Hi so I’m 16, a girl Later today I went to the doc and got my blood pressure took, it was 140/79. I was s CONCERNED! 5 hours later I took an at home blood pressure test and it says “126/80”. Can BP fluctuate? I was nervous when I went to the doc, can that be why my blood pressure was high?

The answer would be true.

1.controls blood flow2.controls oxygen flow3.carries oxygen rich blood to veins

Unlike  ct scans, which use x-rays,  mri scans  use powerful magnetic fields and radio frequency pulses to produce detailed pictures of organs, soft tissues, bone and other internal body structures.  differences between  normal and abnormal tissue is often clearer on an  mri  image than a  ct.you can see more with a mri scan. for example on an mri you can see internal bleeding.
