Why is a release of endotoxin into the bloodstream potentially deadly?

A release of endotoxin into the bloodstream can be deadly because it triggers a severe immune response known as septic shock. Endotoxins, which are components of the outer membrane of Gram-negative bacteria, can lead to widespread inflammation, vasodilation, and increased vascular permeability. This can result in a drastic drop in blood pressure, organ failure, and, ultimately, death if not promptly treated. The body's reaction to endotoxins can overwhelm normal physiological processes, leading to a life-threatening condition.
