WGU D236 Pathophysiology Section 1 Lesson 2 Cellular Response and Adaptation Study Guide 2024 Study Guide: D236 Pathophysiology Section 1 Lesson 2 Cellular Response and Adaptation Essential Questions: 1. Can you describe how a patient’s body will respond to an infection? 2. Can you identify the role of DNA changes in congenital anomalies? 3. Can you explain how development is disrupted in congenital abnormalities? 4. How do the body's cellular responses and adaptations react to disruptions? Essential Question 1: Can you describe how a patient’s body will respond to an infection? a. Distinguish between innate immunity and adaptive immunity. Innate immunity is a nonspecific mechanism that defends the body immediately against all types of pathogens. The innate defensive barriers include the skin, mucous membranes, phagocytic cells, ciliated cells, and mediators of the inflammatory reaction. T lymphocytes and B lymphocytes, which have memory for specific antigens, comprise the defenses known as adaptive immunity. Adaptive immunity is developed with exposure to antigens and targets precise pathogens. Which part reacts first for during assault or infection? What are the types of defenses for innate immunity? What are the types of defenses for adaptive immunity? Innate immunity is the first line of defense. The innate defensive barriers include the skin, mucous membranes, phagocytic cells, ciliated cells, and mediators of the inflammatory reaction. T lymphocytes and B lymphocytes, which have memory for specific antigens, comprise the defenses known as adaptive immunity. b. What are a few examples of anatomical barriers that protect the body from invaders? Skin, mucus membranes c. How does the GI tract participate in innate immunity? The acidic conditions and mucous lining of the stomach and intestine protect the body from invasion of many pathogens. Pancreatic enzymes, bile, mucosal antimicrobial peptides, normal bacterial flora, and
