Question

The mother of a three-month-old infant was concerned because her child had little energy and did
not seem to be thriving. You examine the child and suspect the presence of a congenital cardiac
defect, most likely a patent ductus arteriosus. What other symptoms would accompany this
diagnosis?
Left-to-right shunting of blood between the atria
Notching of the ribs created by dilated intercostal arteries
Decreased oxygen in the systemic circulation
Distension of the right atrium
Increased blood flow in the pulmonary circulation

Expert Solution

Step 1

The cardiovascular system is a crucial component of the circulatory system in humans (which is often known as the circulatory system). The cardiovascular system is composed of:

1. The heart (Major pumping organ and the epicenter of the CV system)

2. Blood (Primary circulatory fluid of the body)

3. Blood vessels (The tubular segments that help in the conduction of blood to and from the heart to various regions of the body)

The heart is the most primitive structure to form and develop in the human embryo and the anomalies associated with the development of the heart and associated structures can hamper the cardiovascular interactions of the body which can be life-threatening.
