What factors influence the reabsorption of substances like glucose and water in the kidneys, and how is urine transported from the kidneys to the bladder?

Reabsorption of substances in the kidneys is influenced by factors such as excess water in the body and the amount of dissolved waste. Urine formed in each kidney is transported to the bladder through the ureter, and the bladder, being muscular and under nervous control, allows controlled release through the urethra.
