the three lines of defense your body has against disease include all except

A: physical and chemical defence's
B: inflammation
C: immune system
D : scarring

First: Scarring

Scarring has nothing to do with defense

Second: False
Its B and T cells (lymphocytes)

Third: B cells
B cells produce antibodies

I think D, but what do you think?

is 100% correct

To identify the line of defense that is excluded among the given options, you must understand the three lines of defense that the body utilizes to protect itself against disease:

1. The first line of defense is the body's physical and chemical barriers, which act as a physical boundary to prevent the entry of foreign substances. This includes the skin, mucous membranes, and various secretions like saliva, tears, and stomach acid.

2. The second line of defense involves inflammation, which is the body's response to tissue damage or infection. It is characterized by redness, swelling, heat, and pain. Inflammation helps to contain the infection or injury and to recruit immune cells to the affected area.

3. The third line of defense is the immune system, which is responsible for recognizing and eliminating specific pathogens or foreign substances. This involves the activation of immune cells, production of antibodies, and coordination of immune responses.

Now, looking at the given options:

A: "Physical and chemical defense's" - This option is correct as it represents the first line of defense.

B: "Inflammation" - This option is correct as it represents the second line of defense.

C: "Immune system" - This option is correct as it represents the third line of defense.

D: "Scarring" - This option is not part of the three lines of defense. Scarring refers to the formation of scar tissue during the healing process but does not actively protect against diseases.

Therefore, the correct answer is option D: scarring, as it is the line of defense that is excluded among the given options.
