BIO 202L – 45 Q&A | Heart Anatomy & Physiology Lab Review | ECG, Valves, Pathways

This document features 45 expertly curated Q&A pairs covering the cardiovascular system, specifically the heart, designed for students enrolled in BIO 202L – Anatomy and Physiology Lab for the 2025/2026 academic year. It is an essential study tool for learners in nursing, pre-med, health sciences, or biology programs who need to master cardiac anatomy and function for lab exams and assessments. Key topics include: Heart location and structure: apex, base, pericardial layers (fibrous, serous, visceral), myocardium, endocardium Cardiac physiology: heart rate ranges, systole vs. diastole, depolarization and repolarization Electrical conduction pathway: SA node, AV node, bundle branches, Purkinje fibers Electrocardiogram (ECG): P-wave, QRS complex, T-wave interpretation Heart valves and chambers: tricuspid, bicuspid (mitral), aortic and pulmonary valves, atria and ventricles Coronary circulation and the physiological basis for ventricular wall thickness Visual references included: labeled heart diagrams, ECG waveforms, and anatomical orientations (anterior, posterior, frontal views) Perfect for: Students in BIO 202L or related anatomy & physiology lab courses Learners preparing for lab practicals, written quizzes, or pre-clinical exams Anyone pursuing studies in cardiac physiology, nursing, EMS, or allied health programs The Q&A format promotes high-speed memorization while offering detailed, exam-relevant content that aligns with lab manuals and lecture instruction.
