Question

A 29-year-old female develops sepsis and, as a consequence, she experiences profound vasodilation.

a) What effect does vasodilation have on the afterload? Explain why.

b) What effect does vasodilation have on blood pressure? Explain why. How will her body try to bring her blood pressure back to homeostasis?

Be detailed in your explanation and support your answer with facts from your textbook, research, and articles from scholarly journals. In addition, remember to add references in APA format to your posts to avoid plagiarism.

Explanation / Answer

Answer a. Vasodilatation causes decrease in the afterload. Afterload is the pressure against which the left ventricle has to pump blood. This is increased by vasoconstriction and peripheral systemic resistance and decreased by vasodilatation.

Answer b. Vasodilatation causes decrease in the blood pressure of thepatient and vasoconstriction causes increase in the blood pressure of the patient. This is according to the poiseulles law, which states that increase in diameter causes decrease in the pressure in the vessels. In case of vasodilatation the barorecepter are present in the wall of blood vessels which initiates the baroreflex and tries to bring the vasoconstriction and restore the blood pressure. Exrcretory system is also involved in the homeostasis maintenance by controlling the excretion of urine concentration.
