Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body.                     The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction.The endocrine system regulates how much of each hormone is released. This can depend on levels of hormones already in the blood, or on levels of other substances in the blood, like calcium.Many things affect hormone levels, such as stress, infection, and changes in the balance of fluid and minerals in blood.
