  2. Has three major jobs: 1. It protects our vital organs such as the brain, the heart, and the lungs. 2. It gives us the shape that we have. 3. It allows us to move. Because muscles are attached to bones, when muscles move, they move the bones and the body moves. The Skeletal System

  3. Is made up of the mouth, esophagus, stomach, small intestine, and large intestine. The purpose of the digestive system is to break down food so that nutrients are absorbed by the body and to remove waste products from the body. Video The Digestive System

  4. The Cardiovascular System What is the cardiovascular system? What is the cardiovascular purpose? The organs and tissues involved in circulating blood through the body. To carry blood, oxygen and nutrients to all of the body.

  5. The Muscular System: The body has more than __?__ muscles. Moves the body. Muscles move by contracting, or becoming shorter. Muscles attached to the bones move the arms, legs, fingers, and other parts of the skeleton. Another type of muscle is found in most of the organs inside the body. This type of muscle works automatically to make the organs, such as the stomach, work. The heart is made of a special type of muscle. When heart muscles relax, blood from the body enters the heart. The muscles quickly tighten up to squeeze the blood back out again. This action is called a heartbeat. The heart beats about 70 times each minute. A 400 500 600 B C
