A client with heart disease has
been reading on the internet about the anatomy and physiology of the heart and tells the nurse: I'm so confused. The nurse reinforces the pattern of circulation in the body. Which client statement indicated a correct understanding?
A."Blood enters the heart through the ductus arteriosus, flows into the left side of the heart, and exits via the aorta into the systemic circulation."
B."Blood enters the heart from the inferior vena cava; it then flows through the left atrium into the left
ventricle, then into the lungs, and back into the aorta."
C."Blood enters the heart from the aorta, flows into the right atrium and right ventricle, through the lungs, then into the left atrium and left ventricle, and finally exits through the superior vena cava."
D."Blood enters the right atrium via the superior and inferior vena cava, flows to the right ventricle and then into the lungs, returns from the lungs to the left atrium and left ventricle, and exits out the aorta."
