Angina Pectoris
Overview Angina Pectoris refers to the pain caused by myocardial ischaemia. Myocardial Ischaemia is usually caused by stenosis within the vessel decreasing blood flow to the muscle, but it can be caused by tachycardia, anaemia, aortic stenosis, left ventricular hypertophy and many other disease.

Glomerulonephritis
Overview Glomerulonephritis is inflammation of the glomerulus. Glomerulonephritis is classified by clinical syndrome/presentation (e.g. nephritic or nephrotic syndrome), histological appearance , or by aetiology. We will divide glomerulonephritis broadly into two broad types: Nephritic glomerulonephritis and nephrotic glormerulonephritis. Classification Two Types of Glomerular disease: Nephrotic Syndrome Nephritic Syndrome DIFFERENCE BETWEEN NEPHROTIC AND NEPHRITIS SYNDROME …

Liver Cysts
Authors Dr. Armando Faigl Areej zeeshan Ahmed Overview Liver cysts are fluid filled cavities in the liver that are asymptomatic and usually found incidentally on abdominal imaging. Larger cysts are more commonly associated with symptoms and complications.

Acute Cholecystitis
Overview Acute cholecystitis is acute inflammation of the gallbladder, usually caused by a gallstone obstructing the cystic duct. Persistent obstruction causes gallbladder distension, inflammation and possible secondary bacterial infection. Most cases are calculous, while acalculous cholecystitis occurs mainly in critically ill or severely immunocompromised patients. Cholecystectomy: surgical removal of the gallbladder. Calculous cholecystitis: gallbladder inflammation…

Explanations learners return to.
Biochemistry of Carbohydrates
Discover the biochemistry of carbohydrates, focusing on their structure, classification, and role as essential energy sources in the body. This video explains key concepts like monosaccharides, polysaccharides, and carbohydrate metabolism.
Thyroid Gland Anatomy – (embryology, blood supply, venous drainage, innervation, histology)
Explore the detailed anatomy of the thyroid gland, including its embryological development, blood supply, venous drainage, and innervation. This video also covers the gland’s histological structure and its clinical relevance in thyroid disorders and surgical procedures.
Approach to Shock – types, hypovolemic, cardiogenic, distributive, anaphylaxis, pathology, treatment
Understand the clinical approach to shock by exploring its major types—hypovolemic, cardiogenic, distributive, and anaphylactic. This video explains the underlying pathophysiology, key clinical features, and treatment strategies tailored to each form of shock.
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.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“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.
Carotid Sinus Hypersensitivity
Overview Carotid sinus hypersensitivity is an exaggerated autonomic response to stimulation of the carotid sinus. The resulting reflex may cause marked bradycardia, transient asystole, vasodilatation, hypotension, or a combination of these effects. This can reduce cerebral perfusion and produce presyncope or syncope. 1 Carotid sinus hypersensitivity is a physiological finding demonstrated during carotid sinus massage.…
