Vocab #1 Vocab #2 Immune System Inflammatory Response (Acute vs. Chronic) Wound Healing
100
What is inflammation?
A non specific response to injury or necrosis that occurs in a vascularized tissue. It can also be characterized by redness, heat, swelling, pain, and/or loss of function.
100
what is Fever?
"hallmark of infection"?
100
Pathogens
Viruses, bacteria, damaging proteins, parasites, and fungi are all examples of what?
100
What is Acute Inflammation?
Inflammation that occurs for seconds, minutes, or days.
100
hemostasis
What occurs right after the initial injury?
200
What is diapedesis?
the movement of blood cells through the intact cell wall of the capillaries; accompanying inflammation.
200
What is innate defense/innate immunity?
It is the nonspecific defense mechanisms that come into play immediately or within hours of an antigen's appearance in the body
200
A class of cells that can “eat up” pathogens- part of the second line of nonspecific/ innate immune response.
What are phagocytes?
200
What is Chronic inflammation?
Inflammation that occurs fur long periods of time.
200
3-21 days post injury
when does proliferation happen?
300
What is Chemotaxis?
"the movement of leukocytes"
300
What are B an T cells?
known as "memory cells"
300
Acidic oils on skin, mucus membranes, stomach acid, etc. Anything that prevents pathogens from entering the body.
What are two examples of the immune systems first line of defense?
300
What are acute causative agents?
Infections
Physical Agents
Foreign bodies
300
3= inflammatory, the proliferative phase, the remodeling phase.
How many phases are involved in the wound healing?
400
What is opsonization?
It is an immune process where particles such as bacteria are targeted for destruction by a phagocyte. This is the first step of phagocytosis.
400
What is Natural Killer Cells?
NK cell stand for
400
Nonspecific- the initial immune response that responds to all foreign substances/ pathogens in the body. Begins the production of antibodies against specific antigens. Specific- acquired, specialized and systemic cells that target specific pathogens that the body has seen before.
What is the difference between a nonspecific and a specific immunity response?
400
What is an outcome of chronic inflammation?
Tissue destruction fibrosis
400
You’re losing blood and that the physical barrier of the epidermis has been compromised.
Homeostasis being the first response to the injury, what are the two immediate threats?
500
What is lymphadenitis?
inflammation of the lymph nodes.
500
What is autoimmunity?
It is when the immune system recognizes a person's own cells as foreign and begins an immune system response that injures self tissues.
500
The MHC creates specific immunity/ antigen presenting cells.
What is the roll of the major histocompatability complex (MHC)?
500
What are chronic prominent cells?
Monocytes
Macrophages
Lymphocytes
500
Scarring
what is the long-term physical characteristic from a wound?
