Many of us are born, live, and grow old, without ever really knowing how our body works. Our body is an amazing creation. Knowing about our body, and how it works, can help you maintain a strong and healthy body. Our body consists of many systems working individually, and together, to keep us alive. These systems include the cardiovascular system or circulatory system, digestive system, endocrine system, lymphatic immune system, muscular system, nervous system, reproductive system, respiratory system, sensory system, skeletal system, and urinary system. Check out the following sections to learn more about the human body, and how it works. For more detail, also see our Human Body Video Collection.
