  1. AIM: How do the different systems of the body function to keep you alive? 4/15/13 DO NOW: • Pick up your quiz & finish it. HOMEWORK: ILS LE REVIEW BOOK • Read p. 1-6 • Answer Questions #51-100 on p. 15-22 SCAN-TRONS DUE – 8AM Tomorrow

  2. How are multicellular organisms organized? CellsTissueOrganSystemsOrganism

  3. What is the function of the digestive system • Prepares food (nutrients) for absorption into the blood • How are the two types of digestion different? • Mechanical digestion (chewing) • Chemical digestion (enzymes)

  4. What is the function of the Respiratory System? • Takes in oxygen to make energy • Removes carbon dioxide • Where does oxygen & carbon dioxide exchange tale place? • Alveoli is the site of gas exchange in the lungs Alveoli

  5. What is the function of the Circulatory System? • Transports materials throughout the body. • What are the components of blood? • Red Blood cells – carry oxygen & CO2 • White Blood cells – Fight infections • Platelets – Clot blood (stop bleeding) • Which organ pumps the blood? • Heart – pumps the blood

  6. Name the 3 types of blood vessels? • Arteries, Veins, Capillaries Which blood vessels carry blood away from the heart? Toward the heart? • Arteries – carries blood Away from heart • Veins – carries blood to the heart In which blood vessels does gas and nutrient exchange take place? • Capillaries – smallest – gas & nutrient exchange takes place with the cell

  7. What is the function of the Immune System? • To help protect the body against microorganisms • What are the parts of the immune system? • Skin, mucous, acid, white blood cells, antibodies • What is a vaccine and why are they important? • Vaccinations- weak virus, helps your body produce antibodies • How does an infectious disease differ from a non-infectious disease? • Infectious Disease • Contagious, can catch • Caused by a microorganism • Non infectious Disease • Cannot catch

  8. What is the function of the Excretory System? • To remove waste from the body • Identify the organs of the Excretory System? • Kidneys- urine • Lungs-carbon dioxide • Skin- perspire water & salts • Liver- removes chemicals & toxins

  9. What is the function of the Nervous System? • Controls your body • Helps your body respond to a stimulus • Identify the organs of the Nervous System. • Brain • Spinal cord • Neurons • Describe the speed of the electrical nerve impulses? • Electrical impulses travel at lightning quick speeds through your neurons.

  10. What is the function of the Endocrine System? • Controls responses to internal and external stimuli. • How does the endocrine system control responses • Hormones • Identify the organs of the endocrine.

  11. What is the function of the Muscular & Skeletal Systems? • Structure • Support • Locomotion (movement) • Identify the structures that make up the Muscular & Skeletal System. • Muscles • Bones

  12. What is the function of the reproductive systems? • Produces sex cells necessary for the production of offspring. Identify the male and female organs of the reproductive system? • Male- Testes • Female- Ovaries What are the male and female sex cells? • Male – Sperm • Female – Eggs

  13. Summary Questions: • How does mechanical digestion differ from chemical digestion? • How do Arteries differ from veins • Explain how the respiratory and circulatory systems work together to keep us alive. • How does our immune system protect us? • How does our excretory system remove wastes? • How do 8 of the systems of our body function to help us run away from a dog chasing us?
