B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.

The Epcot ball is a 165-ft diameter geodesic sphere that is elevated above the ground to stand 180 feet tall. Each face of the polyhedron is divided into three isosceles triangles to form each point. In theory, there are 11,520 total isosceles triangles forming 3840 points. Some of those triangles are partially or fully nonexistent due to supports and doors; there are actually only 11,324 silvered facets, with 954 partial or full flat triangular panels.
