The human body is a complex and dynamic system made up of numerous organs and tissues that work together to maintain overall health and function. The nervous system, which includes the brain and spinal cord, plays a crucial role in regulating various bodily functions such as movement, sensation, and cognition. The circulatory system, on the other hand, is responsible for transporting blood throughout the body, delivering oxygen and nutrients to tissues and organs while removing waste products.
