Overview Mitral stenosis causes an obstruction to blood flow from the left atrium to left ventricle usually as a result of rheumatic heart disease. The stenosis results in increased pressure in the left atrium, pulmonary vasculature and right side of heart. Mitral valve disease is a frequent cause of heart failure and death. Mitral valve area:…

Infective Endocarditis
Overview Infective endocarditis is a condition which occurs in the setting of bacteraemia whereby endothelial surfaces of the heart, such as valvular structures, become infected. It can present acutely or subacutely, and is often associated with fevers, new heart murmurs, constitutional symptoms and embolic phenomena. The classical organism associated is Staphylcoccus aureus, however there are…

Primary Hyperaldosteronsim (Conn Syndrome)
Overview Primary hyperaldosteronism (also known as Conn syndrome when caused by a solitary aldosterone-producing adenoma) is an endocrine disorder characterized by the autonomous, unregulated overproduction of aldosterone from the zona glomerulosa of the adrenal cortex. Under physiological conditions, aldosterone secretion is regulated by the renin-angiotensin-aldosterone system (RAAS) and serum potassium levels. In primary hyperaldosteronism, aldosterone…

Good places to begin
Explanations learners return to.

Fasted State
Learn how the body adapts during the fasted state by shifting to energy mobilization and conservation. This video explains the roles of glucagon and other hormones in promoting glycogenolysis, gluconeogenesis, and lipolysis to maintain blood glucose levels.

Mechanism of Breathing
Explore the mechanism of breathing, including how pressure changes in the thoracic cavity drive air movement during inspiration and expiration. This video explains the roles of the diaphragm, intercostal muscles, and lung compliance in ventilation.

Endocrinology – Insulin
Discover how insulin regulates blood glucose by promoting glucose uptake, glycogenesis, and lipid synthesis in this concise endocrinology overview. This educational video explains insulin's mechanisms, target tissues, and its clinical importance in diabetes and metabolic health.
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.
Carpal Tunnel Syndrome
Overview Carpal tunnel syndrome (CTS) is a compressive neuropathy of the median nerve as it passes beneath the transverse carpal ligament at the wrist. It is the most common peripheral nerve entrapment syndrome and typically causes nocturnal paraesthesia, numbness or pain involving the thumb, index finger, middle finger and radial half of the ring finger.…
