Final answer:
In the context of ingesting 10 cups of water, Atrial Natriuretic Peptide (ANP) would most likely be released to promote excretion of sodium and water, which decreases blood volume and pressure.
Step-by-step explanation:
Among the hormones listed, the one most likely to be released after ingesting a significant amount of water like 10 cups is Atrial Natriuretic Peptide (ANP). This hormone is secreted by cardiac muscle cells in response to stretching caused by increased blood volume or pressure. Ingesting a large volume of water would increase blood volume, prompting the release of ANP for the purpose of reducing this volume and thus lowering blood pressure. When ANP is secreted, it promotes the excretion of Na+ (sodium), which is followed by water, thus leading to diuresis, a process that reduces blood volume and pressure. The backpressure generated from increased blood volume would trigger the suppression of ADH (Antidiuretic Hormone) and aldosterone secretion because their primary functions are to conserve water in the body, which is not needed in a state of overhydration.
