The five regions of the body include the head, neck, torso, upper extremities, and lower extremities. The head region includes the skull and face. The torso, also called the trunk, consists of the chest, abdomen, and pelvis. The upper extremities include the arms, armpits, and shoulders. Finally, the lower extremities consist of the legs, buttocks, thighs, knees, ankles, and feet. Dividing the body into these regions makes locating and describing a specific part of the body easier. For example, when describing the relative location of the heart, it is said to be in the torso region of the body.
