The venom of a black widow spider contains neurotoxins that primarily affect the nervous system rather than directly impacting the blood. When injected, the venom can cause pain, muscle cramps, and systemic symptoms by triggering the release of neurotransmitters like acetylcholine. This can lead to increased muscle contractions and spasms, but it does not significantly alter the blood's composition or clotting properties. The effects are primarily neurological and muscular, rather than hematological.
