The blessing of Asher Yatzar is recited by Orthodox Jews after exiting the bathroom, upon completion of any bodily functions. The prayer thanks God for the workings of the human body, and is intended to make us stop and think about the complex mechanisms that are our bodies.

Hebrew transliteration:

Baruch A-ta Ado-nay Elokeinu Melech Ha-Olam; asher yatzar et ha-Adam be'chachma, u-bara bo nekavim nekavim, chalu-lim chalu-lim, gah-luy ve'Ya-dua lifnay kisay k'vode-cha, She-Im yi-satem echad may-hem, Oh im yi-pa-tayach echad mayhem, Ee efshar le-hit-kayem ah-filu sha-ah achat. Baruch A-ta Ado-nay, Rofeh kol ba-sar u-maflee la-asot.
English translation:
Blessed are you, Ha-shem, our God, King of the universe, who formed man with wisdom and created him with many openings and hollows. It is obvious and known before Your Throne of Glory that if one of them were to be blocked or one of them were to be ruptured it would be impossible to survive and stand before You (even for a short period of time). Blessed are You, Hashem, who heals all flesh and acts wondrously.
