arterial bleeding -blood spurts from the wound -is the most serious type of bleeding because a large amount of blood can be lost in a very short period of time -less likely to clot because blood can only clot when it is flowing slowly -flows faster than most others
venous bleeding -blood from a vein flows or steadily or gushes -flows fast & study, not like arterial bleeding
capillary bleeding -most common type of bleeding, -blood oozes from capillaries steadily but slowly -usually is not serious and can be controlled easily -this type of bleeding will most likely clot -slow, oozing bleeding
each type of blood vessel--artery,vein, or capillary-- contains blood of a different shade of red
blood vessel spasm arteries contain small amounts of muscle tissue in their walls.
clotting -special elements (platelets) in blood form a clot -clotting serves as a protective covering for a wound until the tissues underneath can repair themselves
