Biology exam Endocrine system: Hormones: chemical messengers that coordinate the body’s activates. Substances secreted by cells that act to regulate the activity of other cells in the body. They are part of the endocrine system and they are slow acting but have a longer affect than neurotransmitters. Functions: * regulate growth‚ development‚ behavior‚ and reproduction. * Maintain homeostasis * Regulate metabolism and water and mineral balance * Respond to external stimuli

The Endocrine System: 1. What is the Endocrine System? •The Endocrine System influences almost every cell‚ organ‚ and function of our bodies. •It is a collection of glands and organs that produce and regulate hormones in the bloodstream to control many bodily functions. •Whereas the nervous system responds to and controls body processes which occur quickly and last for a short amount of time‚ the endocrine system is responsible for many of the slow

The field of study dealing with the endocrine system and its disorders is endocrinology‚ a branch of internal medicine. The endocrine system is an umbrella term used to describe the complexity of different types of endocrine glands which are responsible to help the body carry out many of its functions. This system regulates our mood‚ growth‚ metabolism‚ tissue development‚ sexual functions and reproductive process. The endocrine system is made of a series of glands that produce chemicals

The Endocrine System Sarah Horton Texas Woman’s University Introduction The endocrine system is one of two systems in the human body that regulates all bodily functions. It is comprised of organs called endocrine glands and include the ovaries‚ testes‚ pituitary‚ hypothalamus‚ pineal‚ pancreas‚ kidneys‚ thyroid‚ parathyroid‚ thymus‚ and adrenal glands. These glands‚ which are spread throughout the body‚ are responsible for the extensive and enduring release of certain hormones into the bloodstream

The foundations of the Endocrine System consist of hormones and glands. These glands are ductless and their secretions are sent through the bloodstream. Endocrine glands also control bodily metabolic activity. The major glands that make up the human endocrine system are the hypothalamus‚ pituitary‚ thyroid‚ parathyroids‚ adrenals‚ pineal body‚ the pancreas‚ and the reproductive glands‚ which include the ovaries and testes. The endocrine system has three basic functions‚ regulate metabolic functions

CHEMICAL SIGNALS MAINTAIN HOMEOSTASIS Endocrine System: a system of glands that secrete hormones to regulate body function Hormones: chemical messengers or regulators • they are released by cells in one part of the body and affect cells in other parts of the body to speed up or slow down processes. Endocrine Hormones – are produced in glands and secreted directly into the blood and distributed by the circulatory system. Makes hormones and regulates the pituitary gland Pineal gland (makes serotonin

Its function is to regulate metabolism and secrete

The Relationship Between The Nervous System and The Endocrine System The cells and tissues in the body are delicate and easily disrupted. They will only be able to function well if all aspects of their chemical and physical environment is continuously adjusted to keep them stable and in equilibrium. The process in which several body systems work together to maintain the balanced environment is called homeostasis. The endocrine and nervous system work closely together to help maintain homeostasis
