space at the sternal border due to increased blood flow through the vessels?
a) Diastolic murmur Incorrect

increased blood flow through normal vessels. The mammary souffle is commonly heard
during late pregnancy or lactation. It is heard loudest in the second or third intercostal
space at the sternal border, and is typically both systolic and diastolic, though only the
systolic component may be audible.
