platelets globulins fibrinogen erythrocytes leukocytes connective plasma fibrinogen coagulation albumin men women formed elements Blood is a tissue that consists of formed elements and an extracellular matrix called The formed elements include red and white blood cells, and cell fragments called Plasma: The fibers of the extracellular matrix are actually fiber precursor molecules called Plasma consists of water, protein, nutrients, electrolytes, wastes, hormones, and gases. Plasma contains a multitude of proteins. However, three proteins predominate. contributes towards blood viscosity and helps transport lipophilic substances in the blood. , otherwise known as antibodies, help combat specific pathogens. Finally, upon activation, fibrinogen forms fibers during the process of are cells and cell fragments found in the blood. serve to transport gases in the blood. are blood cells of the immune system that combat pathogens. are cell fragments that assist in the process of blood clot…
