Vocab #1 | Vocab #2 | Immune System | Inflammatory Response (Acute vs. Chronic) | Wound Healing |
---|---|---|---|---|
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.
|
what is Fever?
"hallmark of infection"?
|
Pathogens
Viruses, bacteria, damaging proteins, parasites, and fungi are all examples of what?
|
What is Acute Inflammation?
Inflammation that occurs for seconds, minutes, or days.
|
hemostasis
What occurs right after the initial injury?
|
What is diapedesis?
the movement of blood cells through the intact cell wall of the capillaries; accompanying inflammation.
|
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
|
A class of cells that can “eat up” pathogens- part of the second line of nonspecific/ innate immune response.
What are phagocytes?
|
What is Chronic inflammation?
Inflammation that occurs fur long periods of time.
|
3-21 days post injury
when does proliferation happen?
|
What is Chemotaxis?
"the movement of leukocytes"
|
What are B an T cells?
known as "memory cells"
|
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?
|
What are acute causative agents?
Infections
Physical Agents Foreign bodies |
3= inflammatory, the proliferative phase, the remodeling phase.
How many phases are involved in the wound healing?
|
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.
|
What is Natural Killer Cells?
NK cell stand for
|
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?
|
What is an outcome of chronic inflammation?
Tissue destruction fibrosis
|
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?
|
What is lymphadenitis?
inflammation of the lymph nodes.
|
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.
|
The MHC creates specific immunity/ antigen presenting cells.
What is the roll of the major histocompatability complex (MHC)?
|
What are chronic prominent cells?
Monocytes
Macrophages Lymphocytes |
Scarring
what is the long-term physical characteristic from a wound?
|
