Microbiology Midterm Study Guide CH. 1-3 CHAPTER 1 • Cell Division Understand the process and stages of cell division in which one cell divides into two identical daughter cells. • Mitosis (Eukaryotic Cells) • Process: A eukaryotic cell divides to produce two identical daughter cells. • Purpose: To generate genetically identical cells for growth, repair, or maintenance. • Features: • Each daughter cell receives an exact copy of DNA. • Maintains chromosome number (diploid to diploid). • Role of Inflammation in Immune Response Inflammation is a key part of innate immunity, the body's natural defense present at birth. It operates as follows: 🛡️ Purpose and Process • Triggered by: Widening of blood vessels. • Key actions: • Infiltration of the infected site by antibodies and white blood cells (WBCs). • These immune cells work together to destroy invading microbes. • Causes redness, swelling, and pain—classic signs of inflammation. ⚔️ How It Supports Immunity • Kills microbes directly. • Initiates symptoms that isolate infection. • Signals the adaptive immune response, calling in specialized cells like T and B lymphocytes. This early alert system isolates danger and re...
