Biol 3401 1st Edition Lecture 10Current LectureCardiovascular CircuitPulmonary Circuit- Right side of the heart o R. atrium and ventricle o Pumps partially deoxygenated blood to the lungs  Picks up oxygen and off CO2o Low pressure  Only pumps to the heart  Thin myocardium Systemic Circuit - Left side of the heart o L. atrium and ventricle o Pumps oxygenated blood to entire body, head, and heart (coronary circulation) Supplies tissue with O o High pressure system  Pumps blood to extremities, back to the heart - Partial failure of the L heart is more critical than R.o L. can compensate in short term Tissue of the Heart - Pericardial layers o Parietal pericardium  Anchors to the diaphragm and major vesselso Visceral pericardium These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. Associated with the myocardium - Pericardial cavity o Fluid lubricates heart o Pericarditis- Valves o Fibrous, endothelial lined cuspso Prevent back flow o Passively open and close based on pressure  Ventricular pressure  Tricuspid and bicuspid  Lub-dub sounds- Blood flow pattern1.
