how the body systems work together
The Systems. Several systems in the human body work together to help keep it functioning normally. These systems are the skeletal, muscular, digestive, respiratory, circulatory, urinary, endocrine, lymphatic, immune, reproductive and the nervous.
The respiratory system also works closely with all other systems of the body. The respiratory system provides oxygen for all body parts. It also removes carbon dioxide from the muscular, digestive, skeletal, circulatory, urinary and nervous systems. This system includes the nose, larynx, trachea and the lungs.
The urinary system also works closely with all other systems of the body. It is used to clean blood from the body. This system cleans waste products from the skeletal, muscular, digestive, respiratory, circulatory and nervous systems. The system includes the kidneys and lower intestines.
