CHEMICAL
COORDINATION AND
INTEGRATION

, Introduction
 The human body relies on chemical
coordination to maintain homeostasis and
regulate various physiological processes. This
coordination is primarily executed through
hormones—non nutrient chemicals
acting as intercellular messengers
produced by endocrine glands in trace
amounts .They travel through the
bloodstream to target organs. The
endocrine system operates more slowly
than the nervous system, enabling it to
manage prolonged activities like growth,
metabolism, and reproductive functions. This
intricate system is essential for maintaining
internal balance despite external changes.

, Overview of the Endocrine System
 The endocrine system consists of several ductless glands
that secrete hormones directly into the bloodstream. These
hormones act on specific target cells or organs, influencing a
wide range of physiological functions. Major glands include:
 Pituitary Gland
 Thyroid Gland
 Parathyroid Glands
 Adrenal Glands
 Pancreas
 Gonads (Ovaries and Testes)
 Hypothalamus
 Thymus Gland
 Pineal Gland
 Organs of GI, Kidney and Heart
