Final answer:
A person with a renal abnormality may have hypertension due to the kidneys' role in regulating blood pressure. Renal abnormalities can result in a loss of effective vascular volume control, leading to hypertension and other complications.
Step-by-step explanation:
A person with a renal abnormality may have hypertension in some cases due to the role that the kidneys play in regulating blood pressure. The kidneys release a protein called angiotensin which constricts blood vessels and signals the body to retain sodium and water, helping to restore normal blood pressure. If the kidneys are not functioning properly, they may not be able to regulate blood pressure effectively, leading to hypertension.
Furthermore, renal abnormalities can result in a loss of effective vascular volume control, leading to hypotension or hypertension. This can have serious consequences such as stroke, heart attack, and aneurysm formation.
