The Body's first line defense acts as physical barriers, in which it functions by trapping the pathogens and blocking them from entering the body. Also, all first line defenses act the same way to all pathogens, in which they're called non-specific defense.
there are 5 ways which include: eyes - secretes tears which contain an antiseptic blood - contains platelets to clot blood and white blood cells to destroy bacteria stomach - contains hydrochloric acid which kills bacteria lungs - lined with small hairs (cilias cells) to trap dust hope it helps lol xx
it helps keep out a different variety of pathogens
True
The function of the first line of defense is to keep pathogens out of the body.
The Body's first line defense acts as physical barriers, in which it functions by trapping the pathogens and blocking them from entering the body. Also, all first line defenses act the same way to all pathogens, in which they're called non-specific defense.
The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
the body's second line of defense against pathogens is the B cells.
The integumentary system is one of the first lines of defense against infection. It provides a physical and chemical barrier against the entry of pathogens.

yes because trade barriers must protect national defense.

The first line of immune defense is the skin and mucus membranes. Skin acts as a physical barrior, blocking pathogens from entering. Mucus wihin the nasal cavity blocks some of the pathogens from entering the body. Cilia also aid in protectiong by acting as a barrior as well. There is also mucus lining the bronchial tubes, which like other mucus, blocks pathogens.
