Flashcards

What is Histamine?

Histamine is a chemical messenger released by immune cells during inflammation.

How does Histamine affect blood vessels?

Histamine causes blood vessels to widen, increasing blood flow to the affected area.

What is Inflammation?

Inflammation is a complex biological response triggered by injury or infection, involving the release of chemical mediators like histamine.

Is Fever caused by histamine?

A fever is an elevated body temperature triggered by the immune system's response to infection, NOT directly by histamine.

What are IgE antibodies?

IgE antibodies are a specific type of antibody involved in triggering the release of histamine, especially in allergic reactions.

Where do T lymphocytes mature?

T lymphocytes, also known as T cells, mature in the thymus gland, but they originate from the bone marrow.

What are B and T cells?

B and T cells are both types of white blood cells called lymphocytes, which play crucial roles in the immune system.

What do Cytotoxic T cells do?

Cytotoxic T cells are specialized T cells that directly kill infected cells by releasing toxic substances.

What is the function of Suppressor T cells?

Suppressor T cells help regulate the immune system by preventing an overreaction that could harm the body.

Where are B cells produced?

B cells are produced in the bone marrow and are responsible for making antibodies, which are proteins that target specific pathogens.

What are Memory B and T cells?

Memory B and T cells are specialized immune cells that 'remember' specific pathogens they have encountered before, allowing for a faster and stronger response upon re-exposure.

How do Memory B cells protect against mumps?

Memory B cells are responsible for providing immunity against diseases like mumps, meaning they can rapidly react to re-exposure.

What is Anaphylaxis?

Anaphylaxis is a severe and potentially life-threatening allergic reaction that is primarily mediated by the release of IgE antibodies and histamine.
