Answer 1

Answer:

1. Skeletal system
2. Your small intestine also breaks down food using enzymes made in your pancreas and bile from your liver. The small intestine is the "work horse"' of digestion -- while food is there, nutrients are absorbed through the walls and into your bloodstream.
3. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body.
4. Nerves are a part of the nervous system. They are primarily involved in control and the coordination of all the parts of the body. The nervous system not only sends and receives messages but also processes them into chemical signals called impulses in the human body.
