The human body is a complex machine that relies on a delicate balance of systems to function properly. The nervous system, which includes the brain and spinal cord, sends and receives signals throughout the body, controlling everything from movement to emotions. The circulatory system, made up of the heart, blood vessels, and blood, delivers oxygen and nutrients to cells and carries away waste products. The respiratory system, composed of the lungs, trachea, and bronchi, brings oxygen into the body and removes carbon dioxide. The digestive system, which includes the mouth, esophagus, stomach, small intestine, and large intestine, breaks down food into nutrients that can be absorbed by the body. The immune system protects against pathogens and disease, while the endocrine system produces hormones that regulate various bodily functions.
