The healing Process Flashcards
Signs of Inflammation
Redness Swelling Tenderness Increased Temperature Loss of Function
What does Histamine do in the inflammatory process
Causes vasodilation and increased cell permeability
What do Leukotrienes do
Responsible for Margination in which leukocytes adhere along the cell walls
What helps the formation of a clot
The conversion of fibrinogen to fibrin
Inflammatory response sequence
Injury to cell Chemical mediators liberated Vascular reaction Platelets and leukocytes adhere to vascular wall Phagocytosis Clot formation
When does chronic inflammation occur
WHen the acute inflammation response doesnt respond sufficiently
Macrophages
Phagocytic cells of the immune system
Lymphocytes
Cells that are the primary means of providing the bodyt with immune capabilities
Chronic inflammation involves the production of ____ tissues
granulation and fibrous connective tissues
Fibroblastic Repair Phase
Activity leading to scar formation and repair of the injured tissue follows the inflammation phase
Fibroplasia
Begins within the first few days after injury and may last for as long as 4-6 weeks
During the repair phase what grows and how
Endothelial capillary buds by the lack of oxygen
Formation of granulation tissue occurs with the breakdown of ____
Fibrin Clot
What does granulation tissue consist of
Fibroblasts
Collagen
Capillaries
ON the 6th or 7th day fibroblasts begin producing ____
collagen fibers
Type I collagen is found in
Skin Fasciae Tendon Bone Ligaments Cartilage Intersitial tissue
Type II collagen is found in
Hyaline Cartilage
vertebral disks
Type III collagen is found in
skin
smooth muscles
nerves
blood vessles
During the maturation phase type ___ collagen decreases and type ___ collagen increases
III
I
Wolff’s Law
bone and soft tissue will respond to the physical demands placed on them
