Testosterone primarily acts on various target organs and tissues, including the testes, prostate gland, muscles, and bones. It plays a crucial role in the development of male reproductive tissues, the maintenance of muscle mass, and the promotion of bone density. Additionally, testosterone influences the brain, affecting mood, cognition, and libido.
Prolactin releasing factor

testosterone (tĕstŏs`tərōn), principal androgen, or male sex hormone hormone, secretory substance carried from one gland or organ of the body via the bloodstream to more or less specific tissues, where it exerts some influence upon the metabolism of the target tissue.
when the chemicals arrive in the right places, the target tissues, they start to do their work. a group of cells that have receptors embedded in the plasma membrane that are complementary in shape to specific hormone molecules. Only these cells will respond to that specific hormone.
The insulin and glucagon are secrete by the pancreas. Glucagon mainly acts upon the liver. Insulin acts in general upon all cells. Both also act upon the adipose tissue respectively stimulating (glucagon) and inhibiting (insulin) the use of fatty acids in the energetic metabolism (an alternate path of the energetic metabolism is activated when there is shortage of glucose).
Addison's disease is a condition in which the adrenal glands do not produce enough hormones for a person to maintain normal body function. There are several different types of Addison's disease depending upon how many hormones are deficient. Treatment is based upon oral supplementation of the missing or deficient hormones for the remainder of the patient's life. However, there may be researchers working on stem cell, organ transplant or medical device implants as an alternative to popping pills every day.
The level of organization from atom to organism is as follows: atom, molecule, organelle, cell, tissue, organ, organ system, organism. Each level builds upon the previous one to create more complex structures and functions within living organisms.
This is dependent upon the persons own perspective of organ donations.
The levels of organization in the living world are: atoms, molecules, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere. These levels represent a hierarchy of complexity, with each level building upon the one before it to create a functional living organism.
Australian research has proven that emu breeding season is dependent upon the length of the day. The amount of daylight directly influences the production of reproductive hormones. As the number of daylight hours decrease, amounts of luteinizing hormone and testosterone in male emus increases, and after about three and a half months of shortening days, concentration of prolactin increases. This, in turn, results in a decrease of the luteinizing and testosterone until the male stops breeding. Corresponding to these times, the female emu's hormones start to stimulate egg production and make her more interested in the male.
Hormones are chemicals in the body that do all sorts of things for you. They regulate growth, reproductive systems, metabolism and more! When people think of hormones, they think of sexual hormones...but there are LOTS of different types of hormones that are constantly moving around your body! That dose not answer the question^
