Final answer:
Alcohol increases blood pressure, making it harder for the circulatory system to function and putting strain on bodily organs like the liver and kidneys.
Step-by-step explanation:
Alcohol makes it more difficult for your circulatory system to move blood around your body by increasing your blood pressure. When blood pressure is high, the heart must work harder to pump blood through the arteries, which can lead to a variety of health issues, including kidney disorders and kidney failure. Moreover, heavy drinking can overload the liver, an organ essential to the excretory system, which also increases blood pressure and exacerbates the strain on the circulatory system.
