Chapter 20, Problem 27RQ
The ductus venosus is a shunt that allows ________.
- fetal blood to flow from the tight atrium to the left atrium
- fetal blood to flow from the light ventricle to the left ventricle
- most freshly oxygenated blood to flow into the fetal heart
- most oxygen-depleted fetal blood to flow directly into the fetal pulmonary trunk

In all humans the first three arteries to branch off of the aortic arch are brachiocephalic trunk, left common carotid artery and left subclavian artery.
True
False
Fossa ovalis exists in a fetal heart and turns into foramen ovale upon birth.
True
False
Atrial muscles contract from the base down, while ventricular muscles contract from the apex upwards.
True
False
Capillary hydrostatic pressure is higher than the capillary osmotic pressure at the beginning of the capillary, but is lower at the end of the capillary.
True
False
The mitral valve is located between the
Locate the following blood vessels (in bold) in the fetal pigl
Arteries:
aorta (arch)---dorsal to the pulmonary trunk
anterior vena cava and posterior vena cava.
brachiocephalic artery--- the first branch off the aorta
The brachiocephalic artery branches into three other arteries: the right subclavian (passes under the clavicle), and the right and left carotid arteries
The right subclavian continues and becomes the right axillary then right brachial artery.
The left subclavian artery is dorsal to the brachiocephalic off of the aortic arch
Follow the aorta dorsally where it becomes the dorsal or descending aorta , then the abdominal aorta
The renal artery that connects the kidney to the medial abdominal aorta
At about the level of the renal artery, you may see the very tiny (diameter) gonadal arteries.
The abdominal aorta terminates in four branches: the right and left external iliac, and the right and left internal iliac arteries.
