The human heart starts to beat by the 5th week of gestation (5 weeks after conception), the heart will continue to beat, up until the adult human experiences physiological death.

You have searched me, Lord,
    and you know me.
You know when I sit and when I rise;
    you perceive my thoughts from afar.
You discern my going out and my lying down;
    you are familiar with all my ways.
Before a word is on my tongue
    you, Lord, know it completely.
You hem me in behind and before,
    and you lay your hand upon me.
Such knowledge is too wonderful for me,
    too lofty for me to attain.

For you created my inmost being;
    you knit me together in my mother’s womb.
I praise you because I am fearfully and wonderfully made;
    your works are wonderful,
    I know that full well.
My frame was not hidden from you
    when I was made in the secret place,
    when I was woven together in the depths of the earth.
Your eyes saw my unformed body;
    all the days ordained for me were written in your book
    before one of them came to be.
How precious to me are your thoughts, God!
    How vast is the sum of them!
Were I to count them,
    they would outnumber the grains of sand
    when I awake, I am still with you.

â€" Psalm 139
