which of the following body structures protects against disease by trapping pathogens?
The mucous membranes lining the nose, mouth, lungs, and urinary and digestive tracts provide another nonspecific barrier against potential pathogens. Mucous membranes consist of a layer of epithelial cells bound by tight junctions.

How are dirts and bacteria prevented from entering the alveolus?
Dirt and bacteria are prevented from entering the alveoli primarily through the actions of the respiratory epithelium, which is lined with cilia and mucus. The cilia move in a coordinated manner to trap and expel particles and pathogens from the airways. Additionally, the mucus serves as a barrier, trapping foreign substances, while immune cells within the respiratory system help to neutralize any pathogens that may enter. This combination of physical and immune defenses protects the delicate alveolar structures from contamination.
Can most pathogens pass through mucous membranes easily?
No, most pathogens do not pass through mucous membranes easily. Mucous membranes act as a barrier to protect the body from pathogens by trapping them and preventing them from entering the body. However, some pathogens have evolved mechanisms to breach this barrier and cause infections.
What does the nose shoot at the dust that enters his nose in osmosis Jones?
In "Osmosis Jones," the nose shoots mucus at the dust that enters, trapping it to prevent it from entering the body. This is part of the body's defense mechanisms to filter out harmful particles and pathogens. Mucus helps keep the respiratory system clean and protects against infections.
How does mucus help to clean up the air we breathe in?
Mucus plays a crucial role in cleaning the air we breathe by trapping dust, allergens, and pathogens. As air passes through the respiratory tract, mucus captures these particles, preventing them from reaching the lungs. Cilia, tiny hair-like structures on the surface of respiratory cells, then move the mucus upward toward the throat, where it can be swallowed or expelled. This process helps maintain clear airways and protects the respiratory system from irritation and infection.
Which structure represents the body's first line of defense against inflection?
The body's first line of defense against infection is primarily represented by the skin and mucous membranes. The skin acts as a physical barrier, preventing pathogens from entering the body, while mucous membranes line various cavities and secrete mucus, trapping pathogens and facilitating their removal. Additionally, secretions like saliva, tears, and stomach acid provide chemical defenses against pathogens. Collectively, these structures form a crucial initial defense against infections.
How does Mucus serves as a nonspecific defense to pathogens by?
Mucus serves as a nonspecific defense to pathogens by trapping them as they try to enter the body through the respiratory or digestive system. The mucus contains enzymes and antibodies that help neutralize and eliminate pathogens, preventing them from causing infections. Additionally, the cilia in the respiratory tract help move the mucus and trapped pathogens out of the body.
Which lymphoid organ and tissues filter pathogens from the blood?
A pair of kidneys clean waste from your body through urine.
What is the function of the fine hairs and tiny wax producing glands of the external auditory canal?
it protects the ear by trapping dust and other foreign substances
How many lip-like structures in Rheo discolor leaf using the LPO?
There are two lip-like structures on the Rheo discolor leaf that are visible using the LPO. These structures are important for trapping insects that are attracted to the plant.
How is the nose the first line in defense?
The nose serves as the first line of defense by filtering and trapping airborne pathogens, dust, and allergens through its mucous membranes and fine hairs called cilia. These structures help prevent harmful particles from entering the respiratory system. Additionally, the nasal passages contain immune cells that can initiate an immune response against pathogens. This filtering and immune activity play a crucial role in protecting the body from infections and maintaining overall respiratory health.
Which is a specific immune response?
making antibodies
Why do down feathers keep a bird warm?
Feathers are efficient structures for trapping air. Motionless air is a very good thermal insulator.
