1. Tricuspid Valve Located at the 4th ICS at lower left sternal border. Separates the right atrium from
the right ventricle.
2. Mitral Valve Located at the 5th ICS, left midclavicular line. Separates the left atrium from the
left ventricle.
3. Aortic Vavle Located at the 2nd ICS at right sternal border. Lies between the left ventricle and
the aorta.
4. Pulmonic Valve Located at the 2nd ICS at left sternal border. Separates the right ventricle from the
pulmonary artery.
5. Tricuspid, Pul- What is the order of the cardiac valves?
monic, Mitral,
Aortic
6. Fetal Circulation Blood flows from the right atrium into the left atrium via the foramen ovale. The
right ventricle pumps blood through the patent ductus arteriosus rather than into
the lungs.
7. 7 years of age. At what age is the adult heart position reached?
