Endocrine Glands Group of :
seus
specialised to screte hormones into the blood
Exocrine Glands Secrete :
other molecules via ducts
Pituitary Gland Produces hormones
·
growth
:
·
Thyroid Gland Produces thyroxine :
to control metabolism
·
Adrenal Gland Produces adrenaline :
·
Testis :
Produces testosterone
· Ovaries Produce
destrogen
:
·Pancreas Produces :
insulin
·
Produces thymosin for production of
Thymus the white blood cens
:
·Pineal Gland Produces :
melatonin
Hormones blood and bond to
target sell
Chemical
messengers that travel in the receptors
:
Steroid hormones Lipid soluble pass the membrane and bond
through to
cytoplasm receptors
·
:
,
·
Non-steroid :
Hydrophilic so bond to cell surface receptors - release of CAMP

Adrenal Gland :
Adrenal Cortex Produces hormones :
that are essential for life
Adrenal medulla Produces :
non-essential hormones
Glucocorticoids
E
:
Cortisol
Regulates metabolism in to stress
-
response
:
- Corticosterone Regulates immune response/inflammation
· :
mineralocorticoids :
Aldosterone Controls blood :
pressure by balancing salt/water
Androgens
:
small amounts of sex hormone
Adrenaline Increases :
heart rate and
produces lots of glucose
Noradrenaline Works with adrenaline to :
respond to stress
