There are three main parts of the brain;Cerebrum, Cereblum & Medula. Medulla is involved in involuntary actions such as breathing.
Because you haven't found the part of your brain that finds/makes it interesting.
The lungs, the circulatory system, and the brain :D
The heart and brain/ or lungs
The senses And the brain. The heart and lungs.
The heart and lungs work together to deliver oxygen to and remove carbon dioxide from the body's tissues. The brain uses this oxygen to function.
The emotinal brain :)
The lungs in fact do work with other organs. It works with the heart, and the brain. After the blood recieves oxygen from the lungs it will then travel to the brain and the rest of the organs.
the way that i see it is that weed goes into your lungs(if you know how to hit it).then it goes into your system(if you smoke a good amount).after that it goes into your brain and kills the bad cell and makes you relax(or if you don't blazz it makes you trip out).
The part that desires WIKIANSWERS
Your lungs are around the area of your chest.
The Brain dos all the work by telling the body to move and work
Caffeine is a stimulant, and therefore makes the processes in you brain work faster.
