Trace a drop of blood from the heart to the right arm?

Answer 1

In tracing a drop of blood from the pulmonary to radial artery, there are 5 circulatory points. Pulmonary follows through to the subclavian artery, axillary artery, brachial artery, and then to the radial.

Answer 2

A drop of blood is a rather large unit to speak of here, as the capillaries are very fine vessels. Once the blood reaches the arterial capillaries it moves over into the venous capillaries, from there to the veins of the thumb, from there via either the cephalic or the basilic veins of the arm to the subclavian vein on the left and to the superior vena cava, to the right atrium of the heart, through the tricuspid valve to the right ventricle, through the pulmonary arteries to the lungs where the blood gets oxygenated.

From the lungs via the pulmonary veins to the right atrium of the heart through the mitral valve to the left ventricle, then through the aorta to the brachiocephalic trunk on the right, to the right subclavian, axillary and then brachial artery, then through either the radial or ulnar arteries to the arterial arches of the hand and then to the digital artery of the thumb.

You should really do your own anatomy assignments :P

Answer 3

• Heart-->Arch of Aorta-->Brachiocephalic-->Subclavian Artery-->Axillary Artery (which itself branches off into the Superior Thoracic Artery, Lateral Thoracic Artery, Thoracoacromial Artery, Posterior Circumflex Artery, Anterior Circumflex Artery, Subclavian Artery, etc. each with their own respective branches)-->Brachial Artery-->Ulnar Artery, Radial Artery, Deep Artery of the Arm, Ulnar Collateral Arteries (Superior and Inferior)
