Lo '''calci''' es un [[element quimic]], de simbòl '''Ca''' e de [[nombre atomic]] 20. Es un element quimic essencial a la vida. Se calcula que lo calci representa entre  1,5% e un 2% del pes d'una persona, que  99% se tròba dins los [[Òs|òsses]] e la resta dins los  teissits e liquids corporals intervenent dins lo [[metabolisme]] cellular.
