Hormones

Hormones

Hormones are special natural juices that our bodies make to control how we work.

Hormones are naturally occurring chemical substances in the body.

These are just natural chemicals inside you that help your body function well.

Special parts of the body called glands produce these chemicals without using any pipes or tubes.

They are produced and secreted by specialized cells known as endocrine glands or ductless glands.

This means the glands just pour the hormones directly into the blood because they have no ducts.

Hormones are like messengers that carry information from one place to another.

These hormones act as chemical messengers.

Think of them like a postman carrying a letter to a specific house.

The body pours these chemicals into the blood so they can reach far places.

They are released into the bloodstream from one part of the body to influence cells in other areas.

The blood carries the message from where it is made to the place that needs to hear it.

Once the hormone is in the blood, it travels until it finds the specific part of the body it needs to work on.

Once in the bloodstream, hormones travel to their target organs to exert their effects.

This means every hormone has a particular organ it is supposed to talk to.

Hormones can make things happen faster or make them go slower inside the body.

These effects can either speed up or slow down biological reactions within the body.

They act like a remote control that can increase or decrease the speed of your body's work.

Hormones do many different jobs to keep the body running correctly.

Hormones can have a wide range of effects on various bodily functions.

They handle many different tasks that keep you healthy and alive.

For instance, they can change how you feel, how you digest food, or how you grow.

For example, they can cause mood swings, regulate metabolism, control the reproductive cycle, induce hunger and cravings, and stimulate or inhibit growth.

This means they control everything from your hunger to how tall you will become.

Hormones also help the body get ready for big life stages like growing into an adult or having a baby.

Hormones also prepare the body for significant changes such as puberty, childbirth, or menopause.

They are the reason boys start growing beards and girls start seeing their periods.

The body only needs a tiny drop of these chemicals to keep everything balanced and growing well.

Typically, hormones are needed in small amounts to maintain homeostasis, growth, and development.

Even a small amount is enough to keep your internal body temperature and systems steady.

When a hormone finishes its job, it goes to the liver to be switched off.

After they have performed their functions, hormones become inactive in the liver.

The liver breaks them down so they do not keep working when they are not needed.

After the liver finishes with them, the body throws them away when you use the toilet.

They are then excreted from the body through urine.

This means you pee out the remains of the hormones your body has used up.

Important Animal Hormones

There are several main hormones made by different glands in animals and humans.

Pituitary hormones

Thyroid hormones

Parathyroid hormones

Pancreatic hormones

Adrenal hormones

Reproductive hormones

Some basic animal hormones secreted by different glands include pituitary hormones, thyroid hormones, parathyroid hormones, pancreatic hormones, adrenal hormones, and reproductive hormones.

These are the different groups of chemical messengers found in our bodies.
