Final answer:
When Lisa consumes an excess amount of salt, her body regulates water levels, increases blood pressure, and retains sodium and water to maintain normal blood pressure.
Step-by-step explanation:
When Lisa consumes an excess amount of salt, her body responds to maintain blood pressure through various mechanisms. One important mechanism is the role of the kidneys. The kidneys adjust the water level in the body by retaining water and increasing blood pressure. They produce angiotensin, a protein that constricts blood vessels and signals the body to retain sodium and water. This helps restore normal blood pressure.
Additionally, when there is excessive sodium intake, it raises blood pressure, which is a common risk factor for stroke, coronary heart disease, and kidney disease. To counteract these risks, it is recommended to curb salt intake and consume beverages and food with less sodium.
Overall, Lisa's body responds to excess salt by regulating water levels, increasing blood pressure, and retaining sodium and water to maintain normal blood pressure.
