What does the abbreviation TM stand for? Tympanic Membrane
Where is the submandibular duct (Wharton duct) found? This emerges from the deep
anterior portion of the gland and drains into the anterior floor of the mouth
What scalpel blade is used in ear surgery? The #15 blade is used
What is the name of the largest vein in the body? The saphenous vein
What med is used for prevention of venous thromboembolism? Heparin
What vein is used for cardiac bypass? They use the saphenous vein
What med is used to reverse the effects of systemic heparin? Protamine sulfate
What is In Situ Saphenous Femoropopliteal Bypass? A surgical alternative to using a
synthetic graft by using the existing saphenous vein, which is anastomosed to the popliteal
artery
Tunical Externa (adventita) composed of connective tissue, it is the outside of the blood
vessel and provides structural strength
Tunica media Composed of inner layers of smooth muscle, it is the middle layer of the blood
vessel and is bounded by connective tissue
,Tunica intima This inner layer of blood vessels secretes substances that cause vasodilation
or constriction, preventing platelet aggregation in the vessel
These carry oxygenated blood from tissues back to the heart, are pressurized, and are thicker
and more elastic Arteries
These carry deoxygenated blood from tissues back to the heart, have small valves, blood moves
through them by pumping action of skeletal muscles Veins
Venous blood is ________ than arterial pressure Lower
These function as the transition and exchange mechanism for O2 and other substances
between the vessel walls and the tissue cells Capillaries

Define In Situ In the natural position or normal place, without disturbing or invading
surrounding tissue
Define Hemoptysis Blood sputum or bleeding arising from the respiratory tract
Define Diffusion (O2) The molecular passage of O2 across the alveoli and into the
bloodstream
What are Arterial Blood Gases (ABGs) A blood test that determines CO2 and O2 saturation,
pH, and other important parameters of respiration and O2 perfusion
Define Expiration the act of breathing out (exhaling)
Define Hemothorax The presence of blood in the thoracic cavity or between the pleural sac
and lungs, usually caused by trauma
Define lung volume reduction Portions of the lung severely affected by chronic pulmonary
emphysema are removed to improve pulmonary function
