The human body is made up of approximately 60 trillion cells. These cells work together to form organs and tissues that make up various systems within the body. The nervous system consists of the brain, spinal cord, and nerves, which transmit messages between different parts of the body. The circulatory system transports blood throughout the body, supplying oxygen and nutrients to cells and removing waste products. The muscular system allows for movement through voluntary and involuntary muscle contractions. The skeletal system provides support and structure to the body, while the integumentary system protects it from external damage. Other systems include the endocrine system, which regulates hormone production; the digestive system, which breaks down food into nutrients; and the immune system, which defends against pathogens.
