Chapter 1 Cardiac anatomy and blood flow Learning goal: Trace blood through the heart and link each chamber to the signs of failure. Heart chambers and great vessels RA Receives deoxygenated blood from venae cavae.; LA Receives oxygenated blood from pulmonary veins.; RV Pumps to the lungs via the pulmonary artery.; LV Thickest wall; pumps to the body via the aorta.
SVC Returns blood from head and arms.; Aorta Largest artery; carries LV output.; Simplified teaching schematic - not to anatomical scale.; Figure 1.1 Simplified four-chamber schematic.; Path of blood flow; Venae cavae -> RA; Tricuspid -> RV; Pulmonic -> lungs; Pulmonary veins -> LA; Mitral -> LV; Aortic -> body; Figure 1.2 Right heart to lungs; left heart to body.
