Snake venoms are mixtures of enzymes and peptides which exert toxicological effects by targeting their substrates or receptors upon envenomation. Snake venom proteins widely affect vascular system including circulating blood cells, coagulation factors, and vascular wall components.

It involves non-specific responses to pathogens that have invaded the internal environment of the organism. The second line of defence involves specialist cells and white blood cells such as phagotcytes, macrophages, neutrophils, natural killer cells, dendritic cells, complement proteins and mast cells.

After doing radiographs, experts found that the two-headed snake has several other unique features. The snake has two heads but one heart and one set of lungs. Both heads appeared to have venom, according to Kleopfer. Surviving as a two-headed snake in the wild is tough.

Hi Ritika, In coelenterates, specialised cells called cnidoblasts are present, which contain stinging cell organelles called nematocysts. Nematocysts help to paralyse or hold the prey by injecting poison present within it.

According to biologists, the term venomous is applied to organisms that bite (or sting) to inject their toxins, whereas the term poisonous applies to organisms that unload toxins when you eat them. This means that very few snakes are truly poisonous. ... Along with snakes, dangerous spiders are also generally venomous.

Primates (humans and monkeys) appear to be most susceptible, along with guinea pigs and mice. The spider's fangs are bigger than those of a brown snake (which are admittedly small at about 1 cm). The fangs (or chelicerae) are also very sharp and strong. They are allegedly able to pierce a fingernail and shoe leather.

Snake venom is a mixture of bioactive proteins and polypeptides, produced and stored in a highly specialized venom gland. After their administration through a bite, these proteins and polypeptides function as toxins and attack various physiological systems, often leading to death and debilitation of the prey or victim.

There are two types of B cells: Plasma B cells secrete antibodies which effect the destruction of antigens by binding to them and making them easier targets for phagocytes.

Two important types of toxins are exotoxins and endotoxins. ... In response to toxins, the body produces special antibodies called antitoxins, which unite with and neutralize the toxins, providing defense against disease. It is possible to immunize against the effects of exotoxins by injecting toxoids into individuals.

The venomous bite of a rattlesnake evolved as a tool for hunting and killing prey. The venom not only kills but also begins the digestive process by breaking down the tissue with hemotoxic components. The hollow fangs of a rattlesnake unfold from the roof of the snake's mouth when it strikes its victim.

"Adult snakes are as dangerous, or more dangerous, than a young snake," Steen said. "Adult snakes can have more venom than juveniles." And not all bites are the same. "Any snake bite can vary greatly in the amount of venom injected," Beane said.

Snake venom may be 'drug source' Venomous reptiles may provide a good source for new drugs for human diseases, researchers in Liverpool say. Venom has already been used to create drugs, but the chemicals in it are often too deadly for human consumption.

The adder is the UK's only venomous snake, but its poison is generally of little danger to humans: an adder bite can be very painful and cause a nasty inflammation, but is really only dangerous to the very young, ill or old.

alterna) will consume other snakes from time to time. Though specific data about their level of immunity to native pit vipers is lacking, it is likely that most exhibit some immunity to rattlesnake venom and may consume rattlesnakes.

Rattlesnake Venom and Bite The venomous bite of a rattlesnake evolved as a tool for hunting and killing prey. The venom not only kills but also begins the digestive process by breaking down the tissue with hemotoxic components. ... The venom is injected through the fangs which puncture the victim's skin.
