The Umbilical arteries:
a. carry blood towards the foetal heart
c. derive from the foetal aorta
c. derive from the foetal internal iliac arteries 
d. carry highly deoxygenated blood

Blood from the umbilical vein first carries blood into the:
a. Foramen ovale
b. Ductus venosus 
c. Ductus arteriosus
d. Inferior vena cava 

From the foetal inferior vena cava blood drains into the:
a. Left atrium 
b. Right atrium
c. Ductus venosus 
d. Ductus arteriosus

In foetal life the foramen ovale allows the passage of blood from:
a. The left ventricle into the right ventricle
b. The right ventricle into the left ventricle
c. The left atrium into the right atrium
d. The right atrium into the left atrium 

In late foetal life how many pulmonary veins drain into the left atrium?
a. 1
b. 2
c. 3
d. 4 

In late foetal life the ductus arteriosus shunts blood from the: 
a. Umbilical vein into the inferior vena cava
d. Right atrium into the left atrium
c. Pulmonary artery into the aorta 
d. Aorta into the pulmonary artery

Increased pulmonary oxygenation immediately after birth will:
a. Decrease pressure in the right atrium
b. Vasoconstrict pulmonary arterioles
c. Vasodilate pulmonary arterioles 
d. Vasoconstrict systemic arterioles

Bradykinins released at the time of birth will:
a. Dilate the umbilical vein
b. Dilate the ductus venosus
c. Constrict the pulmonary arterial system
d. Aid in the constriction of the ductus arteriosus
