How does snake venom affect human body?

Depending on the type of snake, the amount of venom released and other factors, snake venom will bring various effects to the human body Different snakes produce different venoms Even the same snake contains different venom components because of its different geographical location This is also the reason why it is very important to identify the species of snake after being bitten and to deal with it properly There are three basic types of snake venom Hemotoxin is specially used to attack cardiovascular system; cytotoxin targets specific parts or muscle groups; neurotoxin attacks brain and nervous system Some vipers mix a variety of venoms to enhance their bite effectiveness, while others carry only one venom All snake venoms contain a complex mixture of proteins and enzymes If bitten by a venomous snake, the venom lowers blood pressure and promotes clotting The snake venom also attacks heart muscles in order to cause death Cytotoxin is specially designed to cause cell death, which is why many people need amputation after being bitten, because snake venom engulfs local tissues Many cytotoxins spread throughout the body, accelerating snake venom penetration by increasing muscle permeability The venom of nerve snake disturbs the function of brain and nervous system The snake venom can cause paralysis or muscle loss of control, and it can disrupt the signaling between neurons and muscles Nerve snake venom also attacks the body's adenosine triphosphate supply, a nucleotide that is important for energy transfer between cells Researchers once believed that many snake venoms contain digestive enzymes to improve the efficiency of predator-prey treatment But this is not the case Digestive enzymes in snake venom do not speed up digestion of prey This kind of snake venom is more likely to be for better phagocytosis of tissues, and the purpose is to make the prey lose the activity ability, so as to be convenient for eating Some animals are naturally immune to snake venom This immune ability can be used to deal with snake venom This technology has been used in the production of antivenom serum for the treatment of snake bites As there are more than 300 kinds of vipers in the world, many countries also have anti venom exchange programs to ensure that hospitals and treatment centers can obtain the required anti venom from other emergency institutions.
