What Just Physiology does

Just Physiology (JustPhysiology, LLC) is an online educational software company that provides interactive physiology simulations for undergraduate students in biomedical engineering, biology, nursing, physical therapy, and physiology programs. The platform is powered by HumMod, a proprietary mathematical model of integrative human physiology that simulates cardiovascular, renal, respiratory, endocrine, and metabolic systems in faster-than-real time. Students access a library of case study modules covering scenarios such as Exercise, Heart Failure, Hemorrhage, High Altitude Physiology, Fight or Flight, Carbon Monoxide Poisoning, and Pneumothorax, and can use an integrative graphing system to explore variable interdependencies.

The company monetizes through two channels: individual self-serve subscriptions priced at $40 for six months of access, processed via PayPal, and classroom/institutional licenses priced per student at $30 (graduate/medical), $20 (4-year college), or $10 (2-year college), with instructor access provided free. JustPhysiology, LLC operates as a subsidiary of HC Simulation, LLC, headquartered at 1577 Barnes Road in Canton, Mississippi, with 1–10 employees. The product is restricted to US residents under its EULA and is currently distributed through direct website sales and instructor outreach.

Development has been supported by National Science Foundation grants (IUSE 1504792 and EPS 0903787), a National Heart, Lung, and Blood Institute award (PO1 HL51971), and a $441,000 SBIR grant in September 2018. The product was co-founded by Robert L. Hester, Ph.D. (University of Mississippi Medical Center) and David Julian, Ph.D. (University of Florida). No venture capital funding rounds, enterprise customers, or geographic expansions beyond the US are recorded in the available data.

Core offering

Just Physiology provides an online, web-based human physiology simulation software powered by the HumMod mathematical model. The platform enables students to explore how the body responds to normal and pathological conditions through interactive case studies and customizable simulations covering cardiovascular, renal, respiratory, endocrine, and metabolic systems. The product is sold via individual subscriptions and classroom/institutional licenses to undergraduate and graduate students in biomedical, biology, nursing, physical therapy, and physiology programs.

Product overview

JustPhysiology is a single unified online simulation platform for physiology education, powered by the HumMod mathematical model. The core product is the JustPhysiology Simulation Software, which provides access to an expanding library of case study modules including Exercise, Heart Failure, Hemorrhage, High Altitude Physiology, Fight or Flight, Syndrome of Inappropriate ADH, A-V Fistula, Baroreceptor Reflex, Carbon Monoxide Poisoning, and Pneumothorax. Students can also use an Integrative Graphing Feature and Basic Responses Module to explore and visualize physiological variables. The platform is designed for undergraduate students in biomedical engineering, biology, nursing, and physiology programs.

Broad incumbents

• Pearson PhysioEx: PhysioEx is a widely adopted physiology lab simulation included in Pearson's higher education portfolio. Comparable to Just Physiology as it targets the same A&P and physiology course market with computer-based simulations, though it is bundled into a much broader publisher ecosystem.
• A.D.A.M. Interactive Anatomy: A.D.A.M. Interactive Anatomy is an established digital anatomy and physiology learning product used widely in undergraduate health sciences. Comparable as a packaged EdTech simulation tool for healthcare education, though focused more on anatomy than integrative physiology.
• Osmosis (Elsevier): Osmosis, now part of Elsevier, delivers video-based medical and physiology education to students and institutions globally. Comparable as a subscription EdTech platform serving nursing, medical, and allied health curricula.
• Laerdal SimMan: Laerdal provides manikin-based patient simulators widely used in nursing and medical simulation centers. Comparable as a healthcare simulation provider but operates in physical high-fidelity simulation rather than pure software.

Direct peers

• Visible Body: Visible Body provides interactive 3D anatomy and physiology learning tools used by nursing, PT, and biology students. Directly comparable as a subscription-based physiology/anatomy educational software platform serving the same student segments.
• Complete Anatomy (3D4Medical / Elsevier): Complete Anatomy is a 3D anatomy/physiology platform for medical and allied health students. Comparable as a subscription simulation tool targeting overlapping student cohorts in medicine, nursing, and PT.
• BioDigital Human: BioDigital Human provides an interactive 3D virtual body for medical education and patient communication. Comparable as a digital human-physiology platform used in health sciences curricula and professional training.
• i-Human Patients (Kaplan): i-Human Patients is a cloud-based patient simulation platform for nursing and medical education. Comparable as a clinical/physiology simulation tool used in health professional training programs.

Emerging players

• Body Interact: Body Interact offers virtual patient simulators for nursing and medical schools. Comparable as a scenario-based clinical simulation aimed at the same health sciences education buyer.

Regional players

• HeartWorks: HeartWorks delivers echocardiography and cardiac anatomy simulation for clinical education. Comparable as a physiology-focused simulation product but narrower in scope, focused on cardiac imaging training.
