Read the passage given below and answer the following questions.
All snakes are hunters and predators, feeding on the animals and sometimes their eggs. Having no limbs, snakes cannot hold their preys down to bite; hence, they usually swallow them whole. Poisonous snakes sometimes do immobilise their preys with their venom to make consumption easier. It is truly a myth that poisonous snakes attack humans for food. Humans are too large for snakes to gulp down and that is why they can never make humans their prey to satiate their hunger. In cases where snakes do bite, these attacks are usually defensive ones and the venom injected is normally little or sometimes even none. The full fatal dose of the venom is only released on smaller animals which the snakes can swallow easily. Besides helping in the killing and immobilising of their prey, the poison also acts as a digestive agent for snake. Why then is the venom so deadly? In general, there are three kinds of poison in the venom, though in varying amounts, depending on the type of snake in question. Venoms usually contain substances that weaken the blood corpuscles and the lining of the blood vessels. Profuse bleeding, often a common result of snake -bites, is caused by the anticoagulants present in the poison which prevents blood clotting. The paralysis of the heart and respiratory muscles is performed by the nervous system attacking toxins.
Though these bites are deadly, certain actions can be taken to slow down the spread of the venom; hence, saving the victim’s life. Attempting to incise and suck at the spot of the bite is more likely to be harmful than a cure. The poisonous venom usually travels fast into the body upon being released; hence, sucking at the mouth of the wound will not help remove the poison, rather, incising the bite may lead the victim to great pain and further profuse bleeding. Instead, a broad, firm crepe bandage should be applied over the wound and up the full limb to compress the tissues and prevent the spread of the venom. After which, the victim must be duly sent to the hospital for professional treatment.
Accurate statistics of the incidence of snakebite and its morbidity and mortality throughout the world do not exist; however, it is certainly higher than what is reported. This is because even today most of the victims initially approach traditional healers for treatment and many are not even registered in the hospital.
