Question

HELP!? List one possible pathway in the flow of blood from the left index finger to the right atrium of the heart?

Answer 1

The deoxygenated red blood cell travels from your finger's tissue to capillary bed to capillary to venules to superficial digital veins to radial or ulnar vein to brachial vein to subclavian to superior vena cava into the right atrium through the tricuspid valve into right ventricle, through pulmonary valve to pulmonary artery to lungs down to capillaries surrounding the alveoli where it gets oxygenated. Then, it travels back from alveoli through pulmonary veins down into left atrium, through the mitral valve, into left ventricle, and out aortic valve into the aorta and then into subclavian artery to brachial artery to radial or ulnar arteries down into the superficial digital arteries into arterioles and into the capillary bed to your finger tissue.

Answer 2

nicely done

Answer 3

yes and is there a simple way of saying that :)

Answer 4

:P there are no shortcuts to knowledge

Answer 5

ok...

Answer 6

superficial digital veins to radial or ulnar vein to brachial vein to subclavian to superior vena cava into the right atrium

Answer 7

simplicity at its best :)

Answer 8

grhh...
