The document discusses how illegal drugs affect several organs in the human body. It explains that drugs enter the bloodstream and are quickly transported to the brain, where they interfere with neurotransmitters and disrupt the limbic system. It also notes that drugs can directly weaken the heart's ability to pump blood normally, increasing risks of heart attack. The lungs can absorb large amounts of drugs instantly, potentially leading to overdose by clogging the bronchi. Repeated drug use may also cause liver disease or infection and impair its ability to break down chemicals.

1. How Drugs Affect The Human
Body!
Luis Jurado
Anatomy & Physiology

2. Introduction
In this power point I will be discussing the
consequences your body takes from taking
drugs that are illegal. Including The brain, the
heart, the liver, the lungs, and pregnancy.

3. The Brain
Any time you take drugs for what ever your reason, the faster it
reaches your brain, the more the drug will take affect. Drugs that are
injected by needles into your veins is the most dangerous way for
drugs to affect the brain.
Once a drug reaches your brain some thing called
neurotransmitter takes place. Neurotransmitters are just
chemicals formed by a drug. A better definition is it controls
the flow of information within the brain between neurons or
brain cells that form a synapse(Gap).
The human body needs to send cells so that the brain may receive
what ever information it needs to have. Illegal drugs affect the
brain by preventing the brain to have to much of
neurotransmitters . Most importantly it is bad for the brains
circuit (limbic system).

4. The Heart
Once a person takes a drug, it enters your bloodstream and from there the heart pumps blood
containing the drug to the brain as it will affect how people feel. Drugs can also have affect on
the heart directly exacerbate heart disease. This weakens the hearts ability to pump blood
normally. Drugs that take affect to the heart will more likely to be at risk of a heat attack ,
especially for people that already have heart problems.
Dugs make your heart pump to much blood. That being said your body is not use to handling
the changes so when the drug is done taking its affect on the heart you heart is exhausted and
pumps a low amount blood which then would end up affecting the brain .

5. The Lungs
Once a dug is taken the liver breaks down the chemical structure of the drug. Since its
some thing the liver dose not recognize it sits there . Because the lungs provide us to
breath oxygen in and breath out if you were to inhale anything it enters your body blood
an ultimately affects the heart and brain.
The lungs ability to absorb large amounts of these drugs in a short space of time, about 8
seconds which means that the drugs can be almost instant and very powerful. Another
way drugs an hurt you lungs is insufflation. It is mostly used for people who have asthma,
but because you took a drug it attacks the lung cells bronchi's , or even suffocation or
overdosing , due to the drug clogging the bronchi's

6. The Liver
The liver is one of the most important organs in the human body. By taking drugs over and over
again you can develop a liver disease.
You need your liver to stay healthy. Illegal dugs may cause infection to the liver
which would cause failure to your body an it builds on from their. The most
common way to hurt your lungs is smoking marijuana , crack ,heroin etc..
Drugs that are inhaled are solvent poppers and nitrous oxide
