Question

Trace a drop of blood beginning in the right renal vein, until it reaches the left basilic vein at the wrist.  Before reaching its final destination, the drop of blood must first pass through the right dorsalis pedis artery.

List the final steps in a numbered format.

Answer 1

A drop of blood from the right renal vein follows the following path

1. From the right renal vein, it enters the inferior vena cava ( the right renal vein directly opens into the inferior vena cava)
2. The inferior vena cava opens up into the right atrium of the heart.
3. From the right atrium, it enters into the right ventricle.
4. From the right ventricle, it enters into the pulmonary artery.
5. From the pulmonary artery, it enters into the lung
6. From the pulmonary artery it ends into the pulmonary veins
7. The pulmonary veins enter into the left atrium
8. From the left atrium, it enters the left ventricle.
9. From the left ventricle, it enters the aorta
10. from the Aorta it enters the common iliac artery
11. From the common iliac artery, it enters the external iliac artery
12. from the external iliac artery, it enters in the femoral artery
13. From the femoral artery, it enters in the popliteal artery
14. From the popliteal artery, it enters into the anterior tibial artery
15. From the anterior tibial artery, it enters the dorsalis pedis artery
16. From the dorsalis pedis artery, it enters the dorsalis pedis vein
17. From the dorsalis pedis artery it enters into the dorsal arch.
18. From the dorsal arch it enters dorsal venous arch
19. From the dorsal venous arch it enters the anterior tibial vein
20. From the anterior tibial vein, it enters the great saphenous vein.
21. From the great saphenous vein enters the femoral vein
22. From the femoral vein it enters the external iliac vein
23. From the external iliac vein it enters into the common iliac vein
24. From the common iliac vein it enters into the inferior vena cava
25. From the inferior vena cava enters into the right atrium
26. From the right atrium it enters the right ventricle
27. From the pulmonary artery, it enters into the lung
28. From the pulmonary artery it ends into the pulmonary veins
29. The pulmonary veins enter into the left atrium
30. From the left atrium, it enters the left ventricle.
31. From the left ventricle, it enters the aorta
32. From the arch of aorta, it enter into the brachiocephalic artery
33. From the brachiocephalic artery, it enters the right subclavian artery
34. From the right subclavian artery it enters the axillary artery
35. From the axillary artery, it enters the brachial artery
36. From the brachial artery it enters the right ulnar artery
37. From the right ulnar artery, it ends the superficial palmar artery arch
38. From the superficial palmar artery arch it enters in the digital artery
39. From the digital artery it enters into the digital veins
40. From the digital veins it enters into the superficial venous arch
41. From the superficial venous arch it enters the median antebrachial veins
42. From the antebrachial veins it enters the basillic vein
