The endocrine system maintains homeostasis in the body through glands that secrete hormones directly into the bloodstream. The major glands include the pituitary, thyroid, parathyroid, adrenal glands, pancreas and gonads. The pituitary gland is called the "master gland" as it controls many other glands by producing hormones like ACTH, TSH, FSH, LH and growth hormone. These hormones target various organs and tissues to regulate processes like metabolism, growth and development, sexual function, mood, and other bodily functions.

2. THE ENDOCRINE SYSTEM
The nervous system works closely with the
endocrine system, another biological system
governing man’s behaviour.
The endocrine system or ductless gland is
involved with the process of maintaining the
biochemical equilibrium in the body or
homeostasis.
The ductless glands are located in the
different areas of the body.The glands
secrete chemical, excitatory substance called
hormones, which go directly into the
bloodstream.

4. WHAT ARE HORMONES?
Hormones are chemical messengers that are secreted directly into
the blood, which carries them to organs and tissues of the body to
exert their functions.There are many types of hormones that act on
different aspects of bodily functions and processes. Some of these
include:
Development and growth
Metabolism of food items
Sexual function and reproductive growth and health
Cognitive function and mood
Maintenance of body temperature and thirst

5. PITUITARY GLAND
“The Master Gland”
Secretes
Adrenocorticotropic
hormone (ACTH) which
stimulates the adrenal
cortex.

6. ANTERIOR LOBE
Thyrotropic hormone : : stimulates the
thyroid gland
Gonadotropin : Follicle stimulating
hormone : stimulates ovarian follicle
In the female reproductive system, an
ovarian follicle is a fluid-filled sac that
contains an immature egg, or oocyte.
These follicles are found in the ovaries.
During ovulation, a mature egg is
released from a follicle.

7. ANTERIOR LOBE
Luteinizing hormone :
stimulates the sex glands
Growth hormone
(Somatotropin): promotes
growth in all parts of the body
Prolactin : stimulates mammary
gland to produce milk

8. THYROID GLAND
Thyroxine : regulates basal
metabolism.
Basal metabolism is the
minimum amount of energy
required to maintain vital
functions in an organism at
complete rest, measured by
the basal metabolic rate in a
fasting individual.

9. PARATHYROID GLAND
Parathormone : regulates
calcium and phosphorus
level in the blood

10. ISLETS OF LANGERHANS
Insulin : regulates sugar
level in the blood

11. ADRENAL GLANDS
Cortisol : released during
stress
Cortin : regulates
development of adult
sexual characteristics
Adrenaline : affects
emotional response

12. GONAD : TESTES
Testosterone : promotes
adult male secondary
sexual characteristics

13. GONAD : OVARIES
Progesterone : promotes
adult female primary
sexual characteristics
Estrogen : promotes adult
female secondary sexual
characteristics
