Digestion & Liver
The path food takes and what the liver does with what is absorbed: peristalsis, stomach acid, pancreatic enzymes and bile-acid fat digestion, then the gut barrier and its microbiome. The liver side covers detoxification, glucose release, bilirubin handling, and how alcohol and swallowed drugs are metabolised on first pass.
Every page here is a hands-on animated diagram, not a video — press play, slow it down, break the mechanism on purpose, and read the live values in real clinical units. They explain how a process works; they are not medical advice, and the evidence for any treatment lives on the topic pages each animation links into.

The Animations (13)
How a Pill Travels Through You: ADME
Swallow a pill and follow it through absorption, the liver’s first-pass cut, distribution, CYP450 metabolism and kidney excretion — then block an enzyme with grapefruit and watch the levels climb.
Launch animation →What Alcohol Does Inside Your Liver
Ethanol becomes acetaldehyde becomes acetate — and the NADH that piles up shuts down fat burning, stalls your blood sugar and drives up uric acid. Nothing speeds it up. Nothing.
Launch animation →Digestion
Send a meal down the tract and watch enzymes and acid break carbs, protein and fat into absorbable units — with a pH meter that shifts from stomach to intestine.
Launch animation →How the Liver Keeps Your Blood Sugar Steady
Watch the liver bank glucose as glycogen after a meal and release it between meals to hold your blood sugar steady — then fast long enough to make new glucose from scratch, or watch diabetes over-pour it overnight.
Launch animation →The Gut Barrier & Microbiome
Ferment fibre into butyrate and watch it tighten the gut wall — then starve the microbes of fibre and see them start eating your mucus layer instead.
Launch animation →Peristalsis: How Food Actually Moves Through You
Push a bolus down the gut with a contract-behind, relax-ahead muscle wave run by the gut’s own 500-million-neuron brain — then switch to mixing, the housekeeper wave, or a stalled diabetic stomach.
Launch animation →How the Liver Detoxifies
Watch Phase I make a toxin more reactive and Phase II neutralise it — and see exactly why a juice cleanse changes nothing at all.
Launch animation →Bilirubin, Jaundice & Why Skin Turns Yellow
Follow a worn-out red cell’s pigment to the liver to be conjugated and sent out in bile — then block a step and watch bilirubin climb until the skin turns yellow, the way it does in newborns and gallstones.
Launch animation →How Cavities Form
Feed the plaque bacteria sugar and watch the acid they make dissolve enamel from below the surface — then brush with fluoride and watch the tooth re-harden before a cavity breaks through.
Launch animation →Bile Acids: How You Digest Fat
Eat a fatty meal and watch bile squirt from the gallbladder to emulsify the fat into droplets lipase can attack — then block the bile and watch the fat, and the vitamins A, D, E and K, go straight through.
Launch animation →Nausea & Vomiting: The Body’s Eject Button
Watch four alarm lines — the gut, a blood-sampling brain zone, the inner ear and the mind — converge on the vomiting centre and fire the eject reflex, then calm each with its matching anti-sickness drug.
Launch animation →The Pancreas: Your Digestive Enzyme Factory
Pour amylase, lipase and protease plus bicarbonate into the gut to digest a meal — then block the duct with a gallstone and watch the enzymes switch on inside and digest the pancreas itself.
Launch animation →Stomach Acid, pH & the PPI Trade-off
Run the proton pump that drives your stomach to pH 2, activate pepsin and free your B12 and iron — then take a PPI and watch the pH climb while the nutrients stop being released.
