| Difference between exocrine and endocrine glands? |
|
Definition
-Exocrine uses a duct to secrete (like sweat glands)
-Endocrine is ductless and secretes hormones |

| What are merocrine, apocrine, and holocrine secretion? |
|
Definition
-Merocrine is exocytosis where the vacuole inside the cell fuses and releases contents to outside (most common)
-Apocrine is discharge of free vesicles
-Holocrine is secretion via cell lysis (an example is in simple branched acinar glands around hair shaft where sebum is released) |
