Cilia protect your body from pathogens up to a certain extent. The cilia in your lungs prevent dust particles and other such particles you breathe from entering your lungs by trapping them and sweeping them away. The cilia located on the cell membrane prevents certain substances from entering the selectively permeable cell membrane through that same manner. However, if you get a cut or something, cilia are not really going to protect pathogens from entering your body from that cut.
The integumentary system (skin) blocks the entrance of pathogens and prevents the loss of water.
The integumentary system is used as a waterproof barrier that blocks the entrance of pathogens into and prevents water loss from the body.
Tiny hairs that trap pathogens is the best definition of cilia. Cilia are hair-like structures that line the respiratory tract and help trap and remove pathogens and particles from the airways to protect the body from infection.
It doesn't.
mucous membranes, cilia
The immune system and the lymphatic system work together to protect the body from pathogens. The immune system recognizes and targets pathogens, while the lymphatic system helps circulate immune cells and remove pathogens from the body. Additionally, the skin and mucous membranes act as physical barriers to prevent pathogens from entering the body.
White blood cells ingest the pathogens to prevent them from harming the human body
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.
The ciliated epithelium is adapted for movement and protection. The cilia on the cells move in a coordinated manner to help move mucus, debris, and microorganisms out of the respiratory tract. Additionally, the mucus secreted by this epithelium helps to trap pathogens and prevent them from entering the body.
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.
The pores on your skin help to prevent harmful pathogens from entering. Pathogens cause disease, infection and Cancer. By keeping these pathogens out, this is how pores protect you.
