SNAKE BITE

Very few snakes, with the occasional exception of king cobras or black mambas act aggressively toward a human without provocation. Snakes are all meat eaters. They catch prey that includes insects, birds, small mammals, and other reptiles, sometimes other snakes. Some snakes grab prey with their teeth and then swallow it whole. Most snakes kill by constriction while only about 400 of 3,000 snake species worldwide inject venom Snake Bite

Snakes that inject venom use modified salivary glands. Venom is a modified form of saliva and probably evolved to aid in chemical digestion. Varying degrees of toxicity also make it useful in killing prey. During envenomation the venom passes from the venom gland through a duct into the snake’s fangs, and finally into its prey. Snake venom is a combination of numerous substances with varying effects. In simple terms, these proteins can be divided into 4 categories:

  1. Cytotoxins cause local tissue damage.
  2. Hemotoxins cause internal bleeding.
  3. Neurotoxins affect the nervous system.
  4. Cardiotoxins act directly on the heart.
