Final answer:
The excretion of dilute urine involves the kidneys reabsorbing less water under the influence of hormones, leading to a greater volume of urine that is less concentrated.
Step-by-step explanation:
Excretion of dilute urine requires the proper functioning of the kidneys and is influenced by the balance of water and solutes in the body. When the body is hydrated, or diuretics such as alcohol inhibit the release of ADH (antidiuretic hormone), the collecting ducts in the kidneys become less permeable to water, resulting in more water being excreted and thus, more dilute urine. This process is also influenced by the hormonal control of ion reabsorption in the Distal Convoluted Tubule (DCT) and the collecting duct, which is regulated by hormones like aldosterone and ADH. When these hormones are absent or inhibited, the kidneys tend to reabsorb less water, leading to the excretion of a larger volume of dilute urine.
