Summary Introduction
Introduction:
Endocrine cells secrete hormones into the extracellular fluids, which are the signaling molecules. The secreted hormones reach target cells through the bloodstream. Hormones bind only to specific cells based on the corresponding receptors and they act through chemical signals. They maintain homeostasis and regulate growth, development, blood pressure,
