• They realease the parathyroid hormone that helps in
regulating the level of calcium in blood along with another
hormone produced by thyroid called
as calcitinin.

10. 5. ADRENAL GLANDS
• These are located on the top of each kidney and are made of two
parts.
• The outer part called adrenal cortex produces hormones called
corticosteroids which regulate the body’s metamolism, the balance
