Pernicious Anaemia
Overview Pernicious Anaemia is a condition where there is lack of intrisinc factor, a glycoprotein responsible for the absorption of Vitamin B12. Vitamin B12 (Cobalamin) is an essential vitamin responsible for many physiological process in our body. Vitamin B12 deficiency causes megaloblastic anaemia and maybe accompanied by neurological abnormalities. Aetiology Pernicious Anaemia is associated with…

Anal Haemorrhoids
Overview Haemorrhoid Plexi are normal anatomical structures located within the anal canal. The term “Anal Haemorrhoids” usually refers to a pathology where the Haemorrhoidal Plexi are enlarged. They are mainly caused by chronic constipation and frequent defecation leading to dilation and engorgement of haemorrhoidal tissue. Common symptoms are bleeding, pain and itching. There are internal…

Junctional Arrythmias
Overview Junctional rhythms occur when the AV node takes over as the primary pacemaker. Junctional rhythm usually is associated with a benign course. Mechanism SA node has failed AV node just wants to be faster and takes over Enhanced automaticity in AV nodal cells AVNRT – Seperate condition where a re-entry loop stimulates the AV node…

Acute Heart Failure
Overview Acute Heart Failure (AHF) is a life-threatening medical emergency defined as the rapid onset or sudden worsening of symptoms and signs of heart failure. It results from severe cardiac dysfunction leading to inadequate systemic cardiac output, elevated intracardiac pressures, or both. AHF can present either as de novo heart failure in a patient without…

Arrythmias
Overview An arrythmia refers to any disturbance in cardiac electrical activity that is not normal sinus rhythm with normal atrioventricular conduction. This may include changes in rate, rhythm or site of origin of the electrical signal for contraction. 1 Normal conduction of the heart For the heart to pump normally 2 : SA node initiates…

Complement Deficiencies
Overview Complement deficiencies are rare primary immunodeficiencies resulting from inherited absence or dysfunction of complement proteins, regulators, or receptors. They predispose to recurrent bacterial infections, autoimmune disease (particularly systemic lupus erythematosus–like syndromes), and in some cases angioedema. Complement proteins play a central role in innate immunity by opsonisation, chemotaxis, and direct lysis of pathogens via…

Good places to begin
Explanations learners return to.
Physics Revision II – Vectors I
Master the basics of vectors in physics, including magnitude, direction, and vector representation using arrows and components. This educational video is perfect for building a strong foundation in vector analysis, essential for solving force and motion problems in exams.
Part I – Mucosal Immunity
Explore the foundations of mucosal immunity, focusing on the structural organization and key immune components of mucosal surfaces. This video introduces the roles of epithelial barriers, mucosal lymphoid tissues, and the first-line defense mechanisms against pathogens.
DiGeorge and Job syndrome – well-defined immunodeficiencies
George syndrome (22q11.2 deletion) and Job syndrome (hyper-IgE) explained with clear clinical signs and immune defects. Learn how these well-defined genetic syndromes cause recurrent infections, immune dysfunction, and characteristic physical findings. This video breaks down DiGeorge syndrome’s pharyngeal pouch failure from chromosome 22 microdeletion—remember “catch 22”—and its CATCH-22 features: cardiac defects, abnormal facies, thymic hypoplasia,…
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.

Student, Neelain University
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.
Adductor-related Groin Pain
Overview Adductor-related groin pain is a clinical entity characterised by pain localised to the hip-adductor region, with both tenderness of the adductors and recognisable pain reproduced by resisted hip adduction. It commonly affects athletes participating in sports involving kicking, sprinting, rapid acceleration, cutting or change of direction. 1 The term encompasses acute adductor injuries and…
