Entering the Classroom

1. Please Entering the Classroom • Get out your packet that says: “Human Body Systems” and pick up an Exit Ticket Paper. • Get out your binder, a sharp pencil, and sit in your assigned seat. If you lost or forgot your packet, please take out a blank sheet of paper so you can copy the notes. Thank You!

2. Flashback (write answers in complete sentences) • When a radioactive element, like plutonium, decays, what happens? • A new element is formed • Energy turns into matter • Nutrients are given off • Carbon and Oxygen combine to produce Carbon Dioxide. Carbon dioxide is a compound because— • It has two chemicals • It is a molecule made of more than one atom • It is made of atoms of more than one element bonded together • Which of these reactions represents respiration (hint: we use respiration) • Water + oxygen  sugar + carbon dioxide • Sugar + oxygen  Carbon dioxide + water • Carbon dioxide + water  Sugar + Oxygen • Which of the above reactions represents photosynthesis?

4. Objectives • C: Describe how the skeletal and muscular system work together to move you. • L: Write Cue Words and a Summary of your notes Standard: II.I.III.1. Know that forces cause motion in living systems, including:• the principle of a lever and how it gives mechanical advantage to a muscular/skeletal system to lift objects• forces in specific systems in the human body (e.g., how the heart generates blood pressure, how muscles contract and expand to produce motion).

5. Key Question: How does your body work like a seesaw?http://www.youtube.com/watch?v=Ns2dkT2sIug

6. Skeletal System I. (p.310) The skeletal system is made up of bone and cartilage.

7. Skeletal System II. The skeletal system has several jobs • The major job is to support the body. • The skeletal system works together with the muscles to move the body. • The skeletal system protects important organs. • The skull protects the brain • Cartilage is tough, but flexible connective tissue. • Cartilage provides padding and protection at joints, but is not as hard as bone tissue http://www.youtube.com/watch?v=Ns2dkT2sIug

12. Exit Ticket (write in complete sentences) 5. Which body system is made of bones and cartilage?

13. Exit Ticket (write in complete sentences) 5. Which body system is made of bones and cartilage? The skeletal system is made of bones and cartilage.

14. Muscular System III. (p.316) Most muscles contract, or shorten, and pull on tendons, which pull on bones. This force on the bone makes your body move. • Muscles move bones only when muscles contract. • Most muscles work in teams of two (muscles work like levers). • Your biceps bend your elbow. • Your triceps straighten your arm.

18. Muscular System IV. (p.320) There are three types of muscle tissue in the human body. • Striated Muscles, like Skeletal Muscles are controlled by you. • Smooth Muscle is found in blood vessels, stomach, and other organs like the small intestine. • Cardiac Muscle is found only in the heart and major blood vessels. • Cardiac muscle contracts to make pressure in the blood vessels. • Blood pressure is the force of blood pushing on the arteries in the body.

23. Exit Ticket(answer in complete sentences) 6. What system moves your body? 7. When cardiac muscle shortens, it pushed blood into the arteries. What is “the force of blood pushing on the arteries in the body”? 8. When you lift something by bending your elbow, how does you bicep change? When you finish, write cue words and a summary for your notes.

24. Exit Ticket(answer in complete sentences) 6. What system moves your body? Your muscular system moves your body. 7. When cardiac muscle shortens, it pushed blood into the arteries. What is “the force of blood pushing on the arteries in the body”? That force is called “blood pressure.” 8. When you lift something by bending your elbow, how does you bicep change? Your bicep shortens (or contracts) when you lift.

25. Your assignment • Please write cue words and a summary for your notes. • If you finish early, start studying your Cornell Notes and vocabulary for our CBM (on Friday).
