|
|

-to allow the body to move -works hand in hand with skeletal system |
|
|
Skeletal system function |
-framework/structure/organs -protects internal organs -movement w/ muscular system -mineral storage (such as calcium) |
|
|
Levels of organization (skin) |
-skin cells to skin tissues to skin to integumentary system |
|
|
LOO (muscle) |
-muscle cell to muscle tissues to muscle to muscular system |
|
|
LOO (skeletal) |
-bone cell to skeletal tissue to bone to skeletal system |
|
|
Details (skin) |
-produces melanin (pigment produced by epidermis that gives skin, hair, and iris of the eye its color and protects skin from damage by ultraviolet from the sun) |
|
|
Details (muscles) |
-types of muscles (skeletal, smooth, cardiac) -tendon (tissue that connects muscle to bone) -voluntary movement (we have control, such as our arms and legs) -involuntary movement (we don't have control, such as our heart beating) |
|
|
Details (skeletal) |
-joint (where two or more bones meet) -ligaments (tissue that connects bone to bone) -tendons (tissue that connects muscle to bone) -cartilage (prevents bones from rubbing together and softens impact on the body, shock absorber) |
|
|
Analogy (skin) |
-skin is like the cell membrane |
|
|
Analogy (muscle) |
-muscles are like rubber bands |
|
|
Analogy (skeletal) |
-ribcage is like the cell wall |
|
|
PTK (skin) |
-three layers of skin (epidermis; top, dermis; middle, fatty layer; bottom) |
|
|
PTK (muscle) |
-biceps (top of arm, what you bulge to show off muscles) -triceps (back of arm or bottom of arm) -rectus abdominus (abs or stomach) -quadriceps (top of thigh) -hamstring (back of leg or thigh, behind knee, hurts when you pull it) |
|
|
PTK (skeletal) |
-head bone (cranium) -thigh bone (femur) -back bone (spine, contains vertebrae) -hip bone (pelvis) -shoulder to elbow (humerus) -ribs around chest (ribcage) -shin/knee to ankle (tibia) |
|
|
REMEMBER: CIRCULATORY |
-to transport blood w/ nutrients and waste throughout the body |
|
|
REMEMBER: RESPIRATORY |
-to exchange gas in the blood in the lungs (oxygen in and carbon dioxide out) |
|
|
REMEMBER: EXCRETORY |
-to remove waste from the body (feces, urine, sweat, and CO2) |
|
|
REMEMBER: DIGESTIVE |
-to break down large molecules into smaller ones to provide nutrients (energy) for the body's cells |
|
|
REMEMBER: ENDOCRINE & REPRODUCTIVE |
-endocrine (to control/regulate the body using chemical substances/hormones) -reproductive (to reproduce for survival of the species, produce make sperm and female egg cells, nurture and develop offspring, and produce hormones w/ the endocrine system) |
|
|
Work def |
Work is a force times a distance in the same direction. The force is moving an object a distance and that object is going the same direction as the force. |
|
|
Work Examples |
-throwing a ball -moving the same box w/ a ramp and without a ramp -pushing a stroller -picking up a chair -picking up a piece of tape |
|
|
Work Formula |
-W=FD -W=FxD -W=(F)(D) |
|
|
Work Unit |
-Joule (J) -J=Newton x meters |
|
|
Distance Example |
-Length |
|
|
Distance Units |
-Centimeters (Cm) -Inches (in) -Meters (m) |
|
|
Force Examples |
-Push -Pull -Movement |
|
|
Force Units |
-Newton (N) |
|
|
Not work examples |
-Climbing a rope -Standing still -Walking around with a chair -Carrying a baby -Pushing on a wall -No movement or not same direction |
|
|
Work 7.7A |
Contrast situations where work is done with different amounts of force to situations where no work is done such as moving the same box with a ramp and without a ramp onto a truck (same work), or standing still (no work). |
|
|
Daily Activities In Space |
-exercise (astronauts use treadmills with straps to keep them in place.) -sleep (sleeping bags that hold them in place and are strapped to the wall so they don't float into people) -toiletry (special toilets that use air flow to remove waste for storage or ejection into space. astronauts use towels to bathe and do not take showers.) -storage (objects can be kept in place using Velcro or straps. things like food need to be dehydrated or kept very small because space is limited.) -eating (they can eat liquids in little bubbles and eat dehydrated food. they don't have plates; food come in tubes.) -movement (they must use handles to move around from room to room. in space, they use thrusters to stabilize their direction on space walks.) |
|
|
Factors to have a planet be inhabitable |
-okay temperature -water -atmosphere composition -energy -nutrients |
|
|
Just Right Factors |
-good temp (life seems limited to a temp. range of minus 15 degrees C to 115 degrees C. in this range, liquid water can still exist under certain conditions.) -water (water is regularly available. life can go dormant between wet periods, but, eventually water needs to be available.) -atmosphere (earth & venus are the right size to have a sufficient-sized atmosphere. earth's atmosphere is about 100 miles thick. it keeps the surface warm & protects it from radiation & small to medium sized meteorites.) |
