Upon tissue injury, damaged cells release inflammatory chemical signals that evoke local vasodilation , the widening of the blood vessels. Increased blood flow results in apparent redness and heat. In response to injury, mast cells present in tissue degranulate, releasing the potent vasodilator histamine.
How does the body respond to injury?
The body always responds to an injury with a predictable inflammatory response , as the first step towards healing. Redness, heat, swelling and pain are associated with this first stage. Redness and heat are caused by increased blood flow.
What is the name of the response to an injury?
Inflammation , a response triggered by damage to living tissues. The inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and injury.
What is local inflammatory response?
Local inflammatory response (local inflammation) occurs within the area affected by the harmful stimulus . Acute local inflammation develops within minutes or hours following a harmful stimulus, has a short duration, and primarily involves the. innate immune system. .
What is the body’s normal response to an injury?
Inflammation is the body’s normal response to injuries or infections. Cells of the immune system travel to the site of injury or infection and cause inflammation to protect and heal the area.
What does tissue damage feel like?
When soft tissue is damaged, there is usually immediate pain along with immediate or delayed swelling (excessive swelling can slow the healing process – see treatment below). Stiffness is also very common as a result of the trauma and swelling. Bruising may also develop after 24-48 hours.
How do you know if an injury is healed?
Even after your wound looks closed and repaired , it’s still healing. It might look pink and stretched or puckered. You may feel itching or tightness over the area. Your body continues to repair and strengthen the area.
What are the 3 stages of inflammation?

What is the primary damage response to injury?
Upon tissue injury, damaged cells release inflammatory chemical signals that evoke local vasodilation, the widening of the blood vessels. Increased blood flow results in apparent redness and heat. In response to injury, mast cells present in tissue degranulate, releasing the potent vasodilator histamine.
What are the 3 stages of healing?
- Inflammatory phase – This phase begins at the time of injury and lasts up to four days. ...
- Proliferative phase – This phase begins about three days after injury and overlaps with the inflammatory phase. ...
- Remodeling phase – This phase can continue for six months to one year after injury.
What are the steps of the inflammatory response?
The response to ICH occurs in four distinct phases: (1) initial tissue damage and local activation of inflammatory factors, (2) inflammation-driven breakdown of the blood–brain barrier , (3) recruitment of circulating inflammatory cells and subsequent secondary immunopathology, and (4) engagement of tissue repair ...
How is local inflammation treated?
- Heat therapy.
- Cold therapy.
- Electrical stimulation.
- Traction.
- Massage.
- Acupuncture.
What are the events of inflammatory response?
At the tissue level, inflammation is characterized by redness, swelling, heat, pain, and loss of tissue function, which result from local immune, vascular and inflammatory cell responses to infection or injury [5].
Can tissue damage be repaired?
While a few types of tissue injury (such as minor paper cuts) can sometimes be healed in such a way that no permanent damage remains, most of our tissue repair consists of both regeneration and replacement .
What is the first stage of inflammation when an injury occurs?
