The Hormonal System
The endocrine system controls internal bodily functions and is in charge of chemical coordination. Hormones are produced by the endocrine glands. Chemical messengers are called hormones. Since none of the endocrine glands have ducts, hormones are released into the bloodstream directly. Blood is abundant in each gland, facilitating the delivery of hormones to the intended organs. While proteins and lipids make up most hormones, others (such as the sex hormones) are only fat-based. Hormones do not carry out the action; rather, they regulate the target organ’s functions. Together, hormones function as a system that can either stimulate or inhibit different organs. In order to maintain the regular expansion, improvement, and coordinated operation of any system, processes are regulated. This coordination ensures that tissue fluid, nutrients, blood pressure, temperature, blood glucose levels, osmoregulation, temperature regulation, oxygen and carbon dioxide levels and salt concentrations (electrolytes) are controlled. The body is able to function at an optimum level.
