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
