A hemotoxin, also spelled hemotoxin or haemotoxin, is a type of toxin that affects the blood and circulatory system of organisms. It is specifically designed to target and damage the blood cells, blood vessels, and related components. Hemotoxins are commonly found in the venom of certain animals, such as snakes, spiders, and some marine creatures like jellyfish.
When a hemotoxic venom is injected into the body, it can disrupt the normal functioning of the circulatory system. The toxin may cause the destruction of red blood cells, interfere with blood clotting mechanisms, or damage the walls of blood vessels, leading to internal bleeding. Some hemotoxins also have the ability to affect platelets, which are involved in blood clotting, thereby increasing the risk of uncontrolled bleeding.
The effects of hemotoxins vary depending on the specific toxin and the organism it targets. The severity of symptoms can range from mild, localized effects to more severe systemic reactions. Common symptoms of envenomation by a hemotoxic venom include pain, swelling, bruising, tissue damage, bleeding from the site of the bite or sting, and in severe cases, organ failure or even death.
