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 and body movement are controlled by the nervous system. But even though the nervous system and endocrine system are separate systems, they often work together to help the body function properly.
The foundation of the endocrine system are the hormones and gland. As the body's chemical messagers, hormones transfer information and instruction from one set of cells to another. Although many different hormones circulate through out he bloodstream, each one affects only the cells that are genetically programmed to receive and respond to its message. Hormones levels can be influenced by factor such as stress, infection, and changes in the balance of fluid and minerals in blood.
A gland is a group of cells that produces and secretes, or gives off, chemicals. A gland selects and removes materials from blood, processes them, and secretes the finished chemical product for use somewhere in the body.
Some types of glands release their secretions in specifics areas. For instance, exocrine glands, such as the sweat and salivary glands, release secretion in the skin or inside of the mouth. Endocrine gland, on the other hand, release more than 20 major hormones directly into the bloodstream where they can be transported to cells in other parts of the body.
