Detailed explanation-1: -Urea is produced in the liver and eliminated from the body through kidneys, from liver it travels to heart then lungs followed by heart.
Detailed explanation-2: -From the calyxes, pee travels out of the kidneys through the ureters (pronounced: YUR-uh-ters) to be stored in the bladder (a muscular sac in the lower belly). When a person urinates, the pee exits the bladder and goes out of the body through the urethra (pronounced: yoo-REE-thruh), another tube-like structure.
Detailed explanation-3: -The urea and water are released from the liver cells to the bloodstream and transported to the kidneys where the blood is filtered and the urea is passed out of the body in the urine. Urea is very soluble and a small molecule, so it is relatively easily passed out by the kidneys as a solution in water.
Detailed explanation-4: -So, the correct answer is ‘Collecting duct–>Ureter–>Bladder–>Urethra’.
