Inflammatory Response: Acute swelling stage (Phase 1) This is a fundamental type of response by the body to disease and injury. It is characterized by the classical signs of pain, heat, redness, and swelling.
What are the phases of inflammatory response?
The inflammatory response has four phases: inflammatory inducers (infection or tissue damage), inflammatory sensors (mast cells and macrophages), inflammatory mediators (cytokines, chemokines, etc.) and the tissues that are affected.
What are the 5 stages of inflammation?
Clinically, acute inflammation is characterized by 5 cardinal signs: rubor (redness), calor (increased heat), tumor (swelling), dolor (pain), and functio laesa (loss of function) (Figure 3-1).
What is the main cause of inflammation in the body?
Possible Causes The most common reasons for chronic inflammation include: Autoimmune disorders, such as lupus, where your body attacks healthy tissue. Exposure to toxins, like pollution or industrial chemicals. Untreated acute inflammation, such as from an infection or injury.
What is the healing process of inflammation?
The process from inflammation to the wound healing is divided into three phases: (1) inflammation process, (2) tissue formation, and (3) tissue remodeling. The inflammation program includes cell produced related factors and immune cells infiltration.
What are the 7 stages of inflammation?
The cardinal signs of inflammation include: pain, heat, redness, swelling, and loss of function. Some of these indicators can be seen here due to an allergic reaction. The five cardinal signs are heat, pain, redness, swelling, and loss of function (Latin calor, dolor, rubor, tumor, and functio laesa).
What are the 4 main signs of inflammation?

How long does the inflammation stage last?
The wound healing process is usually characterized as four sequential but overlapping phases: haemostasis (0–several hours after injury), inflammation (1–3 days), proliferation (4–21 days) and remodelling (21 days–1 year) [1].
What are the 5 cardinal signs of inflammation?
Based on visual observation, the ancients characterised inflammation by five cardinal signs, namely redness (rubor), swelling (tumour), heat (calor; only applicable to the body' extremities), pain (dolor) and loss of function (functio laesa).
How long does the inflammatory stage last?
The inflammatory phase is the second phase in the healing cascade and since the phases overlap, it initiates with injury. The inflammatory phase lasts 4-6 days and is characterized by the presence erythema, warmth, edema and pain.
How long is the inflammation stage?
Inflammatory phase – This phase begins at the time of injury and lasts up to four days. It includes clotting of platelets and constriction of blood vessels to stop blood loss, in addition to the arrival of white blood cells to kill bacteria and naturally clean the wound site.
What are the phases of inflammation?
Understanding The 3 Phases Of Inflammation. By Erik Parkin. The body’s response to injury is called inflammation. Physical traumas such as sprain, strain, or bruise are most common, whereas injuries can also occur from bacterial or viral infections, heat, or any sort of chemical injury. Trauma causes direct damage to cells in the immediate area ...
What is the body's response to disease and injury?
Inflammation is a key part of the body’s defense system, an indispensable protective response by the body’s system of self-defense. Innumerable causes (mosquito bite, a splinter, a virus infection, a bruise, a broken bone) can trigger an inflammatory response and dispatch cells and chemicals to the site to repair the damage.
What happens to scar tissue after healing?
Signs of inflammation are absent and scar tissue starts maturing. Maturation refers to the growth of fibroblasts to fibrocytes and remodeling refers to the organization of and shrinking of collagen fibers along lines of stress. There is less new collagen formation, but an increased organization of collagen fibers, and stronger bonds between them.
What is the subacute stage of collagen?
The subacute stage is the time of healing and repair. New collagen fibers are laid down in a disorganized manner in the form of a scar and there are weak links between each fiber. This new tissue is fragile and must be handled gently as it can be easily injured.
What is needed to determine if a patient has an acute or chronic inflammatory injury?
In order to determine if the condition of the injury is in the acute, subacute or chronic inflammatory stage, an adequate case history is needed along with assessment. The assessment should include a visual scan, active muscle testing, passive range of motion testing and resisted isometric muscle tests, and palpation of the structure involved.
How long does swelling last?
Acute swelling is short-lived, lasting for only a few days. If it lasts longer, it is referred to as chronic inflammation. Chronic inflammation may last for weeks, months, or beyond.
What causes a stream of events to occur?
Trauma causes direct damage to cells in the immediate area of injury, causing bleeding. A stream of events is initiated due to bleeding that results in the inflammatory process, which promotes healing of the injured tissue.
What is the inflammatory response?
The inflammatory response is a part of your innate immune system that responds to infection and injury. In this video, you'll learn about the process of inflammation and what happens when it becomes chronic.
What is the process of inflammation?
What triggers inflammation in your body? The inflammatory process is part of the innate immune system, which means that it is non specific and responds to many types of potential threats. Any damage to your tissues can trigger inflammation.
What is inflammation in the body?
Inflammation is a nonspecific immune response that helps your body fight infections and heal tissue damage. It is part of the innate immune system because it does not respond to a specific pathogen but is instead a response to any infection or injury. When tissues are damaged, inflammatory molecules called cytokines are released to initiate the inflammatory response. This causes the classic symptoms of inflammation: pain, redness, swelling, and heat.
What is the inflammatory process that occurs when a cell is damaged by an infection?
When tissues are damaged by infection or injury, they release inflammatory molecules called cytokines. Cytokines are a very important part of the inflammatory process, and they have several effects on the cells around them.
What causes swelling and redness in the body?
Increased temperature (calor) makes it more difficult for bacteria to grow. The fluid that causes swelling (tumor) and redness (rubor) contains many white blood cells like neutrophils and monocytes that destroy microorganisms and eat up dead and damaged cells and tissues.
What are the Latin words for inflammation?
By now, you would be experiencing all of the classic symptoms of inflammation, as denoted by their Latin words and their meanings: calor (heat), dolor (pain), rubor (redness), and tumor (swelling).
What is the name of the chemical that raises the temperature of the affected area?
Cytokines called pyrogens are also released to raise the temperature of the affected area. Sometimes, your entire body temperature may go up, and you may develop a fever, depending on the severity of the infection or injury.
Inflammatory Response Definition
The immune system is a network of specialized cells and proteins that defend the body against an infection of foreign invaders or harmful stimuli. Foreign invaders are called pathogens and include bacteria, viruses, and other organisms that cause infection. One of the ways the immune system delivers protection is from innate immunity.
What Triggers an Inflammatory Response?
An inflammatory response is triggered by pathogens or harmful stimuli that enter the body. Cytokine is a type of protein made by cells of the immune system. This protein can stimulate or suppress the immune response.
What are the signs of inflammation?
This mechanism is non-specific and immediate.[1] There are five fundamental signs of inflammation that include: heat (calor), redness (rubor), swelling (tumor), pain (dolor), and loss of function (functio laesa). Inflammation can divide into three types based on the time of the process that responds to the injurious cause; acute which occurs immediately after injury and lasts for few days, chronic inflammation that may last for months or even years when acute inflammation fails to settle, and subacute which is a transformational period from acute to chronic which lasts from 2 to 6 weeks.[2]
What are the two groups of inflammatory inducers?
As an alternative, we could also divide the inflammatory inducers into two large groups, which are the infectious factors and the non-infectious factors.
What causes inflammation to occur?
Acute inflammation starts after a specific injury that will cause soluble mediators like cytokines, acute phase proteins, and chemokines to promote the migration of neutrophils and macrophages to the area of inflammation.[3] These cells are part of natural innate immunity that can take an active role in acute inflammation. If this inflammation does not resolve after six weeks, this will cause the acute inflammation to develop from subacute to the chronic form of inflammation with the migration of T lymphocytes and plasma cells to the site of inflammation. If this persists with no recovery, then tissue damage and fibrosis will ensue. Other varieties of cells, such as macrophages and monocytes, play a role in both acute and chronic inflammation. In this article, we will discuss "acute inflammation."
What are the causes of inflammatory bowel disease?
Polygenic inflammatory bowel disease (IBDs) is characterized by an excessive inflammatory response to gut microbial flora. IBDs include Crohn disease (CD) and ulcerative colitis (UC). These two diseases are cytokine driven. Apart from that, other causes include non-infectious inflammation of the bowel. The system can recognize the microbial agent through the TLRs. These PAMPs that bind to the TLRs (mainly TLR4) activate the signaling pathways (NF-kB, MAPK) that cause the production of cytokines and chemokines to start the resistance to the infection. [19]
What are mediators in the inflammatory process?
The first group of mediators is the toll-like receptors (TLRs), which are membrane-spanning proteins found on the surfaces of the innate immune system cells like macrophages and dendritic cells. These single-pass membrane-spanning receptors recognize the pathogen-associated molecular patterns (PAMPs) or can recognize endogenous signals activated during tissue or cell damage known as danger-associated molecular patterns (DAMPS). To date, research has identified more than ten TLRs. An important example is the CD14 (cluster of differentiation 14), a co-receptor for TLR4, which is present on the surface of innate immune system cells preferentially expressed in macrophages, monocytes, and neutrophils. TLR4 can recognize the Lipopolysaccharide, which is the major component of the outer membrane of the gram-negative bacteria (PAMPs). Then the transmission of PAMPs and DAMPs are mediated by MyD88 (myeloid differentiation 88) along with the TLRs. Subsequently, the signaling will transmit through a specific cascade that leads to nuclear translocation of transcription factors, such as NF-kB, activator protein-1 (AP-1), or interferon regulatory factor 3(IRF3). [7][8][9]
What causes phagosomal damage in macrophages?
Causes include allergens, toxic compounds, irritants, and foreign bodies that are too large to be digested or cause phagosomal damage in macrophages. Examples of foreign bodies include silica and asbestos.
What are the two classes of inducers?
This grouping can further subdivide into two classes; microbial and non-microbial exogenous inducers.
