Lymphocytes. Pathogens contain certain chemicals that are foreign to the body and are called antigens. Each lymphocyte carries a specific type of antibody-a protein that has a chemical 'fit' to a certain antigen.
Carpet vs. Laminate Flooring. When looking at flooring options, carpets and laminate floors are popular choices. Their cost is usually comparable and is cheaper than solid hardwood flooring. Roughly half of new flooring sold in America every year is carpet. Laminate flooring is considered more hygienic and hypoallergenic than carpet, as it is easily cleaned, and dirt won't go unnoticed.
Unlike hardwood, laminate is also water-resistant, making it one of the best options available for damp areas and below-grade bathrooms. Installing laminate floors is a simple DIY project, even for homeowners with limited home-improvement skills -- and that means even more savings on installation costs.
