Oxygenation and exchange of carbon dioxide a fetal blood takes place in the maternal ________. |
Placenta |
|
|
Oxygenated blood returns to the fetal heart via the umbilical _______. |
Vein |
|
|
The _________ __________ delivers blood from the umbilical vein to the inferior vena cava, thus bypassing the liver. |
Ductus venosus |
|
|
The ______ valve directs blood entering the RA .to the foramen ovale |
Eustachian |
|
|
True or false: in the fetal heart, the shunt between the Atria is right to left. |
T |
|
|
Deoxygenated blood returns to the placenta via the umbilical ________ in fetal circulation. |
Artery |
|
|
True or false: with birth, the lungs inflate, right atrial, right ventricular and pulmonary artery pressures decrease and left heart pressures increase. |
T |
|
|
The ________ ________ closes upon birth due to an increase in oxygen content in the aorta. |
Ductus arteriosu |
|
|
The ductus arteriosus becomes the ________ _________ in the adult. |
Ligamentum arteriosum |
|
|
The _________ ____________ closes due to a decrease in blood flow across the bustle, thus allowing blood flow to the liver. |
Ductus venosus |
|
|
The ductus venosus becomes the __________ _________ in the adult. |
Ligamentum venosum |
|
|
True or false: blood enters the systemic arterial fetal system from two sources: the ductus arteriosus of the ascending aorta. |
T |
|
|
during fetal circulation the RV pumps against a highly resistant pulmonary bed and arterial bed which means the fetal RV will be thicker?/thinner? than the LV. |
Thicker |
|
|
True or false: during fetal circulation the right heart handles a larger volume of blood than the left heart? |
T |
|
|
True or false: during fetal circulation the left and right pulmonary arteries are relatively under developed at birth due to the decrease in the flow volume of blood? |
T |
