Bleeding Chpt. 23 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 muscles 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 opening in injured blood vessels and stop blood flow
Coagulation
A bruise, or ecchymosis
Contusion
Discoloration of the skin associated with a closed wound; bruising
Ecchymosis
A nosebleed
Epistaxis
Vomited blood
Hematemesis
He•ma•tem•e•ses
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
He•mop•ty•ses
Bleeding
Hemorrhage
A condition that occurs when the level of tissue per fusion decreases below that needed to maintain normal cellular function, also called shock
hypoperfusion
A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, result in inadequate perfusion
Hypovolemic shock
Black, foul-smelling, tarry stool containing digest blood
Melena
Circulation of blood within an organ or tissue in adequate amounts to meet the current needs of the cellls
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
Vasoconstiction
The blood vessels that carry blood from the tissues to the heart
Veins
Very small, thin-walled vessels
Venules
