Name: Key Class period: Quiz 1 Review Sheet : (Body organization, Skeletal, Muscular, and Integumentary Systems) 1. What is homeostasis? -maintenance of a stable, internal environment 2. What is an example of homeostasis? -regulation of body temp (sweating/ shivering), water level (thirst/ urination), nutrients (hunger/ elimination), blood sugar, respiration (levels of O2 and CO2), etc 3. Put the following words in order from smallest to largest: organ, cell, organ system, tissue. Cell, tissue, organ, organ system 4. What are the 4 types of tissue found in the body? 1. muscle 2. nervous 3. connective 4. epithelial 5. What are the 3 parts of the skeletal system? 1. bones 2. joints 3. Connective tissue (cartilage, ligaments) 6. What are the 4 functions/ jobs of bones? ___protect internal organs___ ___make blood cells___ __movement___ __stores minerals____ ***also could include: provides frame, structure/ support 7. Describe the movement for each joint type listed and say where each can be found in the body. Ball and socket- moves in a circle (shoulder/ hip) Hinge- opens/ closes (knee, elbow) Pivot- twists (neck/ elbow) Immovable- Doesn’t move/ fixed (skull) Partially movable- expands a little (ribs) 8. Where is cartilage found in the body? Ears, nose, ribs, between vertebrae, ends of bones What does it do? cushions 9. Complete the following chart about muscles: Type of muscle Where is it found? What does it move? Is it voluntary or involuntary? Skeletal Bicep, tricep, abs, quads… Bones Voluntary Smooth Digestive tract, blood vessels, etc Food, blood Involuntary Cardiac Heart Pumps blood Involuntary 10. What does a flexor do? Bends body parts 11. What does an extensor do? Straightens body parts 12. What are the 3 parts of the integumentary system? 1. hair 2. skin 3. nails 13. What are the 4 functions of the integumentary system? 1. regulates body temperature (sweat, blood vessels, hair) 2. removes waste (sweat) 3. protection (waterproof, UV light, germs out, water in…) 4. sensing the world (pressure, temp, pain) -nerves 14. Which 2 functions does our hair help with? 1. Protection (sun) 2. Body temperature regulation 15. Label the parts of the skin. 16. Write the function for each of the following: Hair Oil gland Epidermis melanocyte Sweat gland Dermis Hair follicle Muscle nerve Fat layer a. Sweat gland- makes sweat to cool off body and remove waste (salts) b. Oil gland- makes oil to waterproof and soften skin c. Nerve- sends electrical messages to sense temperature, pressure, pain… d. Blood vessel- transport nutrients, oxygen, waste, regulates body temp e. Hair follicle- make hair to protect, regulate body temp 17. How do muscles and tendons work together to move bones? What role do ligaments play in this movement? Nerves bring a message from the brain telling the muscle to contract The muscle contracts and pulls on the tendon The tendon pulls on the bone it is attached to The bone moves but the joint stays together because of the ligaments connecting the bones 18: Be able to discuss the labs that we have done and how they connect to what we have learned about the systems. -Sweating lab -Bone study National Geographic skin simulation
