These hallmarks are intended to apply to all professional practice settings and all types of nursing practice. The hallmarks may be useful to new graduates, practicing nurses, students, faculty, nurse executives and managers, and employers across all nursing practice settings.
The right ventricle receives blood from the right atrium across the tricuspid valve, which is located in the large anterolateral (ie, sinus) portion of the right ventricle. The right ventricle discharges blood into the pulmonary artery across the pulmonic (semilunar) valve located in the outflow tract (infundibulum). The inflow tract (sinus) and outflow tract (infundibulum) of the right ventricle are widely separated.
The systemic loop begins when the oxygen-rich blood coming from the lungs enters the upper left chamber of the heart, the left atrium. As the chamber fills, it presses open the mitral valve and the blood flows down into the left ventricle.
