Answer 1

Endocrine glands are glands that secrete hormones directly into the bloodstream, which regulate various physiological functions in the body.
Four major endocrine glands are:
Thyroid Gland: Secretes thyroxine, which regulates metabolism.
Pituitary Gland: Secretes growth hormone, which regulates growth and development.
Adrenal Glands: Secrete adrenaline, which helps in the body’s fight-or-flight response.
Pancreas: Secretes insulin, which regulates blood sugar levels.
