-
The smallest branches of arteries leading to the vast network of capillaries
Arterioles
-
To form a clot to plug an opening in an injured blood vessel and stop bleeding
Coagulate
-
Very small, thin-walled vessels
Venules
-
A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of blody water, results in inadequate perfusion.
Hypovolemic shock
-
The blood vessels that carry blood from the tissues to the heart.
Veins
-
Coughing up blood
Hemoptysis
-
Bruising or discoloration associated with bleeding within or under the skin
Ecchymosis
-
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
-
Circulation of blood within an organ or tissue in adequate amounts to meet the current needs of the cells
Perfusion
-
Black, foul-smelling, tarry stool containing digested blood
Melena
-
-
-
A mass of blood in the soft tissues beneath the skin
Hematoma
-
Vomited blood
Hematemesis
-
A congenital abnormality in which the body is unable to produce clots, which results in uncontrollable bleeding.
Hemophilia
-
A blood vessel, consisting of three layers of tissue and smooth muscle that carries blood away from the heart.
Artery
-
Narrowing of a blood vessel, such as with hypoperfusion or cold extremeties
Vasoconstriction
-
A condition in which the circulatory system fails to provide sufficient circulation to enable every body part to 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
-
The small blod vessels that connect arterioles and venules
Capillaries
-
A condition that occurs when the level of tissue perfusion decreases below that neee to maintain normal cellular functions; also called shock.
Hypoperfusion
-
A point where a blood vessel lies near a bone.
Pressure point
-
A bruise from an injury that causes bleeding beneath the skin without breaking the skin.
Contusion
-
1.Blood enters the righ atrium from the Vena cava
2.De-O2 blood enters the right ventical
3.The right ventricle contracts sending De-O2 blod into the pulminary artery.
4.Blood goes to lungs becomes O2inated.
5.Blood returnes to the left Atrium form the Pulmanary Veins
6.Blood enters the Left Atrium.
7.Blood enters Left Ventricule
8.Blood is then pumped into the Aorta.
Process of heart
