Cheat Sheet
- Heart anatomy and blood flow -
Review the four chambers (RA → RV → lungs → LA → LV) in sequence for pulmonary and systemic circuits. This circuit is a staple on circulatory system quizzes, so use the mnemonic "RA RV LA LV" to keep your order tight. The American Heart Association details this pathway in its anatomy guides.
- Cardiac conduction system -
Understand the pathway: SA node → AV node → Bundle of His → Purkinje fibers, which coordinates atrial and ventricular contraction. Remember "Some Atria Always Validate Heartbeats" as a mnemonic for SA, AV, His, Purkinje. University cardiology guidelines highlight this for ECG interpretation.
- Vessel types and flow resistance -
Differentiate arteries, veins, and capillaries by wall thickness and function; arteries handle high pressure while capillaries facilitate exchange. Apply Poiseuille's law (Flow = ΔP·πr❴ / 8ηl) to see how small radius changes massively affect flow, per NIH physics research.
- Blood pressure and mean arterial pressure -
Memorize systolic vs. diastolic pressures (e.g., 120/80 mmHg in a healthy adult) and calculate MAP ≈ diastolic + ⅓(systolic - diastolic) to assess tissue perfusion. This formula is standard in American College of Cardiology reviews and ACLS protocols confirm its clinical relevance.
- Oxygen transport and the Bohr effect -
The oxyhemoglobin dissociation curve shifts right with increased CO₂, acidity, temperature, and 2,3-DPG (mnemonic "CADET, face Right"). This facilitates O₂ unloading in tissues, as detailed by Guyton and Hall's physiology texts. Study curve graphs to predict oxygen delivery under varying conditions.
