Diabetes Mellitus type I
Overview Type 1 Diabetes Mellitus (T1DM) is a chronic, autoimmune metabolic disorder characterized by the progressive, T-cell-mediated destruction of insulin-producing pancreatic beta-cells within the Islets of Langerhans. This severe loss of functional beta-cell mass results in absolute insulin deficiency, leaving affected individuals entirely dependent on exogenous insulin for survival. Without sufficient insulin, tissues cannot take…

Cervical Cancer
Overview Cervical cancer is an HPV-related malignancy of the uterine cervical mucosa. Most cervical tumours contain HPV DNA (99.7%) . There are many variants of HPV, HPV-16 and 18 are the 2 most common high-risk types. Cervical cancer is proceeded by an idenifiable precursor lesion (cervical intraepithelial neoplasia (CIN1)) that may progress to invasive cancer. CIN can…

Cardiac Amyloidosis
Overview Cardiac amyloidosis is an infiltrative cardiomyopathy caused by extracellular deposition of misfolded protein fibrils within the myocardium, conduction system, valves and intramyocardial vessels. Progressive amyloid accumulation increases ventricular wall thickness and stiffness, producing restrictive physiology, heart failure, arrhythmias and conduction disease. 1,2 More than 98% of clinically recognised cardiac amyloidosis is caused by either:…

Plantar Fasciitis
Overview Plantar fasciitis is a common cause of plantar heel pain associated with repetitive loading of the plantar fascia, the fibrous band that supports the longitudinal arch of the foot. The term plantar fasciopathy is often used because chronic cases show degenerative change rather than prominent inflammation. It typically causes pain beneath the medial heel…

Psoriasis
Overview Psoriasis is a chronic, immune-mediated, inflammatory skin disease with systemic associations, characterized by sharply demarcated erythematous plaques with overlying scale, most commonly plaque psoriasis. [1-4] It affects about 1% to 3% of the global population, although prevalence varies by geography and ethnicity, and plaque psoriasis accounts for about 80% to 90% of cases. 1,2…

Iron Deficiency Anaemia
Overview In the clinical setting, iron deficiency is the most common cause of anaemia. Iron Deficiency is lack of iron in the body resulting from inadequate iron intake, increased iron loss and increased iron demand which can lead to anaemia. Iron is an integral part of haemoglobin the oxygen carrying protein. Without iron, oxygen is unable to…

Osteomalacia / Rickets
Overview Osteomalacia (adults) and rickets (children) are disorders of impaired bone mineralisation leading to soft, poorly mineralised bone. It arises when there is insufficient calcium–phosphate supply to the mineralising matrix due to vitamin D deficiency, calcium deficiency, phosphate deficiency (often FGF23-mediated). Nutritional rickets still occurs worldwide, while hypophosphataemic forms (e.g., XLH, tumour-induced osteomalacia) are rarer…

Videos
Hand-drawn explanations that build the big picture as the concept unfolds.
Notes
Clear written explanations for review, reference and filling in the details.
Diagrams
Visual snapshots that help you easily review topics.
Questions
Test whether the explanation stayed with you—not just whether it looked familiar.
Good places to begin
Explanations learners return to.
Homeostasis – negative and positive feedback (thermoregulation and lactation)
Explore the concept of homeostasis and how the body maintains internal balance through negative and positive feedback mechanisms. This video illustrates key examples like thermoregulation and lactation to explain how these feedback loops function in real physiological processes.
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.
Bilirubin Metabolism
Understand bilirubin metabolism, from the breakdown of hemoglobin to its processing in the liver and excretion in bile. This video explains the steps involved, including conjugation, transport, and the clinical relevance of elevated bilirubin levels.
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…
