4
What is Hypertrophy?
Enlarged Cells/Organelles
5
What is Hyperplasia?
More Cells
6
What is Atrophy?
Cell Shrinkage or Loss?
7
What is Cachexia?
Fatty atrophy that can result in death (about 68% of normal body weight)
8
What is Metaplasia?
Replacement of one cell type by another.
9
What is Dysplasia?
Disordered Hyperplasia without maturation. (risk of tumor)
10
What cells are most prone to injury?
-High metabolic activity (Cardiac myocytes, hepatocytes)
-Rapidly Proliferating (Intestinal Epithelium, Testicular germ cells)
11
What are the degrees of Cell Injury?
Reversible - Damage not enough to kill cell
- Toxic liver injury, Severe exercise
Irreversible - Cell death
- via holes in membrane, mitochondrial loss.
12
What are the 2 types of Irreversible Cell Death?
Necrosis (uncontrolled)
Apoptosis (Programmed Cell Death)
13
What is apoptosis?
Programmed cell death.
- No inflammation
- One cell at a time
14
What is Necrosis?
Uncoordinated cell death
- happens in cell clusters
-Incites Acute inflammation
-Cells are often swollen (loss of ion pumps)
15
What are the different types of Necrosis?
Coagulative - Heart Infarct
Liquefactive - Brain
Fat
Caseous - Tuberculosis
Gangrenous - Frostbite
16
Examples of Abnormal Storage Products...
Fatty
Glycogen
Lipid
Brown Storage
Protein
Calcification
17
Example of Fatty Abnormal Storage...
Alcohol induced Fatty-Liver
Obesity
18
Example of Glycogen Abnormal Storage...
Liver in Diabetes
Certain tumors
19
Example of lipid Abnormal Storage...
Vessels in atherosclerosis
Fabry's or Gaucher's
20
Example of Brown Abnormal Storage...
Lipofuscin - degraded lipid in lysosomes
Bilirubin
Hemosiderin - Iron Containing pigment (bleeding into tissues)
21
Example of Protein Abnormal Storage...
Intracellular - Alpha-1-antitrypsin deficiency, Russell Bodie
Extracellular - Amyloid Plaques (Congo Red Stain = Apple green color in polarized light)
22
Examples of Miscellaneous abnormal storage...
Anthracosis (Silica, asbestos)
23
Example of Calcification Abnormal Storage...
Dystrophic - into damaged tissue
Metastatic - Into normal tissue (renal failure, hypoparathyroidism, malignancy)
24
What is edema?
Too much extravascular fluid in tissues.
25
What is Effusion?
Too much fluid in a body cavity.
26
What is Ascites?
Excess fluid in peritoneal space.
27
What is hypotension?
Shock/Low-blood pressure
- Hypovolemic (Blood)
- Cardiogenic (Heart)
-Sepsis (generalized infection)
28
What is Congestive Heart Failure?
Insufficient cardiac output from...
systolic dysfunction (Weak pumping)
Diastolic dysfunction (insufficient expansion)
29
What is the bodies compensation for CHF?
Tachycardia
Cardio Hypertrophy
Increased Stroke Volume (Frank-Starling)
Increased catecholamine activity
Redistribution of blood flow
