Ch 7 Flashcards
Aorta
Largest artery in the body
Anticoagulant
Prevent blood clotting
Arteries
Highly oxygenated blood vessels. Carry blood away from heart.
Arterioles
Smaller branches if arteries
Atria
Two of the four chambers if the heart.
Right side- oxygen poor
Left side- oxygen rich
Basilic vein
Vein running down pinky side of the arm.
3rd choice for ventipuncture. More nerves.
Capillaries
Link arterioles to venues
Cephalic vein
Thumb side of arm.
2nd choice for ventipuncture
Differential
Lab test that enumerates and categorizes WBC and any abnormalities
Edema
Swelling
Fibrin
Substance that forms a blood clot
Fibrinolysis
Final phase of hemostatic process where repair and regeneration of injured blood vessel occurs. Clot slowly begins to dissolve.
Hematocrit
Lab test to assess circulatory system. Indirect measures to oxygen carrying capacity if blood
Hematopoietic
Blood forming
Hemostasis
Maintenance of circulating blood in liquid state and retention of blood by prevention of blood loss
Inferior vena cava
Bring oxygen poor blood to heart from lower trunk and legs
Intrinsic
Coagulation process that involves clotting factors
Median cubital vein
Vein in ante cubital area ( bend of arm). Most common for ventipuncture
Thrombocytes
Platelets.
Component of blood that aids in clotting.
Lifespan in 9-12 days.
Low count- thrombocytopenia
Erythrocytes
RBC
Transport oxygen and carbon dioxide in blood
Serum
Similar to plasma. Without clotting elements that are in plasma
Systemic circuit
Part of cardiovascular system that carries oxygenated blood to tissues
Vasoconstriction
Rapid constriction of blood vessels to decrease blood flow to area
Veins
Blood vessels that carry blood toward the heart after oxygen had been delivered to the tissues.
Carry deoxygenated blood
