The human body is a complex and dynamic system made up of trillions of cells, organs, and tissues that work together to maintain homeostasis and overall health. The human nervous system consists of the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which includes nerves that connect the CNS to the rest of the body. The human heart is a vital organ responsible for pumping blood throughout the body. It pumps around 2,000 gallons of blood per day and beats approximately 100,000 times per day. The human lungs are responsible for exchanging oxygen and carbon dioxide through the process of respiration. They expand and contract to take in oxygen-rich air and expel carbon dioxide. The human digestive system is a complex network of organs that work together to break down food into nutrients that can be absorbed by the body. It includes the mouth, esophagus, stomach, small intestine, and large intestine. The human immune system protects the body from pathogens such as bacteria, viruses, and other foreign substances. The human skeletal system provides structural support and protection for the body's internal organs. It consists of 206 bones that are connected by ligaments, tendons, and joints. The human muscular system is made up of over 640 muscles that work together to move the body's skeleton.
