We’ve updated this video. Specifically, we wanted to be clearer with our

i was thinking, if you have a septical heart defect, can’t a large blood
clot go in the opening and plug it?

Great videos…please do videos on molecular biology, biochemistry,
physiology and neurology. Those are areas that affect students adversely in
the Steps

    Thanks for the suggestion! You’re right, lots of students need help with
    those topics too. Right now we’re focused only on pathology, but we hope to
    get to those topics soon in the future.
