The digestive system is responsible for breaking down food, absorbing nutrients, and eliminating waste, but it does not control hormone production or regulation. While it does include organs like the stomach and intestines that can secrete certain signaling chemicals — such as gastrin or ghrelin — these are not part of the broader hormone regulation system governed by the endocrine glands. The confusion may come from the fact that nutrition and digestion can influence hormone levels, but the digestive system’s primary function is mechanical and chemical digestion, not hormonal balance. The real regulatory power over hormones lies with the endocrine system, which works through the bloodstream to send chemical messages throughout the body. If you're talking about hormone control — think endocrine, not digestive.
