Describe how the endocrine system provides a communication pathway
What will be an ideal response?
ANSWER:
?The endocrine system is a chemical system of communication that relies on the action of specialized organs called endocrine glands that are located throughout the body. When stimulated, endocrine glands release chemicals called hormones into the bloodstream. These hormones circulate through the bloodstream until they reach other organs in the body. Our internal organs are equipped with special receptor sites to accept these hormones. The endocrine system is considerably slower than the nervous system in relaying messages because it relies on blood circulating through the veins and arteries of the cardiovascular system to transport hormones throughout the body. The stimulation created by hormones, however, tends to last longer than the stimulation caused by action potentials at the synapse.
