  1. What is Pathophysiology
    Is the study of how disease processes affect the function of the body.
  2. The Cell & its Structure
    1/
    a normal cell incorporates a series of structures that are designed to accomplish specific functions. Common cell structures include the nucleus, the endoplasmic reticulum, and the mitochondria.
  3. The Cell & its Structure
    1/
    • 1. The Nucleus - contains DNA, the genetic blueprint for reproduction.
    • 2. Cell Membrane - covers structures within the cell, protecting and selectively allows water and other substances into and out of the cell.
    • 3. Endoplasmic reticulum - plays a key role in synthesizing proteins.
    • 4. Mitochondria - are responsible for converting glucose and other nutrients into energy in the form of Adensoine Triphosphate (ATP) which is known as metabolism.
    • 5. Adensoine Triphosphate is essentially the cell's internally created fuel and is responsible for powering all the other cellular functions. Without ATP, many of the cell's specialized structures cannot function.
    • In order for cells to function they need: H2O, glucose and O2
