Endocrine System: Glands
• Relatively slow-acting,
–uses chemicals called hormones.
• feedback system, produces
something that is sensed by
brain which ceases production
of the hormone. (homeostasis
again)
Endocrine System: Glands
• Pituitary: master gland.
–Sends hormones to control other
glands. Controlled by
hypothalamus.
–Also controls growth.
Endocrine System: Glands
• Thyroid: located in throat.
– Controls metabolism (speed in
which body processes).
– Extremes can create sluggishness
and obesity, or intense anxiety
and weight loss.
Endocrine System: Glands
• Adrenal: produces epinephrine
(adrenaline)
–to create fight or flight response.
– Cause increased body responses,
blood clotting.
Endocrine System: Glands
• Pancreas: controls blood sugar by
producing insulin that burns
glucose, (the real name of blood
sugar.)
Endocrine System: Glands
• Ovaries/Testes: Sex glands.
–Control secondary sex characteristics.
• Testes: androgen (testosterone).
• Ovaries: Estrogen.
