To determine: Whether the statement ‘Intercellular communication through extracellular fluid is a characteristic of paracrines’ is true or false.
Introduction: The endocrine system is the chemical signaling system that uses blood vessels as information channels. The endocrine glands are ductless organs located within the organ systems and contain groups of endocrine cells that secrete their hormones directly into their surroundings.
