    13) + 14) Caffeine passes through the body membranes from the first sip, entering your blood stream through the lining of your mouth, throat, and stomach. It only takes 45 minutes for 99% of the caffeine to be absorbed through these membranes. As soon as the caffeine enters the body it is already being metabolized by the liver and broken down into theophylline, theobromine and paraxanthine. From there these chemicals travel throughout the body where they affect various body functions. The most studied of these is the way caffeine is similar to the molecule adenosine in the brain. The caffeine molecules bind to the adenosine receptors in brain cells and block adenosine from binding. This causes elevated levels of adenosine in the blood which is believed to cause feelings of alertness and energy. The compounds also interact with the dopamine system in the brain which influences mood and prevents dopamine’s calming effect. Theophylline relaxes smooth muscles, which has been beneficial to those with asthma and is the reason why after drinking caffeine a person often feels the need to use the bathroom as it is affecting the smooth muscle of the colon. Theobromine increases the amount of oxygen and nutrients that can be used by the brain and muscles. The caffeine metabolites are then filtered by the kidneys and they exit the body with the urine. Caffeine has been shown to have a diuretic effect on the body, which basically causes the body to release more water in the urine. However, new research suggests that this is only in people who have not built up tolerance to the caffeine molecule.…

    According to National Geographic's January edition, less than 200 years ago, people figured out that the buzz they got from coffee and tea was the same chemical. In 1820, after coffee shops had spread across Western Europe, the German chemist Friedlieb Ferdinand Runge first isolated the drug in a coffee bean. The newly discovered drug was dubbed "caffeine" meaning something found in coffee. Scientists then began to find caffeine in many of its natural forms. In more than 60 plants, scientists found caffeine in kola leaves, cacao pods, and tea leaves just to name a few. Caffeine motivated the industrial revolution in Western Europe. Boiling water to make coffee or tea helped decrease the spread of disease between workers. Also, the caffeine in their systems kept them from falling asleep while working the machines. In a sense, caffeine is the drug that makes the modern world possible. Without that useful jolt of coffee or diet coke or Red Bull to get us out of the bed and back to work, the 24-hour society of the developed world couldn't exist.…

    II. Caffeine is believed to work by blocking adenosine receptors in the brain and other organs. This reduces the ability of adenosine to bind to the receptors, which would slow down cellular activity. The stimulated nerve cells release the hormone epinephrine (adrenaline), which increases heart rate, blood pressure, and blood flow to muscles, decreases blood flow to the skin and organs, and causes the liver to release glucose. Caffeine also increases levels of the neurotransmitter dopamine.…
