Ünite 1: Cardiovascular System — Sınav Hazırlık Notları

• Pay close attention to valve locations and names; remember that the bicuspid valve is also known as the mitral valve and is located on the left side of the heart.
• Do not confuse systemic and pulmonary circulation pathways regarding oxygenation status; remember that pulmonary veins carry oxygenated blood unlike all other veins.
• Memorize the exact components of the heart's intrinsic conduction system in sequence: SA node, AV node, Bundle of His, bundle branches, and Purkinje fibers.
• Note the anatomical differences in myocardial thickness; the left ventricle is significantly thicker than the right because it pumps against higher systemic resistance.
• Keep track of the aortic arch branches (brachiocephalic trunk, left common carotid, left subclavian) as exam questions frequently test their exact origins.
• Remember that the descending aorta bifurcates at lumbar vertebra L4 into the common iliac arteries, a specific anatomical landmark often featured in tests.
