BONES AND MUSCLES - The muscular system is made up of all the muscles in the body and is responsible for the way we move. The skeletal system is made up of bones and other tissues. CIRCULATION & RESPIRATION - The circulatory system transports food, blood, and other important substances to the cells in your body. We need to breathe many times a minute to replenish our body with oxygen and to release waste products such as carbon dioxide and water vapor. The respiratory system is responsible for this process. DIGESTION & EXCRETION - Digestion is the process of breaking down food into simpler substances that the body can absorb. The process by which wastes are removed is called excretion. NERVOUS AND ENDOCRINE SYSTEM - The nervous system is the part of your body, which monitors and responds to changes in the environment. The endocrine system consists of glands that release chemicals called hormones into the bloodstream.
