explain the ligamentum arteriosum in a young animal
It is a fetal blood vessel that connects the pulmonary artery to the descending aorta.
This allows blood to bypass the non-functional fetal lungs, since oxygen is obtained from the placenta.
the ligamentum arteriosum in the fetus causes blood traveling to pulmonary trunk to bypass to the ____
aorta
what tends to happen in some animals = (one example being Yorkie) to the ligamentum arteriosum
sometimes it wont shrink= “blue baby”
what does the ligamentum arteriosum turn into once the baby begins to breath on its own
????????
subsinosal groove in the heart is below the ____
SA node
what atrium is the SA node associated with
R atrium
what is the function of the trabecula
septamarginalis
carries cardiac conduction nerve fibers from
interventricular septum to the ventricular marginal wall; markedly thicker tissue than equine spp
what view of the equine heart is this
Atrial view
**in an equine heart

List the Bovine Heart 4 major valves
*aortic valve,
*left atrioventricular valve
*right atrioventricular valve
*pulmonary valve
Between the right atria and right ventricle is what valve
Right A-V valve
Between the Left atria and left ventricle is what valve
Left A-V valve
it the left or right ventricle thicker
left ventricle (by around 1 cm more)
what is the ostium aortae
refers to the aortic opening or aortic orifice, which is the opening between the left ventricle and the ascending aorta in the heart (Dr.nadar called this a bone?)
os cordis is the bone in the heart that surrounds the aorta specific to cows (found on google??)
what is this
gemsbuck (bovidae)
