Question
during the scan with metoprolol? 4. At the bifurcation of the femoral artery, the pressure is 100 mmHg. The pressure in the veins draining either the left or right femoral artery is 10 mmHg. The resistance in the right femoral artery is 1.67 times the resistance through the left femoral artery. The total flow at the bifurcation is 800 mL min- How does the flow divide into the left and right femoral arteries? (Hint: what is the conservation of flow? Use this to solve one of the resistance values.)Explanation / Answer
According to the law of conservation of the flow, flow to the vessel is decided by resistance of the vessel. In the given question there is equal venous pressure on right and left femoral artery, so flow will be decided by resistance of the blood vessel.
Since flow is inversely proportional to resistance. And resistance in the right femoral artery is 1.67 times that of left femoral artery. Total flow to the bifurcation is 800 units. So the flow in the right femoral artery will be 1.67 times less than that of left femoral artery. By this we get,
Flow to right femoral artery will be 500 units and flow to left femoral artery will be 300 units. Unit of flow is ml per minute.
