Although we rarely think about them, the gland of the endocrine system and – the hormones that they release – influence almost every cell, organ and function in the human body. The endocrine system is key in regulating mood, growth and development, tissue functioning and metabolism among many other functions.

Generally speaking, the endocrine system is in charge of body processes that happen slowly, for example cell growth. Faster processes – such as breathing and body movement – are regulated by the nervous system. However, even though the nervous system and endocrine system are separate they often work together to help the body function properly.

About The Endocrine System

The foundations of the endocrine system are hormones as well as glands. As they are the body’s chemical messengers, hormones transfer information and instructions from one set of cells to another. Although many different hormones circulate throughout the bloodstream each one only affects the cells that re genetically programmed to received as well as provide a response to its message. Levels of hormone can be influenced by factors such as stress, infection and changes in the balanced of fluid as well as minerals in blood.

A gland is a collection of cells which produces and secretes (or give off) chemicals. A gland selects and takes out materials from the blood. It then processes these materials and secretes the finished chemical product that will be used somewhere else in the body.

A number of types of glands release their secretions in specific areas. For instance, exocrine glands, such as salivary and sweat glands, are responsible for releasing secretions in the skin or inside of the mouth. Endocrine glands, conversely, release more than 20 major hormones directly into the bloodstream. Using this medium they can be transported to cells in other parts of the body.

Parts of the Endocrine System

The main glands that constitute the human endocrine system are the hypothalamus, pituitary, thyroid, parathyroid, adrenals, pineal body and the reproductive glands. In men, the reproductive glands are the testes and in women the reproductive glands are the ovaries. The pancreas also forms a part of this hormone-secreting system. This is even though it is also associated with the digestive system as it also produces as well as secretes digestive enzymes.

Even though the endocrine glands are the body’s main hormone producers some non-endocrine organs -such as the brain, heart, lungs, kidneys, liver, thymus and skin – also produce and release hormones.
