ENDOCRINE SYSTEM
Endocrine System…. POOJA SAHARAN, M.Sc NSG I YR. M.M C.O.N, MULLANA
• System of ductless glands
• Regulates body functions via
hormones secreted into the
bloodstream.
Endocrine System…. POOJA SAHARAN, M.Sc NSG I YR. M.M C.O.N,
Mechanisms of hormone release
(a) Humoral: in response to changing levels of ions
or nutrients in the blood
(b) Neural: stimulation by nerves
(c) Hormonal: stimulation received from other
hormones
