Antibull

Complement

Macrophage

2. Which of the following is part of the body's "first line of defense" against disease?

Macrophages

Skin

T lymphocytes

Antibodies

Cellular defenses, even generalized ones like macrophages, help to protect the body after a pathogen has invaded. Skin and mucous membranes block entry of pathogens.
