Final answer:
Most of the options listed, such as the intake of alcohol and caffeine or experiencing vomiting/diarrhea, would increase fluid output due to their diuretic effects or fluid loss. However, decreased blood pressure typically prompts the body to conserve fluid, not increase output.
Step-by-step explanation:
The subject of the question addresses how various factors influence fluid output in the human body. All options given, except one, increase fluid output. Alcohol and caffeine are diuretics that increase urine production. Specifically:
- Alcohol increases fluid output by inhibiting antidiuretic hormone (ADH) release, leading to less water reabsorption.
- Caffeine stimulates vasodilation which increases the Glomerular Filtration Rate (GFR), resulting in increased urine production.
- Vomiting or diarrhea causes loss of fluids from the body and therefore increases fluid output.
- Increased GFR, as explained, results in more fluid being filtered from the blood into the urine.
The exception in the options provided is 'Decreased blood pressure'. Generally, decreased blood pressure would lead to the body retaining fluid in an attempt to maintain blood pressure, hence this would not increase fluid output.
