Snakes have special glands and teeth designed to inject venom into their prey. The venom is a fluid secreted by snakes through their fangs. It is highly modified saliva containing several enzymes that attack the nervous system, blood and other tissues of the prey. Some species spit venom which helps the snake to immobilize and digest its prey. Some proteins in snake venom have specific effects on certain biological functions such as blood coagulation, regulation of blood pressure, are used in medical diagnosis and for preparing useful drugs.
