Alejandro has started to use herion. How will this most likely affect her body system?
It will fill the lungs with toxic material
It will release serotonin and dopamine to the brain
It will block the transmission of pain signals to her brain
It will slow down the central nervous system
It will slow down the central nervous system
All of the given options can occur when an individual uses heroin.
- Heroin can fill the lungs with toxic material when it is smoked or injected, leading to respiratory problems and potentially lung damage.
- Heroin use can also release serotonin and dopamine in the brain, which are neurotransmitters responsible for pleasure and reward. This can produce an intense feeling of euphoria.
- Another effect of heroin is its ability to block the transmission of pain signals to the brain, resulting in pain relief.
- Additionally, heroin can slow down the central nervous system, leading to decreased heart rate, breathing rate, and overall decreased body function.
It is important to note that heroin use can have severe and potentially life-threatening consequences on various body systems, including the respiratory and central nervous systems.
Out of the given options, the correct answer is: It will slow down the central nervous system.
Heroin is an opioid drug that affects the body's central nervous system (CNS). When Alejandro uses heroin, it binds to opioid receptors in the brain, spinal cord, and other organs, leading to a slowing down of the CNS. This can result in a number of physiological effects, including:
1. Depressed respiration: Heroin can suppress the activity of the respiratory system, causing breathing to become slower and shallower. This may lead to decreased oxygen supply to the body's organs, including the lungs.
2. Decreased heart rate: Heroin use can lower heart rate and blood pressure, which can have negative consequences on cardiovascular health.
3. Constipation: Heroin can affect the digestive system, causing a reduction in gastrointestinal activity and resulting in constipation.
4. Suppressed immune system: Chronic heroin use can weaken the immune system, making individuals more susceptible to infections and diseases.
5. Constricted pupils: One recognizable sign of heroin use is pinpoint pupils, as the drug affects the muscles that control the size of the pupils.
Although all the options you provided have some connection to heroin use, it is the slowdown of the central nervous system that is the most prominent and significant effect of heroin on the body.
