Cardiac Arrest (including post-arrest care)
Overview Cardiac arrest is a state of circulatory failure due to a loss of cardiac systolic function. It is the result of 4 specific cardiac rhythm disturbances: Ventricular fibrillation Pulseless ventricular tachycardia Pulseless Electrical activity Asystole Epidemiology Survival is estimated at <20% for patients presenting out-of-hospital with VF, and <10% overall for patients presenting with…

Developmental Hip Dysplasia
Overview Developmental Dyplasia of the hip (DDH) is previously known as congenital dislocation of the hip (however name changed as some of the hip problems develop after birth). Spectrum of condition related to development of the hip in infants and young children. Includes abnormal development of the acetabulum and proximal femur + mechanical instability of the hip joint. Usually involves…

Coeliac Disease
Overview Coeliac disease is a systemic autoimmune disease triggered (T-lymphocytes) by dietary gluten peptides found in wheat, rye, barley, and related grains. Immune activation in the small intestine leads to villous atrophy, hypertrophy of the intestinal crypts, and increased numbers of lymphocytes in the epithelium and lamina propria. Locally these changes lead to gastrointestinal symptoms and malabsorption.…

Myelofibrosis
Overview Myelofibrosis is a type of myeloproliferative diseasecharacterized by clonal myeloid expansion, followed by progressive fibrous connective tissue deposition in the bone marrow, resulting in bone marrow failure. Clonal evolution can also occur, with an increased risk of transformation to acute myeloid leukemia. In addition, disabling constitutional symptoms secondary to the high circulating levels of…

Spermatocele
Overview A spermatocele, or spermatic cyst, is a benign fluid-filled cyst arising from the epididymis, usually near the upper pole of the testis. It commonly contains clear or milky fluid with spermatozoa. Most spermatoceles are painless, discovered incidentally and do not require treatment. Epididymis: coiled structure behind the testis that stores and transports sperm. Spermatocele:…

Bowel Obstruction
Overview Bowel obstruction is a blockage of intestinal contents, either mechanical (e.g., adhesions, hernias, malignancy) or functional (e.g., ileus), leading to impaired transit, proximal dilation, and downstream complications including ischaemia and perforation if untreated. Key features of bowel obstruction include colicky abdominal pain, distension, nausea with bilious or faeculent vomiting, obstipation, initially high-pitched then absent…

Long-Term Complications of Diabetes (Overview)
Overview Long-term complications of diabetes are chronic injuries affecting blood vessels, nerves and organs in both type 1 and type 2 diabetes. The principal groups are microvascular disease (retinopathy, kidney disease and neuropathy) and macrovascular disease (coronary, cerebrovascular and peripheral arterial disease). They may develop silently before causing visual loss, kidney failure, pain, disability or…

Malaria Pathophysiology
Discover the pathophysiology of malaria, from Plasmodium infection to red blood cell destruction and systemic complications. This video explains the disease mechanisms behind fever cycles, anemia, and organ involvement in a clear, exam-focused format.
Renin-Angiotensin System (Renin,Prorenin)
Learn when, where, and how renin is secreted, and understand the activation of prorenin into renin in the Renin-Angiotensin System. This educational video explains key regulatory steps essential for blood pressure control and clinical insight into hypertension and renal physiology.

Discover how microscopes reveal the hidden microbial world—light, fluorescent, and electron microscopy explained with practical applications and diagnostic value. In this clear, engaging video you'll learn how magnification and resolution work, why staining and contrast techniques make bacteria visible, and which microscopy methods suit specific tasks: bright-field for basic morphology and gram stains; dark-field for…
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.
Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…
