All substances take up the least amount of volume in their (1.) solid phase, a little more volume in their (2.) liquid phase, and the largest amount of volume in their (3.) gas phase. The closer atoms or molecules get to one another, the less volume is occupied by the substance that they comprise.
A large, retrospective series examining human bite wounds in children found that none of the bites manifesting as abrasions became infected, while the rate of infection was much higher in bite wounds that caused punctures or lacerations.
Some of the most potent toxins active against human haemostasis are found in some Elapid venoms, while some other Elapid species cause major local tissue injury at the bite site. Conversely, there are a number of Viperid species whose principal clinical effect is neurotoxic paralysis and which produce no or minimal effect on either local tissues at the bite site or on the haemostatic system.
