The Endocrine System   The endocrine system affects bodily activities by releasing chemical messengers, called  hormones, into the bloodstream. The system as a whole sends messages to cells in virtually any  part of the body. It not only helps to regulate the activity of smooth and cardiac muscle and some  glands, it significantly affects virtually all other tissues as well. Endocrine organs are widely  scattered throughout the body.   The nervous and endocrine systems coordinate their activities and together are considered the  control systems of the body.    The Ways Hormones Affect Targets Although the effects of hormones are many and varied, their actions can be categorized into 5  broad areas: 1. Help control the internal environment by regulating its chemical composition and volume. 2. Respond to changes in the environmental conditions to help the body cope with  emergency demands such as infection, trauma, emotional stress, dehydration, starvation,  hemorrhage, and temperature extremes. 3. Integration of growth and development. 4. Contribute tot he basic processes of reproduction. 5. Help regulate organic metabolism and energy balance.   Definition of Endocrine and Exocrine There are two kinds of glands in the body:  endocrine and exocrine 1. Exocrine glands have ducts through which their non-hormonal products are routed to a  membrane surface. Examples are sweat, sebaceous, mucous, and digestive glands. 2.
