Inflammatory Response I: Vascular and Cellular01:30

Inflammatory Response I: Vascular and Cellular

The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Overview
Acute Inflammation I: Inflammatory Response01:26

Acute Inflammation I: Inflammatory Response

Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
Inflammation: Introduction01:28

Inflammation: Introduction

Inflammation is a fundamental, protective biological response of vascularized tissues to cellular injury, infection, or harmful stimuli. Its primary function is to eliminate the initial cause of injury, clear necrotic cells and damaged tissue, and initiate the necessary repair processes.Cardinal SignsAcute inflammation presents with classic signs. Redness results from vasodilation and increased blood flow. Heat is due to increased metabolism and circulation. Swelling results from the...

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
Acute Inflammation III: Local and Systemic Effects01:25

Acute Inflammation III: Local and Systemic Effects

Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
