What type of toxins are represented by spider bites?

Spider bites introduce toxins into the body through the skin. This method of delivery characterizes them as injected toxins. When a spider bites, it uses its fangs to puncture the skin, allowing the venom to enter the bloodstream or surrounding tissues directly. This contrasts with absorbed toxins, which enter the body through the skin or membranes; inhaled toxins, which enter through the respiratory system; and ingested toxins, which are consumed and enter through the digestive system. The direct delivery of venom into the tissues makes injected toxins the correct classification for the toxins associated with spider bites.
