Pathophysiology
Welcome to Bullo Academy’s Pathophysiology video-learning library. This page is designed to help nursing students connect clinical signs and symptoms with the underlying disease mechanisms through clear, concise video segments and focused review resources.
Use this page as a companion to your lectures, lab experiences, and required readings. Work through the topics in order or jump directly to the system you are reviewing before class, simulation, or exams.
Course Overview
This Pathophysiology page organizes key concepts into system-based topic sections. Within each topic, you will find a brief orientation to what you should focus on, along with clearly labeled video placeholders where instructional videos will be added.
As you study, use each section to:
- Preview core mechanisms before class to build a foundation for new content.
- Revisit complex pathways, compensatory responses, and clinical correlations after lectures or simulations.
- Pause and take notes on definitions, key steps, and nursing implications once videos are added.
- Connect changes at the cellular and system level with common signs, symptoms, and lab findings.
The Study Resources section at the bottom of this page will provide quick links to practice tools, reference summaries, and additional study aids that align with these topics.
Foundations of Pathophysiology
This section introduces core concepts such as homeostasis, disease processes, risk factors, and how normal physiology changes as illness develops. Use these foundations to frame every other topic on this page.
Video placeholder — Foundations of Pathophysiology (video to be added)
This container will hold an introductory video explaining core terms, health and disease continuums, and how to approach pathophysiologic thinking as a nursing student.
Cellular Injury and Adaptation
Explore how cells respond to stress, injury, and aging through reversible adaptations, irreversible damage, and cell death. Understanding these processes helps you interpret early changes that may lead to disease.
Video placeholder — Cellular Injury and Adaptation (video to be added)
This area will contain a video overview of types of cellular injury, adaptive responses (such as hypertrophy and atrophy), and examples relevant to common nursing conditions.
Inflammation and Healing
This topic reviews acute and chronic inflammation, the cardinal signs, mediators involved, and the stages of tissue healing. Link these mechanisms to clinical assessment findings and nursing care.
Video placeholder — Inflammation and Healing (video to be added)
This container will hold a video walking through the inflammatory response, normal versus impaired healing, and clinical examples (such as surgical wounds and infections).
Fluid, Electrolyte, and Acid–Base Balance
Here you will connect body fluid distribution, electrolyte regulation, and acid–base balance with common imbalances seen in clinical practice. Focus on causes, compensations, and priority assessments.
Video placeholder — Fluid and Electrolyte Balance (video to be added)
This placeholder will contain a video on fluid compartments, movement, and common volume imbalances.
Video placeholder — Acid–Base Balance (video to be added)
This placeholder will hold a video reviewing buffer systems, respiratory and metabolic components, and interpreting basic arterial blood gas patterns.
Immunity and Infection
This section links innate and adaptive immune responses with infection risk, hypersensitivity reactions, and immune deficiencies. Apply these concepts to common infectious and autoimmune disorders.
Video placeholder — Immunity and Infection (video to be added)
This container will hold a video explaining immune system organization, typical infection patterns, and links to nursing assessment and isolation precautions.
Cardiovascular Disorders
Review how changes in cardiac output, vascular resistance, and blood flow lead to common cardiovascular disorders. Emphasize links between underlying mechanisms, clinical manifestations, and priority nursing actions.
Video placeholder — Cardiovascular Disorders Overview (video to be added)
This placeholder will hold a video summarizing major cardiovascular pathophysiology, such as hypertension, heart failure, and ischemic heart disease.
Respiratory Disorders
This topic focuses on ventilation, diffusion, and perfusion, and how disruptions in these processes lead to respiratory disorders. Connect gas exchange problems with typical assessment findings and priority interventions.
Video placeholder — Respiratory Mechanics and Gas Exchange (video to be added)
This placeholder will hold a video describing basic respiratory physiology and how it changes in disorders such as asthma, COPD, and pneumonia.
Neurological Disorders
Connect the structure and function of the nervous system with common neurologic disorders. Emphasize perfusion, intracranial pressure, and neuronal communication as you link mechanisms to assessment and safety priorities.
Video placeholder — Neurological Disorders Overview (video to be added)
This container will hold a video summarizing key neurologic conditions and how pathophysiology informs focused neuro assessments.
Endocrine and Metabolic Disorders
This topic covers how hormonal regulation and metabolic pathways become disrupted, leading to disorders such as diabetes, thyroid disease, and adrenal dysfunction. Focus on feedback loops, compensations, and clinical patterns.
Video placeholder — Endocrine and Metabolic Disorders (video to be added)
This placeholder will hold a video explaining major endocrine pathways, common imbalances, and how to connect lab findings with patient presentation.
Renal and Urinary Disorders
Explore how the kidneys and urinary system regulate fluid, electrolytes, and waste removal, and how dysfunction leads to acute and chronic renal conditions. Connect these mechanisms to labs, urine characteristics, and clinical monitoring.
Video placeholder — Renal and Urinary Disorders (video to be added)
This container will hold a video reviewing key renal functions, stages of kidney injury, and how these changes appear in patient data and assessment findings.
