Starting from the smallest, arrange the veins in the correct order to trace the return of blood from the foot towards the heart.
Understand the Problem
The question is asking to arrange various veins in the correct order based on their size, starting from the smallest, to trace the return of blood from the foot towards the heart. This involves understanding the anatomical pathways of blood flow in the venous system.
Answer
Dorsal venous arch, Saphenous vein, Femoral vein, External iliac vein, Common iliac vein, Inferior vena cava
Stage 1: Dorsal venous arch, Stage 2: Saphenous vein, Stage 3: Femoral vein, Stage 4: External iliac vein, Stage 5: Common iliac vein, Stage 6: Inferior vena cava
Answer for screen readers
Stage 1: Dorsal venous arch, Stage 2: Saphenous vein, Stage 3: Femoral vein, Stage 4: External iliac vein, Stage 5: Common iliac vein, Stage 6: Inferior vena cava
More Information
Blood returns to the heart from the foot starting at the dorsal veins in the foot, then travels upward through larger veins, finally reaching the inferior vena cava.
Tips
A common mistake is to confuse the order of veins. Remember that blood travels from smaller, peripheral veins in the extremities toward larger central veins.
