heart
arterial end
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.
Blood hydrostatic pressure.
This would be arterial bleeding - bright red pertains to oxygen-rich blood and the squirting is because of the pressure from the heart. Venous blood will appear dark, and oxygenated blood from the arteries will appear bright red in color.
I've been seeing the answer as "hydrostatic pressure" on other websites, but I am pretty sure it is Blood Pressure. I hope I was able to help :/
capillary blood has a really bad smell to it and arerial blood its bright red and is a heavy flow > hope i helped lol (:
Arterial pressure
Yes, blood pressure is a measure of the pressure exerted on your arterial walls as the heart pumps blood throughout the body (systolic) over the pressure when your heart is relaxed (diastolic).
blood is never blue but arterial blood lacking oxygen is darker... venous blood is dark red arterial blood is bright red capillary blood is brick red

Because being closer to the beating of the heart, it has more pressure behind it. Arterial blood is "outboud". Venous blood is "inbound".ANS2:Arterial bleeding is difficult to control because the pulsing pressure, delivered directly from the heart, makes clot formation less effective for staunching the flow than it would be for capillary or venous bleeding.
