6. Nervous System The nervous system is responsible for sending, receiving, and processing nerve impulses throughout the body. Click on the picture that is part of the nervous system. Brain Kidney

7. Excretory System The excretory system gets rid of waste that the body does not need. Click on the picture that is part of the excretory system. Lungs Kidney

8. Circulatory System The circulatory system is a transport system that moves substances through the body. Click on the picture that is part of the circulatory system. Heart Brain

9. Immune System The immune system defends you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body.

10. Reproductive System The reproductive system is responsible for producing offspring. The male and female organs are quite different in structure and function.

11. Digestive System The digestive system breaks down food to be used in the body. Click on the picture that is part of the digestive system. Great Job! This picture is of Several organs that are in the digestive system

12. Digestive System The digestive system breaks down food to be used in the body. This is a picture of the heart, its function has nothing to do with the breaking down of food

13. Respiratory System The respiratory system supplies the blood with oxygen which in turn carries oxygen to the body parts. Lungs The skull is a type of bone. Click the back arrow to try again

14. Respiratory System The respiratory system supplies the blood with oxygen which in turn carries oxygen to the body parts. Click on the picture that is part of the respiratory system. Skull Great job! Keep going!

15. Muscular System The muscular system provides both voluntary and involuntary movement for the body Heart Good try. However, the brain is an organ with no muscle. Try again.

16. Muscular System The muscular system provides both voluntary and involuntary movement for the body Click on the picture that is part of the muscular system. Brain Great job! The heart is an involuntary muscle. Keep going!

17. Nervous System The nervous system is responsible for sending, receiving, and processing nerve impulses throughout the body. Click on the picture that is part of the nervous system. Great job! The brain is the control center of the body. Keep going.

18. Nervous System The nervous system is responsible for sending, receiving, and processing nerve impulses throughout the body. Sorry, the kidney’s job is to filter waste from the body. Try again

19. Skeletal System The skeletal system is responsible for support and protection of the other body organs. The brain is an organ that the skeletal system protects. Try again.

20. Skeletal System The skeletal system is responsible for support and protection of the other body organs. Click on the picture that is part of the skeletal system. Very nice. The skull protects the brain. Keep going!

21. Excretory System The excretory system gets rid of waste that the body does not need. Click on the picture that is part of the nervous system. Lungs Great job! The kidneys do help eliminate waste from the body. Keep going!

22. Excretory System The excretory system gets rid of waste that the body does not need. The job of the lungs is to put oxygen in the blood. Try again. Kidney

23. Circulatory System The circulatory system is a transport system that moves substances through the body. Heart Not quite! The brain is in charge of controlling the body. Try again.

24. Circulatory System The circulatory system is a transport system that moves substances through the body. Click on the picture that is part of the circulatory system. Great job! The heart is a muscle that pumps the blood through the body. Brain
