What+part's+make+up+the+body's+system?

You probably know that you have a heart, a stomach, and two lungs. Each of those body parts is an organ. If you could see inside your body, you would have no trouble telling the organs apart. Your heart looks very different from your stomach, your lungs, and all of your other organs. Your heart also does its own special job of pumping blood. No other organ does that. Each organ in your body has its own special job. ** Organ: ** a body part that does a special job within a body system.

**1- Name the six major body systems.**
 * Leen: 1) nervous system 2) circulatory system 3) respiratory system 4) excretory system **
 * 5) reproductive system 6) muscle/skeletal system **

[Dalia] Nervous System, Circulatory System, Digestive System, Endocrine System, Skeletal System, Respiratory system.

**2- How is an organ different from a system?**
 * Leen: an organ works within a system whereas a system contains more than **
 * one functioning organ in order for the body to function. **

** [Dalia] An organ is part of a system, and a system contains many organs. **

**Bonus Question!**

**3- In which body system would you find the following organs: blood, the windpipe, the skull, the brain?**  Leen: Blood (circulatory system), Windpipe (respiratory system), Skull (skeletal system), Brain (nervous system) ** [Dalia] Blood is in the circulatory system, the windpipe is in the respiratory system, skull's part of the skeleton, and the brain is in the nervous system. **

Vanessa:
 * 1) The six major body systems:
 * The respiratory system
 * The circulatory system
 * The digestive system
 * The skeletal system
 * The muscular system
 * The nervous system
 * 1) The system is a group of body parts or organs that work together to perform a job, where as the organ is the body part that does the specific job with in the body system.
 * 2) Blood in the circulatory system, the windpipe in the respiratory system, the skull in the skeletal system, and the brain in the nervous system.
