Snakes have special organs called venom glands which are connected to venom ducts which carry the venom to their fangs so that when a snake bites the venom ducts quickly carry venom to their fangs.
There are two general classifications of snake venom:1.) Neurotoxins that attack the nervous system resulting in paralysis of the respiratory system. Cobras, mambas, boomslangs and coral snakes are examples.
2.) Cytotoxins which attack tissues, especially the blood. Some cause the blood to lose the ability to coagulate while others cause coagulation. Some attack heart tissues and other muscle tissues. Most vipers, such as rattlesnakes, have cytotoxins. Some cytotoxins are basically digestive enzymes which cause massive tissue damage by 'digesting' any tissue it contacts.
The Mojave rattlesnake, especially those found in southern Arizona, contain both neurotoxic and cytotoxic components making it a particularly dangerous snake.
What the venom does is digest the flesh and internal organs of the victim and, if the area is left untreated, the result is amputation.
toxins in the venom travel up the the bloodstream and poison the heart.
yes i had a friend who died from a spider bite she was only 25
it can kill a human in about an hour or less
You would first have to check the size of the spider. If it is a huge spider, it is obiously a tarantula. (Depending on location, very unlikely that it is a tarantula) If it is small, check for violin-shaped markings on the abdomen (the 'violin' markings of the brown recluse are on the cephalothorax where the legs are attached). If there are, the spider is a brown recluse. Depending on location, size, body shape, coloration, web or not, and where in your house, it could be any number of harmless spiders. A more detailed description would yield more information. ---------------------------- If it has a violin on it's back, kill it immediately! It's a Brown Recluse (A.K.A. The Violin Spider). The Brown Recluse has an acid-like venom that melts skin tissue, muscle & fat. If it's fuzzy, kind of large, & somewhat bright, also kill it immediately. It's a Wolf Spider. Their venom isn't deadly, or nearly as toxic as the Violin Spider, but their bites are very painful, they swell, they itch, & in some cases, can make you nauseous.
If you're asking how many people die due to spider bites in a year, well... That completely depends on what part of the world. Some places there are zero, some between fifty and one hundred. 110
Tarantulas are known for their intricate funnel-shaped webs, but there are species of spider such as the Wolf Spider who's web is funnel shaped as well. More than likely the spider is not dangerous, but it depends on the species of the spider you're dealing with. A common spider in the pacific northwest that create a funnel like web are the hobo spider. It can not kill you but their venom is rather potent. It can dissolve the skin surrounding the bite if the bite is not treated correctly. They are large, and the hobo is larger than the brown, and the hobo is also more dangerous. In addition to greater size, it has greater speed and the venom is more potent ------------------------- The spider he's talking about is the Sydney Funnel-Web which can kill a human within 40 minutes of the time of the bite. & The Hobo spider is not the spider that dissolves skin, the Brown Recluse is the one that dissolves skin.

Unlike other species of spider, the brown recluse doesn't build a web to catch its food. It stalks its prey, sneaking up on it then uses its venom to paralyze and kill.
The two most famous and venomous are probably the Black Widow and Brown Recluse (or Violin Spider). Their venom is powerful and may be fatal if untreated.

Yes. If you suspect that your child has been bitten by a brown recluse spider, seek immediate medical attention.
It takes a brown recluse two whole weeks to kill a human
a black widow and a brown recluse. they both have an effect on human. tranulas dont kill us just put us in pain A spider's venom either kills or paralyzes the prey species.

The act of stinging does not kill the Brown Recluse the way stinging kills honeybees. However, the Brown Recluse typically bites humans in defense, so it's already in extremis -- it's not unusual for the spider to be discovered dead as a result of being crushed, after stinging.

Cowboy boots have pointed toes for a reason. Bug spray that's rated to kill spiders also works.
