Physiology Arena

Physiology Arena is a written physiology course and a game in one app. Read the chapter, then play the system you just read.

Built for college and medical students who learn by doing rather than by re-reading a textbook.

A COMPLETE WRITTEN COURSE
Fourteen chapters, one per body system, running to roughly 69,000 words — 22 to 29 minutes of reading each. These are not flashcard summaries. Every chapter is a continuous reading page with 90 key equations, 53 worked examples carried to a real answer, and 50 clinical correlations that connect the physiology to a patient.

THE TABLES PHYSIOLOGY ACTUALLY REQUIRES
99 reference tables hold the material a course has to contain rather than gesture at: the twelve cranial nerves with function and foramen, the hormones of each axis and the cell that makes them, every nephron segment in order, the clotting cascade, the acid-base compensations. Eleven labeled anatomical plates sit beside the passages that explain them.

FOURTEEN SYSTEMS
Cells & Homeostasis · Nervous · Muscle · Cardiovascular · Respiratory · Blood & Gas Transport · Renal · Endocrine · Gastrointestinal · Fluids & Acid-Base · Reproductive · Thermoregulation · Exercise · Sensory

FIFTY-NINE LEVELS, FOUR WAYS TO PLAY
• Quiz Rush — rapid multiple choice with combos and an explanation after every answer, right or wrong
• Label Lab — tap-to-label diagrams, from feedback loops to the sarcomere
• Sim Target — tune the body to hit a goal: cardiac output, the O2-Hb curve, alveolar ventilation, GFR, acid-base balance, or fire an action potential
• Boss cases — branching clinical cases with a boss health bar: hemorrhagic shock, DKA, opioid overdose, demyelination and more

STUDY CARDS & REFERENCES
A shuffled flashcard deck drawn from every quiz question and every Learn chapter, with the answer masked until you tap, so the deck tests recall rather than recognition. References lists the physiology texts the content is written and checked against: Guyton & Hall, Boron & Boulpaep, and Costanzo.

CLIMB THE RANKS
Earn XP and rise from Pre-Med through MS-1 to MS-4, Intern, Resident, Chief, Fellow and Attending. Stars and completion are tracked for every system, and hearts regenerate over time so a bad run costs you nothing but a wait.

BUILT TO STAY OUT OF YOUR WAY
No account. No sign-in. No advertising. No analytics and no tracking of any kind. The app requests no Android permissions at all — not even internet access — so every feature works offline or in airplane mode, and your progress stays on your device.

READS WELL ON A TABLET
The chapter reader is capped and centered rather than stretching the full width of the display, so text stays at a comfortable line length on a tablet or an unfolded foldable.

SOURCES AND ATTRIBUTION
All chapter text, reference tables, worked examples and questions are original material written by BlackFox Media LLC. The anatomical plates are historical public-domain illustrations, most from Gray's Anatomy of the Human Body (1918), with kidney, digestive-tract and urinary-tract diagrams from the U.S. National Institutes of Health. Every figure carries its own credit line, and the full list is in the app under About.
