Mаtch the fоllоwing cellulаr аnd chemical agents оf inflammation to the correct description: selectins class of small proteins produced by WBCs; have autocrine, paracrine, and endocrine roles in cellular communication heparin produced by basophils and mast cells, stimulates vasodilation and capillary permeability colony-stimulating factor promotes cell death by apoptosis; slow tumor growth by damaging their vessels platelets plasma clotting protein; activated forms sticky mesh, sequesters pathogens forms temporary scaffold for tissue rebuilding cytokines hormones that raise WBC count by leukopoiesis fibrinogen eicosanoid secreted by basophils and mast cells activate and attracts neutrophils and eosinophils histamine polysaccharide secreted by basophils and mast cells inhibits tissue fluid coagulation promoting free mobility of WBCs leukotrienes rebuild damaged tissue by releasing collagen fibers and ground substance tumor necrosis factor cell-adhesion molecules of endothelial cells, adhere to WBCs, promoting margination and diapedesis fibroblasts secrete clotting factors and growth factors aid in preventing hemorrhage
