Ch 9 Inflammation Lecture

These flashcards cover essential vocabulary and concepts related to inflammation and wound healing, summarizing key ideas from the lecture notes.

Innate Immunity

The immunity that an individual is born with, which reacts the same way every time to an antigen.

Inflammation

A biological response of body tissues to harmful stimuli, aimed at limiting exposure to harmful agents and initiating healing.

Acute Inflammation

A rapid inflammatory response that is self-limited and occurs in response to cell injury for hours to days.

Chronic Inflammation

A prolonged inflammatory response that can occur after an unsuccessful acute response, leading to cell damage and dysfunction.

Cardinal Signs of Inflammation

The five signs which include erythema, heat, swelling, pain, and loss of function.

Serous Exudate

A clear and watery drainage that indicates early inflammation.

Sanguineous Exudate

A type of drainage containing blood.

Purulent Exudate

A thick, yellowish drainage associated with bacterial infections, commonly known as pus.

Hemostasis

The process where platelets and various signaling molecules act to stop bleeding.

Proliferation Phase

The stage in wound healing where granulation tissue forms and new cells grow.

Primary Intention Healing

An ideal wound healing where the edges are clean and can be approximated, leading to minimal scarring.

Secondary Intention Healing

A type of wound healing that involves significant tissue loss and results in a scar.

Tertiary Intention Healing

A delayed wound healing process that requires an open wound to allow for drainage before closure.

Nutrition in Wound Healing

Adequate nutrition, particularly protein intake, is crucial for optimal wound healing.

Oxygen in Wound Healing

Oxygen is essential for tissue repair and is often enhanced through treatments like hyperbaric oxygen therapy.

Complications of Wound Healing

May include keloids, contractures, dehiscence, evisceration, strictures, fistulas, and adhesions.

Keloid

An overgrowth of scar tissue that can occur during the healing process, often more prevalent in certain ethnic groups.

Fistula

An abnormal connection between two areas of the body, such as between the rectum and bladder.

Adhesions

Internal scar tissue that forms between organs, which can lead to complications.
