All organ systems require a balance of cell division and apoptosis during development, growth, and repair to maintain tissue structure and function.

The endocrine and immune systems are important regulators for cell populations.
00:14
The endocrine system delivers steroids and growth hormones that send survival signals to specific tissues so that apoptosis is prevented.
00:20
Additionally, the endocrine system delivers some hormones that work to induce apoptosis under some physiological conditions.
00:25
The endocrine functions of the pancreas and liver coordinate efforts to maintain normal blood glucose levels.
00:30
When pancreatic cells detect low blood glucose levels
00:32
the pancreas synthesizes and secretes the hormone glucagon.
00:37
Glucagon causes the liver to convert the polymerized sugar glycogen into glucose through a process known as glycogenolysis.
00:41
If pancreatic cells detect high blood glucose levels, the pancreas synthesizes and releases the hormone insulin.
00:45
Insulin causes polymerization of glucose into glycogen, which is then stored in the liver through a process known as glycogenesis.
