by a specific hormone
onthe targetorganhas receptors which detect the hormone can trigger a
response in cell
Types of Glands
a Exocrine have ducts secrete directly into target areas

Homones Usually inhibitprevent or stimulate
There are receptors that moniter hormonelevel provide feedback to brain
This allows the to monitor hormonelevel respond accordingly

If level of hormone to highto low negativefeedback will cause appropriate respo
to bring levels back to normal dHomeostasis mechanisms that help maintain a
constantIstable internal environment
