Cardiovascular system
-
-
Types of Blood Vessels, Structure, and Function
Arteries: thick muscular walls, carry blood away from heart.
-
Capillaries: thin walls for exchange of gases, nutrients, wastes.
-
Veins: thin walls, valves to prevent backflow, carry blood to heart
-
-
Basics of ECG, Leads, and Waves
-
Limb leads (I, II, III) and augmented leads (aVR, aVL, aVF) view frontal plane.
-
Waves: P (atrial depolarization), QRS (ventricular depolarization), T (ventricular repolarization)
-
-
-
-
Vasculature of the Heart
Coronary arteries: left coronary (LAD and circumflex branches), right coronary (marginal and posterior interventricular branches).
-
Great cardiac, middle cardiac, small cardiac, and anterior cardiac veins.
-
Diffusion in Capillaries
-
Thin walls allow oxygen, CO₂, nutrients, and wastes exchange.
