BodyLab

Heart Explorer — Cardiovascular MVP

Interactive heart anatomy with a 3D-ready viewer shell, layer toggles, label quiz, physiology pathway, myocardial infarction overlay, nursing relevance, and NCLEX review.

Educational tool only — AI-assisted anatomy content for study and NCLEX-style practice. Not a substitute for professional medical training, evaluation, or advice.

Nursing relevance

Left Ventricle

Why it matters

Left ventricular function determines cardiac output; monitor blood pressure, lung sounds, and signs of pulmonary edema.

Key assessments

Auscultate heart sounds systematically, noting S1/S2 intensity, murmurs, and extra heart sounds.
Assess peripheral perfusion, pulse quality, capillary refill, and signs of congestion.
Monitor respiratory status for crackles and orthopnea in left-sided heart dysfunction.

Common labs

Troponin I/T — <0.04 ng/mL
BNP — <100 pg/mL
Serum potassium — 3.5–5.0 mEq/L

Interventions

Administer oxygen and aspirin per acute coronary syndrome protocol.
Position the patient upright, monitor telemetry, and prepare for 12-lead ECG.
Educate the patient about chest pain reporting, activity pacing, and medication adherence.

Accuracy checklist

Chambers are separated into right and left atria and ventricles.
All four cardiac valves are represented and labeled.
Coronary vessels include the RCA and LAD with a clinically relevant overlay.
Conduction nodes include both SA and AV nodes.
Blood flow step sequence matches right heart → lungs → left heart → aorta.
Pathology overlay clearly shows anterior wall myocardial infarction.
Nursing relevance panel connects structure, assessment, labs, interventions, and conditions.
NCLEX mini-quiz uses clinical-style questions with rationales.
Source references are included and tied to nursing/clinical content.
