Decide whether each statement about urine formation is true or false. The liver changes toxic substances into less toxic substances that then travel to the
kidneys
The kidneys filter blood and produce urine.
Urine is made from the nutrients that are reabsorbed back into the blood from the
tubules
The kidney is the functional unit of the nephron
Urine is produced in the nephrons of the kidneys
Urine that is produced in the kidneys flows down the urethra to the bladder for storage
and then is excreted through the ureters.
