Inflammation, Wound Healing, Autoimmune Disorders Flashcards
The protective, coordinated response of the body to an injurious agent
Inflammation
Inflammation that occurs rapidly in reaction to cell injury, rids the body of the offending agent, enhances healing, and terminates after a short period, either hours or a few days.
Acute inflammation
Inflammation that occurs when the inflammatory reaction persists, inhibits healing, and causes continual cellular damage and organ dysfunction.
Chronic inflammation
What at the three stages of acute inflammation?
- Vascular permeability
- Cellular chemotaxis
- System responses
Immune response to tissue injury or infection experienced as heat, redness, edema, pain and loss of function.
Inflammation
What happens immediately after injury inflammation?
Brief vasoconstriction
Two examples of vasoactive cells are:
- Prostaglandins
2. Histamine
Increased _____________ allows fluids and proteins to pass from the blood into the tissue.
Capillary permeability
A multi-stage that involves circulating immune cells (neutrophils) move out of the blood vessels to the site of injury and destroy pathogens and damaged cells.
Chemotaxis
The process where neutrophils squeeze through the endothelial gap
Diapedesis
The process where neutrophils encounter bacteria, engulf them, and digest them.
Phagocytosis
Erythema-redness
Rubor
Edema-Swelling
Tumor
Heat
Calor
Pain
Dolor
Fever, Pain, General malaise (a general feeling of poor health), lymphadenopathy (swollen lymph nodes), anorexia, sleepiness, lethargy, anemia, weight loss are all signs of what?
Systemic inflammation
Chemicals that reset the hypothalamic temperature center to a high setting
Pyrogens
The type of wound healing that occurs with clear wound edges with no missing tissue
Primary intention
A surgical incision is an example of what type of wound healing?
Primary intention
The type of wound healing where there is extensive loss of tissue
Secondary intention
Granulation and fibrous tissues are needed to fill in a gap in this kind of wound healing.
Secondary intention
The type of wound healing where the wound is missing a large amount of tissue and is contaminated.
Tertiary intention
The type of wound healing where a skin graft may be required.
Tertiary intention
What is the number one cause of delayed wound healing?
Infection
Which enzyme is involves in the formation of prostaglandins association with pain and swelling?
Cox-2
Which enzyme is involves with the production of protective prostaglandins that help maintain the health of the gastric mucosa?
COX-1
Fluid that contains cells and proteins is called ______.
Exudate
Clear fluid
Serous
Sanguineous fluid
Blood
Part of the inflammatory response that causes vasodilation that helps get the blood where it needs to go.
Histamines
Elevates levels of white blood cells in the blood.
Leukocytosis
What does ESR mean?C
Erythrocytes sedimentation rate
