The Human Anatomy and Possible Threats - Essay Example This section presents the systems of the human body and how they function in swift collaboration. The section aims to reveal how each of the various organ systems is equally important in enabling human beings to function as complete beings. The main systems of the human body are the cardiovascular system, the digestive system, the endocrine system, the urinary system, the immune system, the muscular system, the nervous system, the reproductive system, and the respiratory system (Schlossberg and Zuidema, 2007). Wolfsthal (2008) argues that all the mentioned systems work in harmony to ensure that the body maintains a steady state with sufficient nutrients and oxygen, as well as the correct temperature and the right pH level (level of acidity or basicity of the body) ((Steding, 2009). The circulatory system is responsible for the circulation of blood and lymph around the body (Swearingen, 2012). The circulation in turn transports oxygen, carbon dioxide, nutrients, hormones, and other su bstances to and from the body (Wolfsthal, 2008). This phenomenon can also be referred as Cellular Metabolism (Waller and Lloyd, 2008). Cellular Metabolism can be defined as the cumulative sequence of biochemical reactions, which occur within a cell. The reaction is responsible for the production of Adenosine Triphosphate (ATP-the molecule which stores all the energy derived from food). Cellular metabolism also enables processes like respiration and the disposal of waste products from the body.
