I’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Organs Zone. It has scientists studying health and disease in various parts of our bodies. Who gets the prize? YOU decide!
Hi Katnissmar and 123becca
This is a very interesting question and one which we haven’t really studied in enough detail.
Caffeine is a stimulant which means it acts to increase heart rate, blood flow, levels of sugar in your blood. It is also a diuretic which means it makes you go to the toilet more often and reduces the amount of water which is reabsorbed.
This means that caffeine acts on your large intestine to prevent water being reabsorbed. It also helps speed up the digestive process (increasing absorption which increases blood sugar levels) – which is why most people feel their guts become ‘active’ and need to go to the toilet!
Because of caffeine’s stimulant effects, it should only be consumed in moderation!!
