Study Notes

Exam 3 Review Topics

Pathophysiology Exam 3: Covers chapters 9, 19, 7, 18, and 20 of the Applied Pathophysiology textbook.

Chapter 9: Altered Acid-Base Balance

Physiological pH: Understanding acidosis and alkalosis through serum (blood) pH levels.
Importance of pH: Maintaining physiologic pH is crucial for cell and tissue function.
Buffer Systems: The body uses three buffer systems to regulate pH. Details on how they work are needed.
Acidosis and Alkalosis: Identify the implications of deviations from the normal pH range on cells and tissues.

Chapter 19: Degenerative Changes in Aging

Aging vs. Pathophysiology: Differentiate between expected changes in aging and pathological changes.
Manifestations of Aging: Understand the various categories of aging manifestations, using figure 19.2 in the textbook as a guide.
Specific Models: Models of osteoporosis and Alzheimer's disease.

Chapter 7: Altered Cellular Proliferation and Differentiation

Proliferation vs. Differentiation: Key differences between these two processes (refer to chapter 2 for review).
Cancer Definition: Defining cancer and neoplastic cells; describing characteristics of cancer cells.
Carcinogenesis: Understand how cancer develops (include genetic mutations and how the body tries to fix them).
Cancerogenic Environments: Factors that contribute to the development of cancer (e.g., polymorphisms, epigenetic changes).
Cancer Formation and Carcinogens: Learn about carcinogens, how they work, and why they contribute to cancer development.

Chapter 18: Altered Elimination

Urine Production and Removal: Explain the function of the nephron and glomerulus, how the kidneys reabsorb and excrete substances.
Urine pathway: Describe the journey of urine from the kidneys to outside of the body

Chapter 20: Integrated Pathophysiologic Concepts (Glucose Regulation and Diabetes)

Glucose Regulation: Details of how glucose is processed in the body, including the role of insulin and the pancreas.
Understanding Diabetes: Understand type 1, type 2, and gestational diabetes, including causes, symptoms, diagnoses, and treatments for each.
Specific Complication of Diabetes: Understand complications like microvascular and macrovascular problems, hypoglycemia- issues surrounding DKA and HHNK, Somogyi effects, and dawn phenomenon.

General Studying Advice

Studying Techniques: Emphasize diverse study methods combining textbooks, notes, lecture videos, and concept maps.
Key Concepts: Learn fundamental concepts about cellular responses, inflammation, tissue repair, and immune system responses.
Focus on Core Concepts: Don't get bogged down in details, rather focus on understanding core principles of each disease process and how body functions when stressed.
Use real-world examples: Using real-world diagnoses and their breakdown into pathophysiology, clinical signs and symptoms, diagnostic tests, and treatment options to aid in understanding.
