Answer 1

A human blood cell survives in circulation for about 115 days. After it dies the remains of the dead cells get excreted as waste, finding their way into both your urine and poo.

The body also constantly monitors how much blood you have so if you are low on blood (such as by donating or bleeding) then your body will temporarily increase the production of blood to catch up and restore you to normal.
