The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe. Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed, according to the American Lung Association.
MAJOR HUMAN BODY SYSTEMS. Respiratory System Your respiratory system provides the energy needed by cells of the body. Air is breathed in through the nasal cavity and/or mouth and down through the throat (the pharynx). The throat has three parts-the nasopharynx, the oropharynx, and the laryngopharynx.our digestive system consists of organs that break down food into components that your body uses for energy and for building and repairing cells and tissues. Food passes down the throat, down through a muscular tube called the esophagus, and into the stomach, where food continues to be broken down.
