The
largest artery
in the body is the aorta which carries oxygenated blood away from the left ventricle of the heart out to the rest of the body. Branching off of the anterior aorta, the carotid arteries supply blood to the right and left side of the head and neck.
What cavity is the aorta in?
The aorta remains at the dorsal midline of
the thoracic and abdominal cavities
. The aorta carries oxygenated blood under high pressure as it leaves the left ventricle of the heart.
Where is the aorta located in a fetal pig?
The aorta is found
behind the pulmonary trunk
. The first part of the aorta, where it leaves the left ventricle is known as the ascending aorta. The curved part is known as the aortic arch.
What is the function of the aorta in a fetal pig?
function:
to carry oxygenated blood from the aorta to small arteries in the chest and abdomen
. has two sections: the abdominal aorta and the thoracic aorta.
How many branches come off the aorta in the pig?
The pig has
two branch
arteries from the aortic arch, the BCT and the LSA (Fig 3).
How long does a pig valve last in a human?
Tissue valves, which are made from pig heart valves or cow heart-sac tissue, typically last
about 15 years
. But they usually don’t require the lifelong use of anti-clotting drugs. Older people are more vulnerable to the bleeding side effects of warfarin.
How much does a pig heart valve cost?
And, you definitely can’t purchase a Medtronic Freestyle pig valve from Amazon.com. However, I can share some anecdotal pricing information that I’ve collected over the years: A cardiac sales representative told me, “Most mechanical and tissue valves go for
about $5,000
.”
What parts of the body does the aorta supply blood to?
In the abdominal cavity the aorta gives off a number of branches, which form an extensive network supplying blood to the
stomach, liver, pancreas, spleen, small and large intestines, kidneys, reproductive glands
, and other organs.
How many branches does the aorta have?
There are
three
major branches arising from the aortic arch. Proximal to distal: Brachiocephalic trunk: The first and largest branch that ascends laterally to split into the right common carotid and right subclavian arteries. These arteries supply the right side of the head and neck, and the right upper limb.
What organs does the aorta supply blood to?
The
heart
itself gets oxygen from arteries that come off the ascending aorta. The head (including the brain), neck and arms get oxygen from arteries that come off the aortic arch. The stomach, intestines, kidneys and other vital organs get oxygen from arteries that come off the abdominal aorta.
How can you tell if a fetal pig is male or female without cutting it open?
Determine the sex of your pig by looking for the urogenital opening. On females, this opening is located near the anus. On
males, the opening is located near the umbilical cord
. If your pig is female, you should also note that urogenital papilla is present near the genital opening.
What organ is the esophagus attached to in a fetal pig?
The esophagus is dorsal to
the trachea
. The large hard structure attached to the trachea is the larynx. It contains the vocal chords.
Do fetal pigs have teeth?
The fetal pig develops primary teeth
(which are later replaced with permanent teeth). Some may erupt during fetal stage, which is why some of the fetuses show evidence of teeth.
What color is the aorta in a pig?
The curved part is known as the aortic arch. The rest of the aorta is known as the descending aorta. They look
white
because of their thick walls. If you have injected animals, they will have colored latex on the inside, but it is not visible externally.
How does fetal pig blood circulation differ from blood circulation in a fully developed pig?
Fetal circulation is different from adult circulation. In the fetus,
blood doesn’t get oxygenated in the lungs
; it gets oxygenated at the placenta. … The blood entering the right atrium is the most oxygenated blood in the fetal heart, but it’s the least oxygenated blood in the adult heart.
What is the largest vein in a fetal pig and why?
Inferior Vena Cava
. The largest vein in the body is the vena cava which brings deoxygenated blood from the body back to the heart and lungs to be reoxygenated.
