Mini Lesson

Your body is an incredible machine. Every part has a job to do, and all the parts work together as a team. Let's learn the seven main external parts of the human body.

Head

  • The head sits at the top of the body. It contains the brain — the control center for everything you think, feel, and do.
  • The face is on the front of the head: eyes, ears, nose, and mouth.

Neck

  • The neck connects the head to the rest of the body. It lets you turn and tilt your head.
  • Inside the neck are important tubes for breathing and swallowing.

Torso (trunk)

  • The torso is the main part of the body between the neck and the hips. It includes the chest and belly.
  • Inside it are vital organs: heart, lungs, stomach, and liver.

Arms and hands

  • Two arms attach to the shoulders on either side of the torso. They let us reach and lift.
  • At the end of each arm are hands with fingers — used for gripping, writing, and touching.

Legs and feet

  • Two legs attach to the hips at the bottom of the torso. They support our weight and let us walk, run, and jump.
  • At the end of each leg are feet with toes — used for balance and pushing off the ground.
