7. Endocrine System Flashcards
Do not have a duct system and release their secretions or hormones directly into the bloodstream
Endocrine Glands
Have ducts that allow the cells to secrete their products.
Exocrine glands
- The glands which function as both exocrine
gland and endocrine gland. - Thus, these glands have dual role.
* Pancreas
* Gonads
* Stomach
* Intestines
Heterocrine (Composite or mixed glands)

- Found at the base of the brain (sella turcica),
in line with the top of the nose. - Acts as the body’s ‘master gland’.
- It tells other glands in your body what to do.

- Make hormone insulin
Pancreatic islets (Islets of Langerhans)
What is this:

What is the location of the Pineal Gland (Epiphysis cerebri)?
Posterior aspect of the cranial fossa in the brain.
__________ are chemical substances that act like
messenger molecules in the body.
Hormones
What is this:
After being made in one part of the body, they travel to other parts of the body where they help control how cells and organs do their work
