Practice questions testing deep understanding of the human heart, double circulation, and blood vessels.
Q1. Humans have a "double circulatory system." Trace the exact path of a red blood cell starting from the right ventricle, passing through the lungs, and ending up in the left atrium. Why is this double system necessary for mammals?
Q2. Assertion (A): The hepatic portal vein is unique because it connects two organs without going directly back to the heart. Reason (R): The hepatic portal vein carries nutrient-rich blood directly from the small intestine to the liver, allowing the liver to process, store, or detoxify the absorbed nutrients before they enter the general circulation.
