Endocrine system 2: Structure
There are several endocrine glands in the body, the structure of which we will study.
The endocrine system provides the body with one of its two coordination and control mechanisms. This system secretes chemicals from glands into the blood that affect the function of target organs in the body. What are the chemicals called that are secreted by endocrine glands?

The endocrine system allows the body to respond to changes. Hormones change the function of their target organs. This might be to respond to an external stimulus, such as being frightened.
Getting a fright is one kind of stimulus. Other stimuli might be from internal changes in the body, for example a drop in blood sugar levels if you have not eaten for a while. In both situations the glands need to be instructed to respond. What might be the sources of this control?

The pituitary gland is the body's master gland. Where is it located?

Some of these target other glands to control how much hormone they secret in turn.
How do the hormones from the pituitary gland get to these other glands?
When a hormone from the pituitary gland reaches its target gland, what will it do to that gland?
