Question

Trace a drop of blood from the left ventricle (top) to the right fingers (bottom):

Superficial palmar arch, subclavian, ulnar, digital arteries, axillary, brachiocephalic trunk, brachial, aortic arch

Answer 1

The movement of blood from left ventricle to the finger tips

The blood drop is pumped out if the left ventricle during the systole causing the movement of blood drop to the aortic arch .from the arch if aorta it moves to the brachiocephalic trunk and from the brachiocephalic trunk it moves to the right subclavian arter as it is the main artery that supply blood to the arms . From there it moves to the axillary artery which is the continuation of right subclavian. From the axillary artery it moves to the brachial artery and from there it moves to the right ulnar artery that is a division of right brachial artery. It reach the superficial palmar arch formed by ulnar and radial artery from there it reach the finger tip through the digital arteries. This is how the drop of blood reach the finger tips
