What function does the skeletomuscular system perform to help defend the body?
What are two functions the integumentary system performs to help defend the body?
What function does the immune system perform to help defend the body?
Which body system represents your 1st line of defense against disease? How?
The body’s defense system works to prevent foreign substances that might cause disease
from entering the body. Such substances are known as pathogens. Give an example of a
pathogen.
