IS the right atrium where the process really begins?

The question is what process, then I can say whether that is where the process begins.

The liver lies on the right side of the abdominal cavity beneath the diaphragm

I'm not sure if this is enough info but...\nWhen the Left Atrium is full of blood, the heart muscle in the Left Ventricle relaxes so the muscles attached to the Mitral Valve open.

Ill try-\nBlood comes into the right atrium, then to the right ventricle..it stays on the right side at first.  This blood doesnt have any oxygen in it, so the first thing you have to do is get it oxygenated-So, the blood goes from the right ventricle to the lungs.  Here, the blood picks up oxygen for the rest of the body, but it still has to be pumped to the rest of the body.  So the blood goes fro mthe lungs back to the heart, but this time it goes into the left atrium, then the left ventricle-from there is goes everwhere in the body, delivering oxygen.  Now, once the body has taken all the oxygen out, the blood goes back to the right atrium, for the whole cycle to start again.\nhere's the overall flow:\n\nBlood from the body without oxygen--->\nright Atrium--->Right Ventricle--->\nLungs, so it can get oxygen--->\nLeft Atrium--->Left Ventricle--->\nRest of the body, to deliver oxygen---->\nBack to the right atrium once the oxygen is used.

Precordial activity refers to the movement of the chest wall when the heart beats.  When the heart beats it pushes against the rib cage and diaphragm in a certain way.  An experienced health care provider can often tell by palpating (touching) for the apex (pointed end) of the heart, whether there is enlargement, disease, damage, and to what extent.  Terms such as lifts, heaves, and thrills are used when notating location and duration of the movement.  An easy to understand example might be that the apex of the heart can be felt lower or more to the right in a patient with an enlarged heart, than one with a normal heart.  Precordial activity by itself isn't a term that means there is anything wrong.  All hearts have precordial activity.

Wow, i just had this done today. I was at my Dr.'s office last week and i told him it hurts real bad to turn my neck to the right but i can turn it to the left. He listened to my neck with a stethoscope and then ordered a carotid Doppler done on both side of my neck. I guess the lady in the office said my Dr. heard something. He will be calling me in a few days with results. Go to your Dr. now and ask for the Doppler test to be done on both side. Takes about 30 Min's ... maybe 45 min.'s tops and all you have to do is lay there.\ngood luck.

Well that depends on the cause of the heart murmurs.  An ultrasound of the heart is usually the next step.  Murmurs can be completely normal in some people.  It could also indicate a leaky or misfunctioning heart valve, a small hole between chambers of the heart, or a dilated aorta or pulmonary artery.  If a cause is found, then you can find out what treatments are available.  But the cause needs to be identified first.  Chest X-rays and EKG's are often ordered, but an ultrasound (or echocardiogram) will be the test that definitively tells you the cause.

Usually the mitral valve.

Coronary arteries (left and right). They branch from the ascending aorta just after its start. These arteries fill with blood during diastole.\nFor more detailed information on their anatomy see:\nhttp://mywebpages.comcast.net/wnor/thoraxlesson4.htm\nhttp://www.clevelandclinic.org/heartcenter/pub/guide/disease/cad/cad_arteries.htm\nhttp://en.wikipedia.org/wiki/Coronary_artery\nhttp://www.hsforum.com/stories/storyReader$1480

Your appendix is on the right, so it isn't appendicitis.  (There is no way that the appendix can be on the left in case you were wondering)  The spleen is on the left, but it is located right under the ribcage.  Your kidneys are low in your abdomen and are located on both sides.  I would guess that it has something to do with your intestines though.

The first ultrasound visit is typically scheduled between 8-10 weeks to confirm the heart beat.

It is indeed the tricuspid valve. It is one of the Atrioventricular valves named so because of the location between the Atria of the heart and the ventricles. The tricuspid valve is the valve between the right atria and the right ventricle. Its job is to prevent blood flow from the right ventricle back into the right atrium, when the right ventricle is contracting. In your case there is some blood making its way backwards into the right atrium, this is not normal. It means that your valve has some degree of incompetence, Likely you have a murmur. If it is not large your doctor may just decide to leave it alone, if it gets worse or it is large now then the only fix is to have a valve replacement. The good news is that the current valve technology is excellent.

There are several places one would be able to detect it: the corotid artery on the outside of the neck, the artery in the groin, the wrist, the temples of the head, and you could listen for a beat above the chest cavity. The place in which it should be easiest to feel is the groin.

my only guess would be an upper right quadrant ultrasound.  That is where you liver is located.  The reason looks like abnormal liver functions test.

There is no mixing of oxygen rich blood and oxygen poor blood because the chambers keep the blood from mixing.  The four chambers are the right atrium, the left atrium, the right ventricle, and the left vetricle (here's a diagram, it should help you visualize my expalantion: http://en.wikipedia.org/wiki/Image:Heart_labelled_large.png_\n\nThe process starts when the right ventricle pumps oxygen poor blood to the lungs, where it picks up oxygen.  The blood then goes back to the left atrium.  The blood in the left atrium is transfered to the left ventricle by way of a one-eay valve in the heart.\n\nThe blood in the left ventricle is pumped throughout the rest of the body. (head, arms, legs), where it drops off its oxygen, and the oxygen poor blood returns to the right atrium.  This oxygen poor blood is then transfered to the right ventricle by way of a one-way valve, where the process begins again.\n\nAs you can see, there is no mixing of the oxygen richa and poor blood because the valves in the heart (and in the arteries and veins!!) keep the blood from moving backward in the cycle.  This is important because if the oxygen rich and poor blood mixed, there wouldn't be as much oxygen getting to the body cells, which is inefficient.  Some cells might not get any oxygen and could die if the blood mixed.
