What does debridement mean?
Removal of devitalized tissue and contaminants
What does approximated mean?
Returned to proximity; brought together sides or edges
What does autologous mean?

capillary tube or absorbent material to rise or fall as a result of surface tension
What are chronic wounds?
Wound that persists for an extended period of time
What does cicatrix mean?
A scar
What is collagen?
Protein that consists of bundles of reticular fibers that form the white, inelastic fibers of fascia, ligaments, and tendons
What does compress mean?
To apply pressure
What is dead space?
A space that remains in the tissues as a result of failure of proper closure of a surgical wound
What is edema?
The abnormal accumulation of fluid in the interstitial spaces of tissues causing swelling
What is elasticity?
The ability of tissue such a skin, lungs, or muscles to return to its normal shape after being pushed inward, stretched outward, or in some way manipulated
What is evisceration?
Interruption of a closed wound or traumatic injury that exposes the viscera
What does exudate mean?
Mass of cells and fluid that
has seeped out of blood vessels or an organ, especially in inflammation
What does first intention mean?
Type of healing that occurs with primary union that is typical of an incision opened under ideal conditions; healing occurs from side to side, dead space has been eliminated, and the wound edges are accurately approximated
What is the French-Eye Needle?
A type of needle in which the suture must be threaded by pulling the strand through a V-shaped area into the eye. Does most damage
What does friable mean?
Easily torn or crumbled
What does gangrene mean?
Necrosis of tissue usually due to ischemia and subsequent bacterial infection
What is granulation?
Second intention wound healing in which the wound is left open to heal and the space is filled in from the bottom upward with granulation tissue
What is hemolysis?
The destruction of erythrocytes
What is hemostasis?
The arrest of the escape of blood through natural or artificial means
What is a hemostat?
