| Nervous System Functions | Helps us gather, relay, interpret, and use information. It also allows us to make all movements and decisions. |
| Bone covering | Protects the bone and helps it heal |
| Blood vessels | brings in nutrients and wastes out |
| Compact Bone | Strong dense part that makes up 80% of skeleton |
| Yellow Marrow | It fills center of bone and stores fat |
| Spongy bone | contains many tiny holes and red marrow is stored here |
| Red Marrow | It is found in the spongy bone and it is responsible for producing red blood cells |
| Functions of the digestive system | break down food into nutrients that cells can use and pull nutrients out or and into the blood stream |
| Cell body | Keeps the nerve cell alive and functioning |
| Axon | Send information to other nerve cells |
| Dendrites | Tiny branching fibers that spread out in all directions and gather information |
| Spinal Cord Function | Relays signals between the brain, muscles, and organs. It can also relay signals directly from the sensory nerve to motor nerve. |
| Brain stem | Part of the brain thta connects the brain and the spinal cord. It controls the bodies automatic function. |
| Cerebellum | Smaller portion of the brain that coordinates the motions of the voluntary muscles |
| Cerebrum | Largest part of the brain that interprets, stores, and sends information. It deals mostly with our senses. |
| Sensory nerves | Gather information to make us aware of our surroundings. |
| Motor Nerves | It takes messages from the brain and brings them to our muscles and our organs |
| Brain | It interprets all the information that sensory nerves gather |
| Nervous system structures | The brain, spinal chord, and all nerves through the body. |
| Structures of the Urinary System | 2 kidneys, 2 uterers, a bladder, and a uretha |
| Kidney | Filters blood |
| Ureters | Carry wates from the kidneys to the bladder |
| Bladder | Stores the urine |
| Uretha | Carries waste from the body |
| Functions of the Urinary System | REmoves waste from our blood and removes waste from our body. |
| Cilia | Tiny hairlike fibers that line passages of the respitory system. They trap impurities in the inhaled air. |
| Trachea | The tube that branches off from the throat and carries air toward the lungs. It is also known as the wind pipe. |
| Diaphragm | The dome shaped muscle below the rib cage. It contracts when we inhale and relaxes when we exhale |
| Respitory System Functions | To bring oxygen in, remove carbon dioxide, and to clean the air that we breathe. |
| Respitory System Structures | mouth, nose, epiglottus, trachea, bronchial tubes, lungs, and air sacs |
| Mouth | Breathe in through |
| air sacs | There are over 300 million of these |
| Cell membrane | A membrane that surrounds the cell, holds everything together, and controls what enters or leaves the cell |
| Nucleus | The brain of the cell |
| Cytoplasm | Jelly-like substances that fill the inside of the cell. It holds other structures in place. |
| Cells | The basic unit of the body |
| Small intestine | where majority of digestion takes place |
| Functions of the Skeletal System | Gives the body shape, aids muscular system in the movement of the body, and protects vital organs |
| The 3 main protective parts of the skeletal system | Cranium, backbone, and ribs |
| Function of muscula system | movement, shape, and functions of our organs |
| Ball & Socket joint | hip and shoulder |
| Hinge joint | elbow and knee |
| Gliding joint | Wrist and ankle |
| Pivot joint | neck |
| Fixed or immoveable joint | skull or face |
| Skeletal muscles | body movement and shape - an exampe is the bicep |
| Smooth muscles | organ function and it is involuntary - an example is the stomach |
| Cardiac muscle | heart function & it is involuntary |
