About This Chapter
Pathophysiology Components- Chapter Summary
By the time you reach the end of this lesson, you will know all about pathophysiology components and you'll be prepared to recall this information on our lesson quizzes and chapter test. These resources are all mobile friendly too, so you can study whenever it is convenient for you. The topics covered in this chapter include:
- Difference between neoplasia, hyperplasia and hypertrophy
- Causes of physical injury such as exertion and radiation
- How bacteria releases toxins to injure cells
- How genetics, drugs and immune issues affect the health of a cell
- Ways a cell is able to identify an injury
- Difference between cell swelling and hypertrophy
- What leads to a cell's death
- Reasons why storage diseases occur in the body
1. Cellular Adaptation: Increases in Number or Size
This lesson will compare and contrast different types of cell, organ, and tissue growths. More specifically, we'll cover hypertrophy, hyperplasia, and neoplasia.
2. Types of Physical Injury to Cells
This lesson will discuss some forms of cellular injury, such as trauma, temperature extremes, and radiation, as well as why cells are damaged in these events and how that may impact your body if the damage is severe enough.
3. Cellular Injury: Infectious Causes & Their Processes
This lesson will talk about how bacteria, viruses, and parasites may contribute to or directly cause injuries and death to cells, organs, and the entire body. We will discuss exotoxins, endotoxins, and much more.
4. Other Causes of Cellular Injury
This lesson will point out some ways that the cells in our body can become injured as a result of an aberrant immune system, dietary problems, and metabolic and genetic diseases.
5. How a Cell Recognizes an Injury
Cells can suffer damage resulting from infection, trauma, or injury. When this happens, cells must decide how to respond for the good of the body. In this lesson, we'll learn how a cell recognizes injury and uses apoptosis, necrosis, and other signals to die or even kill itself.
6. The Causes and Significance of Cell Swelling
This lesson will discuss the main manifestation of cellular injury, called cell swelling. We'll delve into exactly why this occurs as well as how ATP and fatty degeneration are involved.
7. Irreversible Cellular Injury and Death: Types and Causes
This lesson will discuss the different causes and types of irreversible cell injury. Notably, we'll focus in on the different types of necrosis that may occur in the body, their causes, and what they may look like.
8. The Consequences of Intracellular Accumulations
This lesson will discuss the basic concepts of intracellular, tissue, and organ accumulations, why they may occur and what they may cause. Lipid, glycogen, pigment, iron, and protein accumulation will be covered.
9. Conversion or Decreases in Cell Type or Number
This lesson will discuss cellular changes in the body such as metaplasia, dysplasia, atrophy, aplasia, and hypoplasia. We'll talk about their meanings as well as some examples of why they may occur.
10. Causes of Cell Injury: Oxygen Deficiency
This lesson will discuss how cells may be damaged due to various causes of oxygen deficiency. We'll discuss hypoxia, anoxia, ischemia, anemia, carbon monoxide, and cyanide toxicity.
11. What is Apoptosis? - Definition, Pathway & Examples
This lesson will discuss apoptosis, giving a definition and overview of importance. It will also delve into a few of the pathways by which apoptosis occurs and give some examples of when apoptosis is induced.
12. The Causes and Significance of Tissue Swelling
This lesson will discuss the different types of swelling and growths that may appear in or on your organs and tissues. We'll cover everything from hematomas and seromas to cancer and splenomegaly.
