Practice and Revision - The Endocrine System
Let us practise and revise what we learned about the endocrine system. The endocrine system uses hormones secreted by glands to regulate bod
Core concept
The pituitary gland, often called the 'master gland,' controls other endocrine glands and secretes hormones like growth hormone.
How it works
The thyroid gland secretes thyroxine, regulating metabolic rate, with both hypo- and hyper-thyroidism causing health issues.
Why it matters
The pancreas secretes insulin and glucagon, regulating blood sugar levels, with insulin deficiency causing diabetes.
Key detail
The adrenal glands secrete adrenaline, preparing the body for 'fight or flight' responses during stress or emergency situations.
