Answer 1

The most likely effect of heroin on Alejandra's body systems is that "It will slow down the central nervous system."

Heroin is an opioid, and its primary action is to depress the central nervous system. This can lead to a range of effects, including pain relief, sedation, decreased respiratory rate, and potentially life-threatening respiratory depression. While heroin does affect pain signals and can impact neurotransmitters like serotonin and dopamine, its most prominent and immediate impact is on slowing down central nervous system functions.
