Anaphylaxis
Overview Anaphylaxis is a severe, systemic hypersensitivity reaction that is rapid in onset and potentially fatal, most often triggered by foods, medications, or venom; global incidence is ~50–112 per 100,000 person-years with rising emergency presentations in many regions, including Australia [1,2,4] . Mortality is low but non-trivial and is driven by airway obstruction, severe bronchospasm,…

Birth Defects
Overview Birth defects are the leading cause of perinatal and post- neonatal deaths, and result in substantial morbidity and disability in developed countries. There is a wide variety of mechanisms including genetic, environmental and multifactorial. Major birth defects affect 2–3% of live-borns, and minor birth defects affect 15%. Preventative strategies remain limited, but include maternal folic acid supplementation,…

Aortic Aneurysm
Overview An aortic aneurysm is a pathological dilatation of the aorta caused by weakening of the arterial wall. It may involve the aortic root, ascending aorta, arch, descending thoracic aorta, thoracoabdominal aorta or abdominal aorta. Most aortic aneurysms are asymptomatic and are discovered incidentally or through screening. Progressive enlargement increases the risk of rupture, dissection,…

Leukaemia
Overview Leukemia is a common malignancy in children and adults that occurs when alterations in normal cell regulatory processes cause uncontrolled proliferation of hematopoietic stem cells in the bone marrow. Leukaemia: Clonal proliferation of hematopoietic stem cells in the bone marrow Acute Leukaemia: Clonal proliferation of hematopoietic stem cells in the bone marrow that develops…

Pulmonary Embolism
Overview Pulmonary embolism occurs most often from a dislodged thrombus from the lower limb (DVT). The embolus travels towards the lung and becomes lodged in the pulmonary artery resulting in infarction of the lung tissue. Pulmonary Embolism: Deep Vein Thrombosis (DVT): Blood clot in the deep venous system that usually affects the lower extremities or…

Eosinophilic Granulomatosis with Polyangiitis
Overview EGPA (formerly Churg-Strauss syndrome) is a rare, small-to-medium vessel necrotizing vasculitis characterized by asthma, eosinophilia, and extravascular granulomas. It commonly affects the lungs, skin, peripheral nerves, and heart. Annual incidence: ~1–3 per million; peak onset in 40s–60s; no significant gender bias. Strongly associated with MPO-ANCA positivity in ~40–60% of patients; others are ANCA-negative. Eosinophilia…

Rhesus Hemolytic Disease
Rhesus haemolytic disease Overview Rhesus haemolytic disease, more accurately called RhD haemolytic disease of the fetus and newborn (HDFN), occurs when maternal IgG antibodies against the RhD antigen cross the placenta and destroy RhD-positive fetal red blood cells. It usually develops after an RhD-negative mother has previously been sensitised by pregnancy, fetomaternal haemorrhage or transfusion.…

Good places to begin
Explanations learners return to.
Clinical Anatomy – Cardiac Coronary Vessels (left and right coronary artery, venous sinus)
Explore the clinical anatomy of the heart's coronary vessels, including the left and right coronary arteries and the coronary sinus. This video breaks down their structure, function, and relevance in cardiac circulation and disease.
Immunology Map IV – Innate Immune response II
Delve deeper into the innate immune response by examining the roles of inflammatory mediators, the complement system, and natural killer (NK) cells. This video highlights how these components work together to recognize and eliminate pathogens quickly and effectively.
Pharmacology – Antiepileptics
Explore the mechanisms of action, indications, and side effects of common antiepileptic drugs used in seizure management. This video simplifies key pharmacological concepts behind medications like phenytoin, valproate, carbamazepine, and newer agents.
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.
Chronic inflammatory demyelinating polyneuropathy (CIDP)
Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
