Acute Respiratory Failure
Overview Acute Respiratory Failure (ARF) is a life-threatening impairment of the respiratory system's ability to maintain adequate gas exchange. It occurs when the lungs fail to adequately oxygenate systemic arterial blood, fail to eliminate carbon dioxide produced by tissue metabolism, or both. ARF is not a disease entity in itself, but rather a sudden, critical…

Brain Herniation
Overview Brain herniation is the pathological displacement of brain tissue across rigid intracranial structures, such as the falx cerebri or tentorium cerebelli, or through an opening such as the foramen magnum. It develops when a pressure gradient forces tissue from one intracranial compartment into another. 1 Herniation may compress the brainstem, cranial nerves and cerebral…

Alcoholic Cardiomyopathy
Overview Alcoholic cardiomyopathy, increasingly termed alcohol-induced cardiomyopathy , is an acquired form of dilated cardiomyopathy caused by prolonged heavy alcohol exposure in the absence of another sufficient cause. It typically produces left ventricular dilatation and systolic dysfunction, leading to heart failure, arrhythmias, thromboembolism and sudden cardiac death. 1,2 The commonly used exposure threshold is more…

Diabetes Insipidus
56 year old lady recurrent presentations to your practice for polyuria and increased thirst. Random serum glucose and urinary glucose have returned normal. Patient has otherwise been well, complains of no dysuria, haematuria, fevers or night sweats . Overview Diabetes Insipidus (DI) is associated with inadequate arginine vasopressin (known as antidiuretic hormone) secretion or renal…

Renal Cell Carcinoma
Overview Renal cell carcinomas (originate within the renal cortex) are responsible for 85% of all primary renal neoplasms. Transitional cell carcinomas of the renal pelvis are the next most common (~8%). Renal medullary carcinoma is a rare form of RCC seen in sickle cell disease. The most common pathological type of renal cell carcinoma is clear cell…

Colorectal Cancer
Overview Colon cancer is the second most commonly diagnosed cancer. 1/12 people will develop bowel cancer before the age of 85. However, there are Survival rates are increasing. Early bowel cancer is cured by surgery alone (screening is important!!). If untreated, or diagnosed when distance metastases are present, >98% pf patients die in <5 years. Colorectal…

Atrophic Gastritis
Overview Atrophic gastritis is a chronic inflammatory disorder in which normal gastric glands are progressively lost and replaced by fibrosis or metaplastic epithelium. It is most commonly caused by chronic Helicobacter pylori infection or autoimmune destruction of oxyntic glands. The disease is often clinically silent but is important because it can cause iron and vitamin…

Good places to begin
Explanations learners return to.
Renin-Angiotensin-Aldosterone System Overview
Understand the renin-angiotensin-aldosterone system (RAAS) and how angiotensin II is formed and functions to regulate blood pressure and fluid balance. This video explains the key steps in the pathway and the organs involved, including the kidneys, liver, lungs, and adrenal glands.
Physiology of Micturition
Explore the physiology of micturition, the process of urine storage and voluntary release controlled by the nervous system and bladder muscles. This video explains the roles of the detrusor muscle, internal and external sphincters, and neural pathways involved in coordinating urination.
Bone Homeostasis (Calcium and Phosphorus) Part I
Learn how the body maintains bone health through the regulation of calcium and phosphorus balance in this educational video. Understand the key hormonal and cellular mechanisms involved in bone remodeling and mineral homeostasis—essential for physiology and clinical practice.
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.
Cervical Radiculopathy
Overview Cervical radiculopathy is dysfunction of a cervical nerve root caused by irritation or compression as it leaves the spine. It commonly produces pain radiating from the neck into one arm, sometimes with paraesthesia, numbness, weakness or altered reflexes. A disc herniation or degenerative narrowing of the neural foramen is a common cause. Diagnosis is…
