For a minute while you read:
1) Your eyes will transform the image into electrical signals (nerve impulses) that will channel the information into your brain for processing.
2) In addition to receiving and processing information, such as visual input, your brain will produce output to the muscles to maintain posture, and move your eyes while reading. Intermediary chemical substances shall carry signals between nerves and your muscles to generate appropriate muscle contraction.
3) Your heart will beat 70 times, pumping 5 liters of blood to the lungs and 5 liters of others to other parts of the body.
4) You will attract and exhale about 12 times, 6 liters of air exchange between the atmosphere and your lungs.
5) Your cells will consume 250 ml 200 ml of oxygen and produces carbon dioxide.
6) More than 1 liter of blood will flow through both of your kidneys, kidney where it will process the blood to hold the substances are "necessary" and dispose of substances that are "not needed" into the urine. Your kidneys will produce 1 ml of urine in 1 minute.
7) Your digestive system will process your last meal to be transferred into the bloodstream and subsequently distributed to different cells.
8) You will use about 2 calories of energy from food to support "living expenses" your body plus your muscles to contract would lead to burning extra calories.
