All the systems in the human body are vital to our survival and well-being. If you take away the functions of just one of these systems our whole body will cease to work properly. The main systems of the human body are the nervous, endocrine respiratory, circulatory, immune, digestive, excretory, skeletal, muscular, and the reproductive systems. They all work together in harmony and unison to keep us alive. The nervous and endocrine systems are what control most of the body. The nervous system includes the brain, spinal, cord and nerves. The endocrine system consists of various hormonal glands such as the pituitary. These two systems interact closely since they both have a part in controlling

The digestive system aids the circulatory system by supplying blood with nutrients. It also kills the bacteria caught in mucus and therefore helps both the respiratory and immune systems. The excretory system helps the circulatory system by performing homeostasis in the kidneys and keeping the blood balanced. It also disposes of all the wastes from the body.
These two systems keep the body well fed and clean. The skeletal and muscular systems are the main support for the body. The skeletal system includes all the bones in the body. It is divided into the axial and appendicular skeleton. It supports the main structure of the body. The muscular system consists of all the muscles in the body. It is located on the bones and moves them. The skeletal system protects the respiratory, circulatory, nervous, and digestive system with structures such as the rib cage and the skull. The respiratory system is also helped because bone marrow produces red blood cells. The skeletal system also holds all of the other systems together. The muscular system helps the nervous system by giving it control of almost the whole body. The heart of the circulatory system is also a muscle. The respiratory System is helped with inhaling and exhaling through the movement of muscles. The integumentary system is also a system that is closely related to those of the skeletal and muscular. It consists of
