EduRev Tips:

  • The skeletal system works as a support structure for your body. 
  • Bones shape our body and help us to stand up straight. Muscles are attached to bones; they help us walk and run and smile.
  • We cannot bend our body at every body part. The body can be bent only at the joints.

EduRev Tips:

  • The heart is a hard-working muscle, and its job is to pump blood throughout life.
  • Bones don't work alone — they need help from the muscles and joints. Muscles pull on the joints, allowing us to move. They also help the body perform other functions so we can grow and remain strong, such as chewing food and then moving it through the digestive system.
  • Hinge joints, such as in the fingers, knees, elbows, and toes, allow only bending and straightening movements.
