Are there external and internal carotid arteries on both the left and right side of the neck?

yes, there are a internal and external on the both side of the neck and it's just one Willi's circle , but this connects with the both in front of the "protuberance".

Have the carotid endarterectomy done.  Without a doubt!!  This is a very common procedure, these docs do it all the time.  It sounds scary but all it really is, is the plaque buildup being scraped out of the carotid artery.  The carotid is the main artery to your brain.  If there is a blockage your brain is not getting enough oxygen and bloodflow.  Definately go ahead with the procedure, the benefits well out weigh the risks!!

Head & neck? Do you perhaps mean brain and throat?

I would have to say the right-lower side of my neck and my inner-upper thigh.

The three major fascial layers in the neck contribute to the carotid sheath: the investing fascia, the pretracheal fascia, and the prevertebral fascia.

Because the liver occupies space above the right. And, the blood supply for the right kiney branches off the aorta lower.

Well, the cervical may be problematic... There are anterior and posterior.  In the anterior triangle of the neck, bounded by the sternal heard of the sternocleidomastoid laterally, midline medially, and clavicle inferiorly, you have the trachea, thyroid, larynx, common carotid artery, external carotid artery, internal jugular vein, anterior jugular vein, and hypoglossal nerve (cranial nerve XII) as major structures.  There are also lymph nodes and several smaller muscles.  \nThe posterior triangle is bounded by the posterior side of the sternocleidomastoid, the anterior side of the trapezius, and inferiorly by the clavicle.  It contains many nerve roots, the medial end of the brachial plexus, the third part of the subclavian artery, the suprascapular artery, the occipital artery, the external jugular vein, and occasionally the subclavian vein.\nThe femoral triangle is bounded by the inguinal ligament superiorly, the sartorius laterally, and the medial border of the adductor longus medially.  It contains the terminus of the femoral nerve, the branches of the femoral nerve, and the femoral artery and vein, along with a string of lymph nodes.

The spleen and the stomach are under the rib cage on the left side....pancreas is more midline....liver and gallbladder are right sided.\n\nSpleen:  Upper left quadrant, left hypochondriac region, articulated with ribs 9-11 (laterally). \nhttp://www.geocities.com/doctor_uae/abdomen.htm\n\nPS:  the link supplied by the person above me is a good one, but you have to realize this.  You have to look at that drawing like you are looking at an actual person.  So, the liver is on the person's right side, not on the viewer's right side....

There are two possible answers.  Are you referring to the oxygenated blood pathway and the deoxygenated blood pathway or the arterial and venous pathways?  In either case, here is a quick rundown. \n\nThe pathway of oxygenated blood:\nStarting in the lungs:  Pulmonary capillaries, pulmonary venuoles, pulmonary veins, to the left atrium through the mitral valve to the left ventricle, through the aortic valve to the aorta, the arteries, the arterioles and to the systemic capillaries throughout the body.\n\nThe pathway of deoxygenated blood:\nStarting in the systemic capillaries, the venules, veins, then into the right atrium from either the superior vena cava, inferior vena cava or the coronary sinus, then through the tricupid valve into the right ventricle, through the pulmonary valve, the pulmonary arteries, pulmonary arterioles, and into the pulmonary capillaries of the lungs. \n\nArtery Pathway:  Pulmonary Arteries, Coronary Arteries, Aorta, Common Cartoid Artery, Subclavian Artery, Auxillary Artery, Brachial Artery, Radial Artery, Ulnar Artery, Brachiocephalic Artery, Common Iliac Artery, Internal Iliac Artery, External Iliac Artery, Femoral Artery, Popliteal Artery, Anterior Tibial Artery, and Posterior Tibial Artery\n\nVenous Pathway:  Pulmonary Veins, Cardiac Veins, IVC, SVC, Internal Jugular Vein, Subclavian Vein, Auxillary Vein, Brachial Vein, Radial Vein, Ulnar Vein, Brachiocephalic Vein, Common Iliac Vein, Internal Iliac Vein, External Iliac Vein, Femoral Vein, Popliteal Vein, Anterior Tibial Vein, and Posterior Tibial Vein

The right side of the heart is for pulmonary circulation. this is to take blood from the tissues rich in co2 and lower in Oxygen and circulate it thru the lungs. In the lungs the co2 is dumped off and a fresh load of oxygen is picked up by the hemoglobin in the red blood cell. The left side of the heart now gets this fresh blood and the left ventricle pumps blood thru the body but not the lungs. the right ventricle pumps blood thru the lungs.

The most sensitive part is right along the carotid artery and jawbone. Kiss it, lightly bite it.

Baroreceptors allow the body to sense blood pressure and thus help regulate it.  Arterial baroreceptors are located in the carotid sinus,( where the internal and external carotids branch) and in the aortic arch.  Low pressure baroreceptors are found in large veins and the walls of the atria.

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.
