Answer:
If a splinter of wood enters the skin and introduces microorganisms to the site the body would first release chemical mediators like histamine then cause vasoconstriction. Platelets work to make a blood clot then neutrophils come in and vacillation occurs. This causes redness, warmth, swelling and pain. Edema and pus formation occurs therefore the neutrophils work to rid the area of cell debris and pathogens. Later the lymphocytes and macrophages will finish the job of the neutrophils and scar tissue is formed to repair the damaged tissue.
Explanation:
Soil scientists use the capital letters O, A, B, C, and E to identify the master soil horizons<span>, and lowercase letters for distinctions of these horizons. Most soils have three major horizons: the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but such a horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation). Hard bedrock, which is not soil, uses the letter R.</span>
