Endocrine Pancreas Hormones

The two hormones secreted from the endocrine pancreas are insulin and glucagon.
Insulin and glucagon have opposite effects on blood glucose levels.

Insulin and Glucagon Target Organs

The major target organs for insulin are the liver, muscle, and adipose tissue.
The major target organs for glucagon are the liver and adipose tissue.

Insulin/Glucagon Ratio

The insulin/glucagon (I/G) ratio plays a crucial role in regulating body metabolism.
An imbalance in the I/G ratio can lead to metabolic disorders.

Diseases Caused by Insulin and Glucagon Imbalance

Hypoglycemia is caused by an over-secretion of insulin.
Diabetes is caused by a deficiency of insulin or insensitivity to insulin.

Effects of Physical Activity on Blood Glucose

Regular physical activity helps to decrease blood glucose levels.
Physical activity increases the body's sensitivity to insulin.

Hormonal Functions

Glucagon promotes the breakdown of glycogen into glucose in the liver.
Insulin promotes the uptake of glucose by cells, thereby decreasing blood glucose levels.
Somatostatin inhibits the secretion of both insulin and glucagon.
Cholecystokinin (CCK) has a role in regulating pancreatic exocrine secretion and gallbladder contraction.
Insulin is primarily responsible for the uptake and storage of glucose in adipose tissue.
