CHAPTER II
PARTS OF THE BODY
Regions of the Body.—In order to talk about any part of the body it must have a name. The main portion of the body is called the trunk. At the top of the trunk is the head. The arms and legs are known as limbs or extremities. The part of the arm between the elbow and wrist is the forearm. The thigh is the part of the leg between the knee and hip.
The upper part of the trunk is called the chest and is encircled by the ribs. The lower part of the trunk is named the abdomen. A large cavity within the chest contains the lungs and heart. The cavity of the abdomen is filled with the liver, stomach, food tube, and other working parts.
The Plan of the Body.—All parts of the body are not the same. One part has one kind of work to do while another performs quite a different duty. The covering of the body is the skin. Beneath is the red meat called muscle. It looks just like the beef bought at the butcher shop which is the muscle of a cow or ox. Nearly one half of the weight of the body is made of muscle.
