Are hormones secreted only by endocrine glands

Can the digestive juices be called hormones? Why/ Why not?

NO, they are secreted by eno as well as exo-crines.Hormones are chemical messengers secreted by cell or gland. These messengers are sent out from one part of the body to affect cells in other parts of the body. Hormones are often released directly into the bloodstream, Exocrine, but they may also be secreted into ducts, Endocrine. Hormones can have a wide range of effects on the body. They can cause mood swings, regulate the metabolism, control the reproductive cycle, induce hunger and cravings, stimulate or inhibit growth and prepare the body for changes such as puberty, childbirth or menopause. Hormone signals also play a major role in homeostasis, or the control and regulation of the body's internal environment.
And the juices that you have mentioned are basically enzymes that help in food degradation and digestion. While hormones activate their actions by stimulation

The main glands and organs of the endocrine system include:
Pituitary gland – is inside the brain. It oversees the other glands and keeps hormone levels in check. It can bring about a change in hormone production somewhere else in the system by releasing its own ‘stimulating’ hormones. The pituitary gland is also connected to the nervous system through part of the brain called the hypothalamus. The hormones released by the pituitary gland are gonadotropins (LH and FSH), growth hormone (GH), thyroid stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), prolactin, antidiuretic hormone and oxytocin.
Thyroid gland – sits in the neck at the front of the windpipe. It releases thyroid hormone (T4 and T3) which is required for metabolism and body homeostasis. It is controlled by TSH which is produced by the pituitary gland through a feed-back loop.
Parathyroid gland – there are usually four parathyroid glands which lie alongside the thyroid gland. The parathyroid gland is involved in calcium, phosphate and vitamin D regulation.
