Answer Key

#	Answer
1	A body system is a group of organs that work together to do a major job in the body.
2	The muscular system helps control movement.
3	The skeletal system supports the body and protects important organs.
4	A sensor is a device that detects or measures information from the world around it.
5	A health device can measure heart rate.
6	It measures how many times the heart beats in a minute.
7	It collects steps to track activity and help a person monitor exercise.
8	Doctors use computers to store, analyze, and compare body information.
9	Data is information that can be collected, stored, and processed.
10	It can measure body temperature.
11	The nervous system sends messages through the body and helps control actions.
12	A computer model can show body parts and systems in a visual way, making them easier to understand.
13	Input is information that enters a computer from a user or device.
