Answer:

A patent ductus arteriosus permits <u>blood to flow from the aorta into the pulmonary trunk </u>

Explanation:

Ductus arteriosus is an important part of foetal ciculation and acts as a shunt between pulmonary trunk and aorta allowing the deoxygenated blood to bypass the lungs and aorta. It normal fuses at birth ( 72 hours after birth)

If the ductus arteriosus fails to collapse at birth, a patent vascular channels forms connecting the pulmonary trunk an aorta shunting the blood from left to right allowing the oxygenated blood to pass back through the blood vessels in lungs.

What are two ways to tell if bleeding is life-threatening?

Afina-wow [57]

The two ways to tell if bleeding is life-threatening are to check if it is spurting or pulsating blood or steady slow flow blood and whether it is bright red color or dark red color blood.

The purting or pulsating blood is usually bright red in color. It can be life-threatening. The steady slow flow blood is usually dark red in color. It can be potentially life-threatening.

In cases of severe bleeding, direct pressure should be applied immediately to the wound with any clean material which is available at the time. Pressure should be continued until the bleeding is controlled. The wound above the affected person's heart should be elevated. The person should be lying down with the legs elevated.
