The pineal gland contains a number of peptides, including GnRH, TRH, and vasotocin, along with a number of important neurotransmitters such as somatostatin, norepinephrine, serotonin, and histamine but the most important hormone is the melatonin
There is little attention given to the Carotid Body but it is the smallest organ at the size of a grain of rice. The pineal gland--it's 8mm long in human bodies. It's located above the superior colliculus and behind and beneath the stria medullaris. It's also a part of the epithalamus. An organ is a complex structure formed by 2 or more tissues. If we use this definition, then a corpuscle of touch (Meissner's corpuscle) would be an organ and much, much smaller than the pineal gland. A corpuscle of touch consists of nerve endings (dendrites) and a connective tissue covering. Another candidate for the smallest organ would be a taste bud, but I think corpuscles of touch would be smaller. A more appropriate question might be, "What is the smallest organ that is part of the gross anatomy of the human body." The pineal gland might be the correct answer for this.
The type of exocrine gland you are referring to is a merocrine gland. Merocrine glands release their secretory products by exocytosis without losing any part of the cell. Examples include salivary glands and sweat glands.
The hormone responsible for regulating T cell development is called thymosin. Thymosin helps promote the maturation and differentiation of T cells in the thymus gland.
A gland is a cell or organ that secretes substances, such as hormones, enzymes, or other molecules, to be released into the bloodstream or surrounding tissues. Glands play a crucial role in maintaining physiological balance and regulating various bodily functions. Examples include the thyroid gland, adrenal glands, and pancreas.
The immune system. It regulates T cell development.
The pineal gland (also called the pineal body or epiphysis, is also called third eye) is a small endocrine (smallest)gland located in the brain. It is located near the center of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join.

A gland is a cell, group of cells, or organ producing a secretion.
The main function of the thyroid gland is to control cell metabolism.
The effector cell responds to a nerve impulse and can be either a muscle cell or a gland cell.
An adenocyte is a secretory cell of a gland.
By its cell address.
A function of the thyroid gland is the regulates calcium in blood
to produce egg cell
Robert Hooke was the first to identify the cell of a nucleus.
Gland cells are cells that release digestive enzymes into the gastro vascular system. Gland cells are also known as zymogen cells.
Given a good microscope I can identify all parts of an onion cell.
