Concept explainers
a.
To determine: The diagram that shows an infant with patent ductus arteriosus.
Introduction: A ductus arteriosus is a condition in developing fetus in which a blood vessel connects the main pulmonary artery to the descending aorta. It is the channel through which the majority of the blood goes into the aorta.
b.
To determine: The reason why the majority of blood bypasses the lungs of the fetus.
Introduction: The blood in the pulmonary artery of the developing fetus bypasses the lungs and enters inside the aorta with the help of ductus arteriosus.
c.
To determine: The circuit having the higher resistance if the systemic side is greater than the pulmonary side of the circulatory system.
Introduction: The fetal bypass channel closes during the first day after the childbirth but remains open in majority of the cases.
d.
To determine: The side of the heart that is required to generate a higher pressure for overcoming resistance if the flow in systemic and pulmonary circulations is equal.
Introduction: The ductus arteriosus usually closes during the first day after, but in some cases, surgery is required for closing this patent ductus arteriosus.
e.
To determine: The direction of flow of blood through patent ductus arteriosus.
Introduction: About 4,000 babies in the United States maintain an open ductus arteriosus. This patent ductus arteriosus require surgery in such patients.
