What is an inflammatory response?
The inflammatory response (inflammation) occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause. The damaged cells release chemicals including histamine, bradykinin, and prostaglandins. These chemicals cause blood vessels to leak fluid into the tissues, causing swelling.
Is inflammation always an immune response?
Inflammation is a biological response of the immune system that can be triggered by a variety of factors, including pathogens, damaged cells and toxic compounds.
What are two types of inflammatory response?

Is inflammation specific or nonspecific?
Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN. Specific defenses include antibody (more…)
How does inflammation affect the immune system?
Inflammation is your body’s first line of defense against toxins, infections and injuries. When your cells are in distress, they release chemicals to alert the immune system. The immune system sends its first responders — inflammatory cells — to trap the offending substance or heal the tissue.
Is an immune response the same as immunity?
The second line of defense against non-self pathogens is called adaptive immune response. Adaptive immunity is also referred to as acquired immunity or specific immunity and is only found in vertebrates. The adaptive immune response is specific to the pathogen presented.
What is the difference between inflammation and infection?
You may hear the words infection and inflammation together, but they mean very different things. Infection refers to the invasion and multiplication of bacteria or viruses within the body, while inflammation is the body’s protective response against infection.
How many types of immune responses are there?
This protection is called immunity. Humans have three types of immunity — innate, adaptive, and passive: Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection. For example, the skin acts as a barrier to block germs from entering the body.
