Question

Quizplus · Accepted Answer

Prostaglandins act locally, meaning they are produced and released in the vicinity of the cells that they affect, rather than being distributed by the bloodstream like other hormones. They can cause various effects such as inflammation, fever, and the contraction or relaxation of smooth muscle. They also play a role in the sensation of pain. Prostaglandins are not proteins, but rather lipid molecules.
