    24: The Nervous System The Skeletal System and The Muscular System The Nervous System fires electrical signals to your muscles, galvanizing them into action and making them move. The Skeletal System helps to support the Muscular System and move blood throughout your body so your body can receive oxygen. Your Muscular System in turn keeps your heart beating and helps you with locomotion.
    25:The functions of the circulatory system by which the cells are supported include: 1. Respiration- oxygen is delivered to the cells and carbon dioxide is removed from them. 2. Nutrition- nutrients for energy are supplied to every cell in the body. 3. Waste removal- metabolic waste products are taken away before they accumulate and become harmful to the cells. 4. Cellular communication- hormones are transported to the cells and organs that need them for proper functioning. 5.Thermoregulation- As blood circulates, it keeps body temperature balanced and thus cells are able to carry out processes well.
    4:C
    5:B
    Besides those two, Mystery Man got it right.
