Which of the following best describes an example of a nonspecific internal response to harmful bacteria?

Skin serves as a physical barrier that prevents bacteria from entering the body.

Saliva contains enzymes that destroy bacteria and prevent infection.

Antibodies recognize and destroy antigens, which prevents bacterial infections from occurring.

Bacterial infection causes the release of histamine, which leads to inflammation and swelling.

Skin responds to external bacteria, therefore this is wrong.
Saliva contains lysozyme, an enzyme and targets all bacteria, but is produced constantly and is therefore not a response.
Antibodies do this, but to do this they have to target the bacterial antigens specifically. This is specific.
Swelling leads to increased blood flow to the area and more immune cells in the infected area. This is both non-specific and internal.

Fun Fact! Skin is actually your best non-specific defense against most every bacteria! There are no bacteria that can break your skin barrier and it therefore is your best non-specific, external defense.
