Every living thing needs energy in order to live. Everytime animals do something (run, jump) they use energy to do so.
Animals get energy from the food they eat, and all living things get energy from food. Plants use sunlight, water and nutrients to get energy in a process called photosynthesis.

Headache... Why do I have a pain? Waking up with a sore throat that really hurts when you swallow. Jamming your finger at basketball practice. Playing a video game for so long that your wrist aches. These situations are different, but they have one thing in common: They all make you say "ouch!" 
When your body is injured in some way or something else is wrong, your nerves (cells that help your body send and receive information) send millions of messages to your brain about what's going on. Your brain then makes you feel pain. So if you put your hand on a hot stove, your nerves call your brain, and your brain quickly sends the message that your hand hurts. You get this message and pull your hand away from the hot stove, which saves your hand from further injury.

3. Endocrine system

Problems with the endocrine system: Too much or too little of any hormone can be harmful to the body. For example, if the pituitary gland produces too much growth hormone, a child may grow excessively tall. Another problem is when the pancreas fails to procude enough insulin (a gland useful in glucose digestion), then appears the "diabetes". Have you ever listen about that problem?
