Identify and label various structures and arteries related to the cardiovascular system, including the tunica layers of blood vessels, valves, vasa vasorum, arteries, veins, major arteries of the abdomen and limbs, and specific labeled arteries such as the aorta, subclavian, carotid, femoral, and others. Additionally, label structures of the heart including the apex, ascending aorta, aortic arch, and coronary structures, as well as veins like the superior vena cava and pulmonary veins. Emphasize proper labeling of each anatomical structure with Left/Right designations where appropriate, and include the labeled arteries of the abdomen and limbs.
Furthermore, familiarize yourself with the National Patient Safety Goals (NPSGs) including timely communication of test results, patient identification, infection prevention, surgical correctness, medication safety, alarm management, and patient safety risk identification. Learn to properly label medical diagrams such as heart structures and blood vessels, including the aorta, ventricles, atria, and associated sulci. Recognize and label key lymphatic structures including lymph nodes and lymphatic ducts. Identify the components of hematocrit, blood cell types, and their normal ranges, as well as the classification of blood types according to surface antigens and compatible donors. Finally, determine heart rate and intervals from EKGs, and understand the basic sounds of the heartbeat, with attention to safety and accuracy in patient care and data interpretation.

The cardiovascular system is a complex network of vessels, structures, and tissues that work synergistically to sustain life by circulating blood, transporting nutrients, gases, and waste products. An essential aspect of understanding this system involves accurate identification and labeling of its components, including the blood vessel layers—namely, the tunica interna (intima), tunica media, and tunica externa (adventitia)—and associated structures such as valves, vasa vasorum, arteries, and veins. Properly distinguishing arteries from veins, especially in their route from the heart to various parts of the body, provides crucial insight into circulatory physiology and pathology.
Key arteries of the abdomen, such as the celiac trunk, superior and inferior mesenteric arteries, and their branches including the common hepatic, splenic, gonadal, and internal/external iliac arteries, are vital in supplying blood to abdominal organs. On the limbs, arteries like the femoral, popliteal, tibial, and fibular arteries are significant for their roles in perfusion. Each of these vessels must be identified with the correct left or right designation to understand anatomical layout and clinical implications. The structural features, such as the internal and external carotids and subclavian arteries, are equally important for understanding cerebrovascular and upper limb blood supply.
In cardiology, the identification of heart structures including the aorta, pulmonary trunk, ventricles, atria, coronary sulcus, and interventricular sulci helps elucidate cardiac function and blood flow dynamics. Labeled diagrams of these structures assist in comprehending the vessel pathways and the flow of oxygenated and deoxygenated blood. The lymphatic system's components—such as axillary, inguinal, cervical lymph nodes, and thoracic and cisterna chyli ducts—are integral to immune function, and understanding their location enhances the grasp of lymphatic circulation.
Understanding blood components involves knowledge of hematocrit, which comprises plasma, erythrocytes, and formed elements like platelets and leukocytes. The normal ranges for hematocrit differ between men and women, reflecting physiological variations. Blood type classification hinges on the presence or absence of surface antigens (A, B, Rh), with compatible transfusion options based on these antigen-antibody interactions. Blood types such as O-, A-, B-, and others determine safe donation and transfusion strategies, which are critical in clinical practice.
Electrocardiogram (EKG) analysis allows for assessment of cardiac electrical activity, with the identification of key waves—P, QRS complex, and T wave—that reflect atrial and ventricular depolarization and repolarization. Calculating intervals such as the PR and QT intervals provides insight into conduction pathways and potential arrhythmias. Recognizing heartbeat sounds—“lubb” and “dupp”—corresponds to specific valve closures (atrioventricular and semilunar valves, respectively), facilitating the diagnosis of cardiac function and rhythm abnormalities. Accurate HR calculations and interpretation of these parameters are fundamental skills for health professionals.
