Explanations learners return to.

Hyponatraemia (Hyponatremia) – classification, causes, pathophysiology, treatment
Learn about hyponatraemia, a common electrolyte imbalance characterized by low sodium levels in the blood. This video explains its classification, underlying causes, pathophysiology, and treatment strategies based on severity and symptom presentation.

Endocrinology – Renal Hormones

NSAIDs mechanism – COX, prostaglandins & pain pathway
Explore the pharmacology of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs), including their mechanisms of action, therapeutic uses, and common side effects. This video highlights how NSAIDs reduce inflammation, pain, and fever while addressing potential risks and contraindications.
Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.
See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.
“The notes I make during his videos help me retain everything better.
“The drawings are amazing and super easy to remember.
Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
Cardiac Sarcoidosis
Overview Cardiac sarcoidosis is an inflammatory heart disease caused by myocardial infiltration with non-necrotising granulomas. Inflammation may subsequently resolve, recur, or progress to permanent fibrosis. The disease is often patchy and may affect the conduction system, ventricular myocardium, papillary muscles, valves, pericardium, or coronary microcirculation. 1 Cardiac involvement may occur as part of multisystem sarcoidosis…
