Hormone receptors are dynamic structures. Changes in the number and sensitivity of hormone receptors may occur in response to high or low levels of stimulating hormones. Blood levels of hormones reflect a balance between Hormone half-life and duration of activity are limited and vary from hormone to horm...

The endocrine system consists of a group of glands and organs that regulate and control various body functions by producing and secreting hormones. Hormones are chemical substances that affect the activity of another part of the body. In essence, hormones serve as messengers, controlling and coordinating activities throughout the body. The hypothalamus (a small region of the brain that connects to the pituitary gland) secretes several hormones that control the pituitary gland. The Pituitary: The Master Gland is sometimes called the master gland because it secretes hormones that Endocrine Controls The main function of endocrine glands is to secrete hormones directly into the bloodstream. Hormones are chemical substances that affect the activity of another part of the body (target site)... read more . During pregnancy, the placenta also acts as an endocrine gland by producing hormones that support the pregnancy in addition to its Development of the Fetus and Placenta A baby goes through several stages of development, beginning as a fertilized egg.

Not all organs that secrete hormones or hormone-like substances are considered part of the endocrine system. For example, the kidneys produce the hormone renin, which functions as an enzyme to help control blood pressure, and the hormone erythropoietin to stimulate the bone marrow to produce red blood cells...
