Endocrine System Essential Questions

Name:_______________________ Date:__________ Lesson Title: Endocrine System

Essential Questions: How do the parts of the endocrine system work together to

protect and beneﬁt the body? How does the endocrine system operate as a

closed loop system?

Letter:

The endocrine system is in charge of processes that happen slowly, such as the growth

of cells. The glands and hormones of the endocrine system inﬂuence almost every cell

and organ in the body.

Hormones are the bodyʼs chemical messenger. They send important information from

one set of cells to another. Each hormone only affects cells that are programmed to

receive a speciﬁc hormoneʼs message. Glands are groups of cells that produce

chemical products for our body to use. For example, salivary glands produce saliva.

Once hormone levels reach a certain amount, endocrine system glands will produce

less of a speciﬁc hormone. Endocrine glands are told to produce less of a hormone by

substances in the blood or by the very hormone the gland is about to stop producing a

large amount of. This hormone “turnoff” process is called a negative feedback or a

closed loop system.

Activity: Create a simple T-Chart listing fast and slow body processes (for example,

growth is a slow process; breathing is a fast process).
