Chapter 25: Bleeding Flashcards
The main artery that receives blood from the left ventricle and delivers it to all the other arteries that carry blood to the tissues of the body
aorta
the smallest branches of arteries leading to the vast network of capillaries
arterioles
A blood vessel, consisting of three layers of tissue and smooth muscle that carries blood away from the heart
artery
The small blood vessels that connect arterioles and venules; various substances pass through capillary walls, into and out of the interstitial fluid, and then on to the cells
capillaries
The formation of clots to plug openings in injured blood vessels and stop blood flow
coagulation
a bruise, or ecchymosis
contusion
discoloration of the skin associated with a closed would; bruising
ecchymosis
a nosebleed
epistaxis
vomitted blood
hematemesis
A mass of blood in the soft tissues beneath the skin
hematoma
A congenital condition in which the patient lacks one or more of the blood’s normal clotting factors
hemophilia
coughing up blood
hemoptysis
bleeding
hemorrhage
A condition that occurs when the level of tissue perfusion decreases below that needed to maintain normal cellular functions; also called shock
hypoperfusion
A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion
hypovolemic shock
black, foul-smelling, tarry stool containing digested blood
melena
circulation of blood within an organ or tissue in adequate amounts to meet the current needs of the cells
perfusion
a point where a blood vessel lies near a bone
pressure point
A condition in which the circulatory system fails to provide sufficient circulation so that every body part can perform its function; also called hypoperfusion
shock
The bleeding control method used when a wound continues to bleed despite the use of direct pressure and elevation; useful if a patient is bleeding severely from a partial or complete amputation
tourniquet
narrowing of a blood vessel, such as with hypoperfusion or cold extremeties
vasoconstriction
The blood vessels that carry blood from the tissues to the heart
veins
very small, thin-walled vessels
venules
