats with dirty hands. R: A person’s temperature increases and then vomits.

  26. Back of warm-up paper (Exit Paper) • ________ is to the cell as the nervous is to the body. • What is the main function of the circulatory system? • List the parts of the Integumentary system. • What is the main function of the respiratory system? • Of the systems we have gone over, which is your favorite? Why? • Which two systems provide oxygen to body cells?

  27. Digestive System Function: Break down food and absorb nutrients the body needs.

  28. Digestive System Major Organs: • Mouth • Esophagus • Stomach • Small intestine • Large intestine • Anus

  29. Digestive System Homeostasis: S: A person eats a candy bar. R:The intestines break down the candy bar and absorb nutrients.

  30. Urinary System Function: • Balance fluid levels • Rids the body of liquid waste • Filters the blood

  31. Urinary System Major Organs: • Kidney • Bladder • Ureters • Urethra

  32. Urinary System Homeostasis: S: A person’s body has elevated levels of fluid. R:A person’s bladder fills up.

  33. Excretory System Function: Rids the body of waste.

  34. Excretory System Major Organs: • Integumentary (sweat) • Digestive (poop) • Respiratory (exhale carbon dioxide) • Urinary (pee)

  35. Excretory System Homeostasis: S: A person’s body has a large amount of waste collecting in the large intestines. R: A person has to go to the restroom.

  36. Endocrine System Function: Secretes hormones Regulates body growth

  37. Endocrine System Structures: Glands (Adrenal flight or fight)

  38. Endocrine System Homeostasis: S: A person has just been confronted with a grizzly bear. R: A person secretes adrenaline to enact the fight or flight response. https://www.youtube.com/watch?v=gH8dGK7s6lY

  39. Reproductive System Function: reproduce / survive

  40. Reproductive System Structure: • Ovaries (eggs) and Vagina • Testes (sperm) and Penis

  41. Reproductive System Homeostasis: S: An egg has reached the uterus and has not been fertilized.. R: A female begins her period. https://www.youtube.com/watch?v=31b_70kzfwQ http://www.brainpop.com/health/bodysystems/reproductivesystem/
