1. 1/04/12 The Human Body
Objective: To learn the systems of the body, their functions, and how they are related
Bell work: Let’s see how much you know about your systems!
Then, a quick pre-assessment to see what you know about the 11 systems of the body!

2. What do you know?
You have 10 minutes to complete the Human Body Pre-Assessment on the front of your INB sheet by matching the body system with its function. If you finish before time is up, move on to the Medical Jargon sheet.
“Jar-WHAT?!?!?” Look at the sheet and try to infer what the word “jargon” means.
Using the terminology on the left, try to determine the meaning of the words on the right. Then match the term with its correct meaning.

3. 1/6/12 The Largest Organ: SKIN!
Objective: To learn the structure and function of the Integumentary System.
Bell Work: Put the terms in the correct order from most simple to most complex:
SKIN
OIL GLAND
INTEGUMENTARY SYSTEM
EPIDERMAL CELL

4. Made up of the skin, hair, and nails

5. Skin has four main functions
Protection - forms a protective covering over the body
Prevents infection and water loss

6. Help us sense our environment- touch Formation of Vitamin D
Regulation of body temperature
Blood vessels in skin help release/hold heat
Perspiration or sweating to keep cool and shivering to keep warm

8. Your skin is the largest organ of your body.
Skin is made up of three layers of tissue:
Epidermis - the outer, thinnest layer
Outermost cells are dead and rub off
New cells are constantly made at the base/bottom of the epidermis.
Cells produce melanin - pigment that protects your skin and gives it color

9. Dermis - the middle layer
Contains blood vessels, nerve fibers, muscles, oil, sweat glands, and other structures.
Fatty layer - covers and insulates the body

11. Skin Cross-section

12. 1/07/12 The Muscular System SKELETAL MUSCLE STRIATED MUSCLE CELL
Objective: To learn the structure and function of the muscular system
Bell Work: Put the terms in the correct order from most simple to most complex:
SKELETAL MUSCLE
STRIATED MUSCLE CELL
MUSCULAR SYSTEM
BICEP

13. Now, the Muscular System…
Muscle - an organ that can relax and contract, which moves your body.
Voluntary muscles - muscles you can control (bicep)
Involuntary muscles - muscles you cannot control (heart)

14. There are three types of muscle tissue Skeletal muscles move bones
Tendons connect muscle to bone
Voluntary
Contract quickly and tire more easily
Look striped or striated
Draw & Label the striated muscle in the circle on your paper

16. Draw & Label the smooth muscle in the circle on your paper
Smooth Muscles - found in digestive tract and blood vessels
Involuntary
Ex: Muscles in the stomach
Draw & Label the smooth muscle in the circle on your paper

18. Draw and Label the cardiac muscle in the circle on your paper
a. Found only in the heart
b. Is striated (striped)
c. Involuntary
Draw and Label the cardiac muscle in the circle on your paper

20. You move because pairs of muscles work together
When one muscle of a pair contracts, the other relaxes
Muscles always pull
Blood carries energy-rich nutrients to the muscles so they can do their work.

21. 1/08/12 Dem Crazy Bones!
Objective: To learn the function and structure of the skeletal system.
Bell Work: Put the terms in the correct order from most simple to most complex (use your root words for the ones you don’t know!)
MARROW
SKULL
SKELETAL SYSTEM
OSTEOCYTE

22. Bones of the Skeleton (left side)
Cranium (skull)
Frontal (forehead)
Mandible (jaw)
Cervical Vertebrae (neck - 6)
Thoracic Vertebrae (vertebrae with ribs – 12)
Xiphoid Process
Lumbar Vertebrae (lower back – 5)
Illium (hipbone)
Sacrum
Coccyx (tailbone)
11. Ischium (buttbone)
12. True ribs (directly attached to sternum)
13. False ribs (attached to sternum by cartilage)
14. Floating ribs (not attached at all)
15. Intercostal cartilage
Bones of the Skeleton (left side)

23. Bones of the Skeleton (right side)
16. Nasal bone
17. Ocular Orbit (eye socket)
18. Maxilla (upper jaw)
Clavicle (collar bone)
Scapula (shoulder blade)
Sternum (breast bone)
Humerus (upper arm)
Radius (closest to the thumb)
Ulna (furthest from thumb) “Ulna you didn’t!”
Carpals (wrist bones)
Metacarpals (palm of hand)
Phalanges (fingers)
Femur (thigh bone)
Patella (knee cap)
Tibia (shin bone)
Fibula (I told a “little fib”ula)
Calcaneous (heel bone)
Tarsals (ankle bones)
Metatarsals (sole of foot)
Phalanges (toes)
Bones of the Skeleton (right side)

24. The Skeletal System
All the bones in your body make up your skeletal system - has five major functions
Shapes and supports body
Protects organs
Movement
Blood cells are made in bone marrow
Stores calcium and phosphorus

25. Bone Structure
Periostium - soft thin substance that covers and protects the bone
Compact bone – tough, hard bone that can heal itself when broken
Spongy bone – contains red marrow which makes red blood cells that carry oxygen and carbon dioxide throughout the day
Marrow – soft, inner center of bones containing blood vessels and fat cells. Manufactures blood cells

28. Your skeleton begins as cartilage, which is gradually broken down and replaced with bone which is why babies have more bones (300) than adults (which have 206).

29. Introduction to Joints
Joint - any place where two or more bones come together
Cartilage - rubbery tissue that cushions bones , located at joints
Ligament – attaches bone to bone

30. Allows little movement ex: joints of the bones in your skull
Types of Joints
Fixed joint
Allows little movement
ex: joints of the bones in your skull
Pivot Joint
One bone rotates around another bone
ex: turning your head

31. Ball-and-socket joint
The ball end of one bone fits into a cuplike cavity on another bone.
ex: Shoulder joint
4. Hinge joint
Back and forth
ex: knee

32. Sliding joint
One part of a bone slides over another bone.
ex: Hand bone (bones in your palm)
