How does the body build resistance to certain pathogens? by getting antibiotics for an infection

by forcing the pathogens out of the body

by producing macrophages when the body encounters an antigen

by exposure to pathogens, or having a certain disease

Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. Cytokines such as interferons are molecules that signal neighboring cells and induce an antiviral state in them. These cells are then primed to resist an infection with the invading virus.

Explanation:

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
