| Functions of the Urinary System | 1) removes wastes from our blood; 2) removes waste from our body |
| Structures of the Urinary System | 2 kindeys, bladder, urethra, and 2 ureters |
| kidneys | filter our blood |
| ureter | carries waste from the kidney to the bladder |
| bladder | stores the urine |
| urethra | carries urine out fo the body |
| Functions of the Nervous System | 1) helps gather, relay, interpret, and use information; 2) Allows us to make movements and decisions |
| Structures of the Nervous System | the brain, the spinal cord, and all nerves through the body |
| How the nervous system works | 10 sensory nerves gathers information and makes us aware of our surroundings; 2) the brain interprest the information and 3) mocler nerves take messages from our brain to our organs |
| brain | interprets all the information that sensory nerves gather |
| cerebrum | the largest part of our brain; it interprets, stores, and sends information; deals mainly with our senses |
| cerebellum | a small part of our brain that coordinates the motions of voluntary muscsles |
| brain stem | part of the brain that connects the brain to spin; it controls the body's automatic functions (heart beat and breathing) |
| Functions fo the Spinal Cord | 1) relay signal between your brain to your muscles and organs; 2) relay signals directly from sensory nerves to mocler nerves |
| Structures of Nerve Cells | dendrite, cell body, and axon |
| dendrite | tiny brancing fibers spreading out in all directions; gather information |
| cell body | keep the cell alive and functioning |
| axon | sends information to the other nerve cells |
| motor nerves | takes messages from the brain and brings them to our muscles and our organs |
| sensory nerves | gather information to make us aware of our surroundings |
| ureters | carries waste from kidneys to the bladder |
