How many times does a molecule of urea have to pass through the heart in its journey from liver to kidney?
Options:
Answer:
C
Solution:
Urea produced by the liver will come out of the liver through a hepatic vein, then it will enter the heart through the inferior vena cava. From the heart, it will enter the lungs through pulmonary arteries. Urea will then return to the heart through pulmonary veins. It will then reach the renal artery through the aorta. In this process, urea passes through the heart twice.
