Human systolic pressure is 16 kPa and diastolic 11 kPa but Earth atmosphere pressure is 101.325 kPa. I don't understand why when we are hurt we bleed instead of air enter into our body. ¿How can blood be "stronger" than atmosphere pressure?

@KareemElashmawy, I found in Physics.SE Gauge pressure vs. absolute pressure. So, this means that a 16 kPa of systolic and 11 kPa of diastolic is really 117,325 kPa of systolic and 112,325 kPa of diastolic (pressure + atmospherical pressure) and this is why we can bleed (inner pressure - outside pressure = +16 kPa and +11 kPa = bleeding)?.
