The body's first line of defense, consisting of physical barriers and immune cells.

Immune response that develops over time with specific targets; involves memory.

An exaggerated immune response causing tissue damage.

Immune system mistakenly attacks the body's own cells.

Immediate allergic reaction mediated by IgE antibodies.

Antibody-mediated destruction of cells through complement activation.

Immune complexes form and promote inflammation; not tissue-specific.

Delayed reaction mediated by T cells and macrophages.

Severe, life-threatening allergic reaction requiring immediate treatment.

An autoimmune disorder that results in hyperthyroidism.

Autoimmune condition affecting nerve signaling to muscles, leading to weakness.

Condition where maternal antibodies attack fetal red blood cells, leading to anemia.

Immunoglobulin involved in allergic reactions.

A medication used to treat severe allergic reactions like anaphylaxis.

Widening of blood vessels that increases blood flow and can cause redness and swelling.

Immune cells that target non-self cells for destruction.

White blood cells that are the first responders to infection, targeting microorganisms.

Large immune cells that engulf and digest cellular debris and pathogens.

T cells that kill infected or cancerous cells directly.

Lymphocytes that produce antibodies to neutralize pathogens.

Long-lived B cells that remember past infections for quicker responses.

A state where the immune system's ability to fight infections is weakened.

Condition where the immune system attacks the body's own tissues.

A delayed reaction causing inflammation from skin contact with an allergen.

When recipient antibodies attack donor red blood cells in a transfusion.

A chemical released during allergic reactions, causing symptoms like vasodilation.

Reaction mediated by T cells occurring 48-72 hours after exposure.
