Each part of the arm has a function, and all of the parts work together as a system. If any part of the system is missing, then the system won’t work the same way anymore. Read the following statements about what might happen when a part of the system is removed. Circle all that are correct. There may be more than one correct answer.

• If the muscle is missing, the arm won’t have any structure at all anymore because muscles are what give arms their structure.

• If the tendon is removed, the arm will still have its shape. But the muscle won’t be able to move the arm anymore because the muscle won’t be attached to the bone.

• If the bones are removed, the arm won’t have any structure at all anymore because bones are what give arms their structure.

• If the muscle and tendon are removed, the arm will still have most of its shape. But it won’t be able to move at all, because muscles make arms move.
