At the arterial end of a capillary bed, blood pressure is higher than at the venous end. This pressure allows nutrients, oxygen, and other essential substances to be pushed out of the capillaries and into the surrounding tissues.
arterial end
I assume the 'puncture' is accidental. An arterial puncture is characterized by bright red blood (as opposed to darker venous blood). Arterial cuts bleed fast and forceful, often in time with the heartbeat. If that happens, get thee to an emergency room-quick!

The reason fluid leaves at the arterial end of the capillary bed and returns to the venous end of the capillary bed is the difference in hydrostatic pressure. This means the pressure against the inside of the vessel is greater that the pressure on the outside of the vessel on the arterial end and vice-versa on the venous end. Also, loss of water at the arterial end very slightly raises the oncotic pressure on the venous end, although to what degree this adds to the return of fluid to the vasculature is unknown.
Blood hydrostatic pressure.
An arterial bleed, because the blood is flowing at a high rate of speed/pressure.
Arterial PCO2 is the mean arterial pressure 20 to 26mmhg.
Arterial is a reference to the blood in the arteries, as opposed to blood in the veins.
yes
It can mean Arterial Blood Gas.
Arterial PCO2 is the mean arterial pressure 20 to 26mmhg.
