    You have just been in an accident and have experienced substantial blood loss. What autoregulatory mechanisms in the kidney will be initiated to maintain filtration pressure? Describe this mechanism in detail. If blood loss continues, what will occur to the autoregulatory mechanism?

    Given the following lab values, answer the same questions addressed in question, again, give specific reasons for your answers.
    pH = 7.48; PCO2 = 46 mm Hg; HCO3- = 33mEq/L

    To put it very simply, when a person experiences a lot of blood loss the kidneys stop functioning because their main job is to remove parts of the blood. A decreased blood volume is immediately dangerous to every cell in the body because they cannot get nourishment and oxygen and cannot expel wastes. The general homeostasis of the body is disrupted. The kidney attempts to compensate for blood loss by keeping the body as full as possible, which means that they stop filtering and removing anything (including waste). The glomerulus is a very delicate structure that does not heal itself well. The injury caused by severe blood loss may cause damage that cannot be recovered.
    <br>How does this work? There are 3 types of regulation that help the glomerular filtration rate adjust to body conditions: renal autoregulation, neural regulation, and hormonal ...

    Solution Summary

    Autoregulatory mechanisms in the kidney are discussed.
