1. Endocrine and Exocrine
A lesson on both of the systems and their functions

2. Lesson plan Walkthrough PowerPoint. Show and explain model.
Answer any questions.
Hand out and work on worksheet.

3. Exocrine System Glands that contain ducts.
Contain a glandular portion and a duct portion.
Three ways of secretion.

4. Ways of Secretion: Merocrine
Cells excrete their substances by exocytosis.
Membrane-bound secretory vesicles internal to the cell.
Example: Pancreatic acinar cells.

5. Ways of Secretion: Apocrine
Portion of the plasma membrane buds off the cell
Results in a secretory product that contains a variety of molecular components including those of the membrane.
Example: Mammary Gland

6. Ways of Secretion: Holocrine
The entire cell disintegrates to excrete its substance.
The secretory cell is released and it breaks apart.
This mode of secretion results in the most complex secretory product.

7. Endocrine System Hormone producing structures of the body.
Some, like the thyroid are large and obvious.
In lacking ducts, endocrine cells release their secretory products into the spaces around the cells.
Cell that product is headed towards is the target cell.

8. The Pancreas Serving as the Exocrine System:
The pancreas excretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food.
Serving as the Endocrine System:
The pancreas secretes the hormones insulin and glucagon to control blood sugar levels throughout the day.

9. Diseases included in major glands/organs
Pancreatic Cancer
A malignant neoplasm originating from transformed cells arising in tissues forming the pancreas.
Endocrine gland hyposecretion
Hyposecretion of hormones
Endocrine gland hypersecretion
Over production of hormones
Exocrine pancreatic insufficiency (EPI)
Caused by a degenerative disease of the pancreas.
