What is the function of hormones?

Answer 1

Hormones are a chemical control system within an organism (plants and animals). Their function is to control the physiological activities within the body, maintaining its proper operation.

In humans, glands (such as the endocrine glands) secrete hormones to regulate cellular activities, and control the health and operation of various organs in the body.
Hormones are like messengers in your body that give orders to your cells to do particular things. They are chemicals that are manufactured by glands and released into the bloodstream, sort of holding a sign up with a type of cell's name on it (like a limo driver at the airport waiting to pick up a client.) Most cells ignore the hormone, but when it comes across the right one its chemical "message" is read and the cell starts to do what it has been told. This message could be a lot of different things, but generally it is meant to keep the body functioning and in balance.

Here are some things that hormones do for the body. Remember, though, they are only the "messengers" that start the cells into action. They go out into the body when told to by a higher power (the gland) and it's the cell that actually does the work.

• make people grow or stop growing,
• make people feel happy or sad,
• speed up or slow down the metabolism,
• starting puberty,
• regulating your fighting, mating, and fleeing instincts.

In general, hormones are chemical messengers in the body and is how different parts of the body communicate with each other. To get more specific than that, it really depends on what hormones you're talking about. Some help with other hormones, some give you sensations (make you tired, hungry, etc.), and some help with puberty. You have to be more specific; there are LOTS of things that hormones do. Control: they control cellular activities. Control: they control cellular activities.
There are literally dozens of hormones released by the endocrine system. Their functions are too diverse to enumerate here, but in general they all play a large part in the regulation of body functions. These include growth and development, immune system function, responses to stress and other emotions, basal metabolic rate, pair bonding, and sexual reproduction, to name a few.
