The endocrine system is a control system of ductless glands that secrete chemical "instant messengers" called hormones that circulate within the body via the bloodstream to affect distant cells within specific organs. Endocrine glands secrete their products immediately into the blood or interstitial fluid‚ without storage of the chemical. Hormones act as "messengers‚" and are carried by the bloodstream to different cells in the body‚ which interpret these messages and act on them. Typical endocrine

The endocrine system refers to the different organs of the body that are responsible for secreting hormones that affect bodily processes. Better known for their ability to process waste‚ the kidneys are responsible for the secretion of four different hormones: rennin‚ calcitriol‚ erythropoietin and thrombopoietin These chemicals released by the kidneys affect a wide range of bodily processes dealing with the circulatory and skeletal systems. Understanding the endocrine functions of the

Invertebrate Endocrinology Overview of the Endocrine System * System of ductless glands that secrete hormones * Hormones are “messenger molecules” * Circulate in the blood * Act on distant target cells * Target cells respond to the hormones for which they have receptors * The effects are dependent on the programmed response of the target cells * Hormones are just molecular triggers * Basic categories of hormones * Amino acid based: modified amino acids (or amines)

Human Endocrine System A system of glands and cells that make hormones that are released directly into the blood and travel to tissues and organs all over the body. The endocrine system controls growth‚ sexual development‚ sleep‚ hunger‚ and the way the body uses food. [pic] The human endocrine system modulates several processes of the body by the function of hormones. The endocrine system secretes hormones that control how bodily functions work. Thus‚ the human endocrine system watches

The Endocrine System System Although we rarely think about them‚ the glands of the endocrine system and the hormones they release influence almost every cell‚ organ‚ and function of our bodies. The endocrine system is instrumental in regulating mood‚ growth and development‚ tissue function‚ and metabolism‚ as well as sexual function and reproductive processes. In general‚ the endocrine system is in charge of body processes that happen slowly‚ such as cell growth. Faster processes like breathing

Applied Human Science – CHAPTER 1 1. Which Organ system maintains a relatively slow-acting degree of control over most bodily functions? Endocrine System (hormones act in minutes to hours‚ in contrast to nerve impulses‚ which act in fractions of a second). 2. The esophagus and the trachea run side-by-side through the thorax. In which systems are these organs found? The esophagus belongs to the digestive system‚ and the trachea belongs to the respiratory system. (The esophagus carries food to the
