Wow you don't know? Look it up on a book and get a life. Lol just kidding around. They are your skin, tears, saliva, earwax, and mucus. Oh and sorry about the joke I didn't mean to say it.
The immune system is the body's defense mechanism against harmful pathogens and chemicals. It includes various components such as white blood cells, antibodies, and the lymphatic system that work together to identify and eliminate foreign invaders. Additionally, physical barriers like the skin and mucous membranes also play a role in preventing the entry of pathogens into the body.
Nitrile gloves are the most effective in protecting hands against hazardous chemicals, including solvents, oils, and acids. They provide a good level of resistance and durability, making them a popular choice in laboratory and industrial settings. It's important to ensure the gloves are chosen based on the specific chemicals being handled to ensure proper protection.
it is a chemical barrier because it produces tears that are chemicals. also- for your information, skin is a physical barrier along with the nose and mucus and cilia. sebum and stomach acid are chemical. :D
A chemical fume hood provides a safe environment for working with hazardous chemicals by containing and removing fumes, vapors, and gases. It helps protect laboratory personnel from exposure to harmful substances and maintains a clean workspace.
Yes, some chemicals found in matter can be harmful to human health and the environment. It's important to understand the potential risks associated with different chemicals and take necessary precautions to minimize exposure. Government regulations and guidelines are in place to help protect against harmful chemical exposure.
Nitrile gloves are a good option for protection against gasoline and alcohols as they are resistant to many chemicals and provide good pliability. Neoprene gloves could also provide similar protection and flexibility, but may be less resistant to certain chemicals compared to nitrile gloves. It is important to always check the specific glove material's compatibility with the chemicals you will be working with.
True. The skin acts as a physical barrier and provides the first line of defense against invasion by pathogens, preventing them from entering the body.
The immune system is a network of cells tissues organs and chemicals that fight pathogens. This is how the body keeps healthy and defends against invading illnesses.
The skin protects against pathogens, however a disorder can always find a way in.
the white blood cell protects the body against invading pathogens.
a diseas that can be passed from one living thing to another is an infectious disease
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.
Because the skin protects you. It 'keeps out the dirtybugs' as my grandma likes to say.
The outermost layer of skin, called the epidermis, protects the body from the external environment. It acts as a barrier against harmful substances, pathogens, and UV radiation.
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 skin and mucous membranes provide living things with physical and chemical barriers against invasion of microbes. These membranes are part of the immune system.
Yes, sebaceous glands are accessory structures of the skin. They produce sebum, which protects the skin and produces the acid mantle that provides protection against pathogens.
the lincosamindes, clindamycin and lincomycin, which are highly active against anaerobic pathogens
