  1. The Body Growth and Development By: Elizabeth Budd

  2. The Nervous System Carries messages to and from the brain and all other parts of the body and helps cause our reflexes • Brain: control center of the body • Spinal Cord: carries messages between the brain and the body • Nerve Cells: a small unit of the nervous system

  3. The Cardiovascular System Moves nutrients, hormones, and gases throughout the body • Blood: carries nutrients, oxygen and other things to cells • Blood Vessels: tubes that carry blood throughout the body • Heart: muscle that pumps blood throughout the body

  4. The Immune System Removes bad organisms from the blood and fights sickness • Lymph Node: structure that kills sickness • Spleen: filters bad things from the blood • Thymus Gland: causes white blood cells to become T-cells that kill off sickness

  5. The Respiratory System Provides body cells with oxygen and removes carbon dioxide • Trachea: tube where air moves to the lungs • Bronchi: two tubes that air goes through after the trachea to the lungs • Lungs: main organs • Cilia: smalls hairs that remove dust from the air we breath

  6. The Muscular System Consists of muscles that provide motion and maintain posture • Voluntary Muscles: muscles you can control • Arms, legs • Involuntary Muscles: muscles you cant control • stomach, lungs

  7. The Skeletal System Serves as the frame of your body, protects your organs, and works with muscles so you can move! • Bones: hard material of the skeletal system • Bone Marrow: the tissue inside of your bones • Cartilage: tissue at the end of your bones that helps connect some bones • Ligaments: tough fiber that connects some bones • Joints: where two bones meet
