Prostaglandins are best described as?

Explanation:
Prostaglandins are lipid-derived signaling molecules that act locally as paracrine or autocrine mediators. They’re produced from arachidonic acid in many tissues and have effects confined to the site of synthesis, with very short half-lives, rather than traveling through the bloodstream to distant targets. This local, short-range action distinguishes prostaglandins from classic endocrine hormones like thyroid hormones, insulin, or adrenaline, which are produced by glands and act systemically. So the best description is that prostaglandins themselves are prostaglandins—part of the local eicosanoid signaling system involved in inflammation, pain, fever, and regulation of blood flow and clotting.
