I have a close friend, who just started nursing school
. She was talking about how it is so fast paced for her, and the feeling of metal diarrhea. She posed the question of how blood flows through the heart to me, so I answered
"From the upper body through the superior vena cava, from the lower body through the inferior vena cava, into the right atrium, through the tricuspid, in to the right ventricle, through the pulmonary valve, into the pulm. artery, then to the right and left lungs for oxygenation, to the pulmonary vein to the left atrium, through the mitral, into the left ventricle, through the aortic valve into the aorta, then then on into circulation".
That was a mouthful. Anyway, she laughed and asked how could I remember something like that when there is so much more to know. And I really didn't have an answer.
So now, I'm asking you. How do you all remember those things that are at the foundation, when there is so much more for us to know? Is it just natural, have you forgotten a lot, or what? And, do you know how blood flows through the heart?
