1. Top Line (Head): The line points to the organ inside the skull. This is the control center of the body.
* *Match:* BRAIN

2. Upper Left Line (Chest): The line points to the large spongy organs on either side of the chest that help us breathe.
* *Match:* LUNGS

3. Upper Right Line (Center Chest): The line points to the muscular organ in the middle of the chest that pumps blood.
* *Match:* HEART

4. Middle Left Line (Upper Belly): The line points to the large, triangular-shaped organ on the right side of the upper abdomen (which appears on the left side of the drawing).
* *Match:* LIVER

5. Middle Right Line (Upper Belly): The line points to the J-shaped sac located just below the lungs where food goes after being swallowed.

8. Bottom Line (Outer Frame): The line points to the wider tube that frames the small intestine.
