What is Chemical Control and Integration?

Chemical control and integration refer to the regulation of body functions through hormones secreted by endocrine glands. These glands release hormones directly into the blood, which then act on target organs. Examples include:

• Insulin from the pancreas, which regulates blood sugar levels.

• Thyroxine from the thyroid gland, which controls metabolism.

• Adrenaline from the adrenal glands, which helps in fight-or-flight response.
