It is thanks to it that we do not think about how the heart beats or the stomach functions. In this article, we will consider its structure, functions and connection with many diseases.<\/p>\n<h2 data-start=\"601\" data-end=\"643\">Structure of the autonomic nervous system<\/h2>\n<p data-start=\"645\" data-end=\"758\">The ANS consists of two main divisions that often act in opposite directions, creating a dynamic balance:<\/p>\n<ul data-start=\"760\" data-end=\"1109\">\n<li data-start=\"760\" data-end=\"919\">\n<p data-start=\"762\" data-end=\"919\"><strong data-start=\"762\" data-end=\"784\">Nice department<\/strong> \u2014 activates the body in response to stress (\u00abfight or flight\u00bb).
