What Are Hormones?
Hormones are chemical messengers in the human body. These molecules are released by the endocrine system and help send signals through the bloodstream to different body parts. They play many important roles in controlling major processes, such as sexual desire, blood pressure, hunger, or metabolism. Hormones can flow through the entire body, but only a few cells are able to receive their signals. In general, receptor sites and hormones work like a key and a lock. Many health issues might occur when hormone levels fluctuate, which can be the result of underlying conditions or natural aging. [1]
