Mini Lesson: Endocrine System
System made of ______________ that secrete hormones/chemicals to help control activities
in the body.
_________________________________ is the process by which an organism’s internal
environment is kept stable even though there are changes in the external environment.
Humans always have an internal temperature of _________________. The endocrine system
helps regulate our body’s internal balance.
Structure
Hypothalmus
Function
Part of the ______________________ that works to keep the body in
balance, homeostasis.
Main __________________ in the endocrine system. They release
hormones that control activities in the body to maintain balance.
Glands
Pituitary Gland releases a chemical that tells your body when to and
how much to grow. It also sends a chemical to tell your body to stop
growing.
___________________________ that causes changes in the body.
Hormone
Insulin is released in Pancreas. It helps glucose, a type of sugar,
enter the cells so it can be used for energy or stored for later.
Some Endocrine Glands
____________________ Gland – creates
hormones that affect our growth and
other organs.
Thyroid Gland – increases the rate
at which you use energy.
Parathyroid Gland – (behind the
thyroid) regulates calcium levels in
the blood.
Thymus Gland – regulates the
immune system, which helps your
body fight disease.
Adrenal Glands – helps the body
respond to danger.
______________________ – regulates
blood sugar levels
Ovaries – (in females) produce
hormones needed for reproduction.
Testes – (in males) produce
hormones needed for reproduction.
The pituitary gland releases the hormones that affect your growth. Infer what may happen if this gland has a
genetic mutation that always releases hormones telling your body and some organs to grow. What would
happen to you?

levels in the body. Infer what may happen if the pancreas was unable to produce insulin. What would happen to
you?

Brainpop: Endocrine System
The _______________________________system is in charge of making sure that your body’s many functions
are coordinated. It’s made up groupings of cells called glands. There are eight major endocrine glands: the
pituitary gland, the thyroid gland, the adrenal glands, the pineal gland, the pancreas, the thymus, the
parathyroids, the ovaries in women, and the testes in men.
_______________________________ are responsible for regulating your metabolism, mood, growth, and
organ function. A part of your brain called the hypothalamus is critical to your endocrine system. It monitors
your body and sends the information to your pituitary gland. The pituitary gland is attached to the
hypothalamus, and it’s like the king of the endocrine system. It sends out its own chemical messages and rules
the actions of most of the other major endocrine glands.
The _______________________________releases hormones that control how fast your body’s cells burn
energy. That’s important, because it affects how other parts of you may grow and develop. The parathyroid
glands keep the level of calcium in your blood at a certain level. If, say, your blood has too much or too little
calcium, your nerves and muscles don’t work right.
The _______________________________glands regulate your response to stress. Right, they release the
hormone adrenaline in dangerous or exciting situations. It gives you a quick burst of strength and speed. The
adrenal glands are also involved with your body’s regulation of salt, and its sexual development during puberty.
The function of the _______________________________gland isn’t fully understood yet. All we know is it
secretes a hormone called melatonin that’s thought to influence our sleep cycle, metabolism, and sexual
development. The _______________________________secretes the hormone insulin, which regulates your
blood sugar.
You’ve probably heard of type 1 diabetes – that happens when the pancreas can’t produce enough insulin to
control your blood sugar. The thymus helps your body fight off infections. It’s a key player in the production of
T cells, which identify and kill germs in your blood. .
On one side we’ve got the _______________________________and cells that produce hormones. And the
other side we’ve got cells and tissues that respond to the hormones. When glands secrete hormones into the
bloodstream, the hormones travel to a target cell or target tissue. When the target’s receptors get their chemical
message, they go to work carrying out their function.
Well, the endocrine system works in _______________________________. It produces hormones, and the
hormones do their job, causing many different things to happen in many different types of cells. Think about
how you suddenly start growing in your teen years.
When it’s time for a _______________________________spurt, the pituitary gland sends out a growth
hormone that tells your cells, “It’s time to grow up!” Start dividing! Your adrenal glands and sexual glands also
contribute. When your _______________________________is finished growing, your cells will produce
chemicals that stop those growth hormones from being released. That’s why you stop growing. This is called
negative feedback, and it’s how most hormone production is regulated.

Homework #74 – Due Tomorrow
Ms. Lopez 646-477-2658 ** [email protected] ** https://dph6science.wikispaces.com/
The Endocrine System By Jennifer Kenny
When you think of a system in the body that responds to stimuli, you think of the nervous system. In its
own way, the endocrine system responds as well. Instead of electrical messages, though, it sends
messages using chemicals.
1. Name 1 similarity between the nervous and endocrine system.
___________________________________________________________________
___________________________________________________________________
___________________________________________________________________
The endocrine system controls body functions with the help of glands that release chemicals. A gland
is a group of cells that produce these chemicals. These special chemicals are called hormones.
Hormones are released into the bloodstream in order to be carried to other places in the body. Other
glands have different jobs as well. Your pituitary gland works with skeletal growth, amount of water
in the blood, and the birth process. The thyroid gland increases the rate at which you use energy. The
parathyroid glands regulate calcium levels. The thymus gland controls the immune system. The
pancreas controls levels of blood sugar. The ovaries (in women) and the testes (in men) are involved
in reproduction.
2. How do the parathyroid glands affect the skeletal system?
___________________________________________________________________
___________________________________________________________________
___________________________________________________________________
Endocrine glands know when to start and stop releasing hormones because of feed back controls. These
feedback controls let the glands know when to stop sending a particular hormone. For example, the
pancreas is able to know how much insulin your body needs and, therefore, can stop sending it when
blood sugar returns to normal and more insulin is not necessary. Sometimes, though, hormones can
become imbalanced. For example, if a person's pancreas can't make enough insulin, that individual is
considered diabetic and may need insulin shots. If a child's pituitary gland doesn't work properly, a
child may be very short or very tall as a result. If a person's thyroid gland doesn't work correctly, the
consequence might be that the person is very tired or gains weight. Properly working glands are,
therefore, essential to good health.
