Digestive system

• Your digestive system consists of organs that
  break down food into component that your body
  uses for energy. Food passes down the throat down
  through a muscular tube called the esophagus
  duodenum. The jejuna and ileum are also a part of
  the small intestine. The liver, the gallbladder,
  and the pancreas produce enzymes. The digestive
  system helps us in much more things than that.

Circulatory system

• The heart, the lungs, and the blood vessels work
  together to form the circle part of the
  Circulatory system. Your circulatory system
  consists of your heart and blood vessels. Your
  arteries carry blood away from the heart.
  Arteries that branch off the aorta transport
  blood throughout the body.

Nervous system

• Made up of your brain, your spinal cord, and an
  enormous network of nerves that thread throughout
  your body, it's the control center for your
  entire body. Your brain uses information it
  receives from your nerves to coordinate all of
  your actions and reactions. Without it, you
  couldn't exist! They're the thin threads of nerve
  cells, called neurons that run throughout your
  body. Bundled together, they carry messages back
  and forth just the way that telephone wires do
