endocrine system 

The endocrine system is made up of a series of glands that produce chemicals called hormones to regulate the body.

Hormones regulate many functions of an organism, including mood, growth and development, tissue function, and metabolism.

Typical endocrine glands include the pituitary, thyroid, adrenal, pineal, hypothalamus, parathyroid, thymus, adreanal, pancreas, testes in men and ovaries in women.
The endocrine system is a bodily system that consists of the endocrine glands and functions to regulate body activities.

endocrinology 

The study of fat people, hairy women and midgets.
I went to Paris and started studying all the hairy women and thought I could open an Endocrinology clinic on the spot.

Endocrine Technologies

The specialized hardware and software interfacing directly with endocrine organs or functions. Think beyond wearables to closed-loop "artificial pancreas" systems, transcranial magnetic stimulation devices designed to modulate hypothalamic function, or microfluidic chips that culture endocrine tissues for drug testing. These are the precision instruments for interacting with the body's chemical command center.
Example: "The new endocrine technology for astronauts is a wrist-worn sonogenic device. It uses targeted ultrasound pulses to gently stimulate the parathyroid gland, helping maintain calcium balance in zero-G without drugs, literally using sound waves to give a gland polite instructions."

Endocrine Engineering

The applied discipline of designing biological or synthetic systems to correct, enhance, or replace endocrine function. This includes tissue engineering of pancreatic islet cells for diabetes, creating artificial thyroid glands, or developing "smart" hydrogels that release growth hormones in response to local inflammation. It's biomedical engineering with a focus on the body's master regulatory network.
Example: "The lab's breakthrough in endocrine engineering was a bio-artificial adrenal capsule. For patients with Addison's disease, it sensed blood cortisol levels in real-time and secreted precise replacement doses, mimicking the lost feedback loop perfectly. It was a tiny, implanted organ grown from the patient's own cells."

Endocrine Sciences

The foundational biological science dedicated to the endocrine system—its anatomy, the synthesis and secretion of hormones, their transport, receptor interactions, and the physiological effects they produce. It is the core discipline that provides the detailed map of chemical signaling which applied fields like hormonal engineering and technology then seek to navigate and modify.
*Example: "Endocrine Sciences 101 was a deep dive: from the gene expression for insulin in pancreatic beta-cells, to the negative feedback loop of the HPA axis, to how a malfunctioning pituitary can make a grown man lactate. It was less about 'what hormones do' and more about 'how this unbelievably precise chemical mail system works.'"*

Endocrine Thermodynamics

A more specific subset of Hormonal Thermodynamics, focusing explicitly on the entire endocrine system as a distributed, self-regulating thermodynamic engine. It models how glands like the thyroid, adrenals, and pancreas work in concert to manage the body's energy throughput (metabolic rate), heat production (thermogenesis), and resource allocation under stress, applying principles of feedback control and energy dissipation to endocrine networks.
Example: "His paper on Endocrine Thermodynamics described the body under chronic stress as a 'heat engine stuck in a high-idle state.' The adrenal cortex and thyroid were in a positive feedback loop, burning fuel to produce stress hormones and warmth but accomplishing no useful external work, just wearing out the machinery."
