Final answer:
Muscles, skeleton, and hormone-producing glands assist in physical change in the body.
Step-by-step explanation:
Three organs that assist in physical change in the body are the muscles, skeleton, and hormone-producing glands.
The muscles allow movement and physical change by contracting and relaxing. They enable us to walk, run, lift objects, and perform other physical activities.
The skeleton provides structural support to the body and aids in physical change by allowing movement. It consists of bones, joints, and connective tissues.
The hormone-producing glands, such as the pituitary gland, thyroid gland, and adrenal glands, secrete hormones that regulate various processes in the body, including growth, development, and physical changes during puberty.
