what is the difference between the right and left caritoid arteries?
83107
Carotids supply the heart? I think the previous poster is confused.\n\nThe only main difference is that the left common carotid branches off directly from the aorta, whilst the right common carotid branches off the brachiocephalic artery. other than that, they both ascend and divide eventually into internal and external carotid arteries on each side.

There are three major coronary arteries. Two on the left (with a common trunk) and one on the right. They branch off from the aorta near the point where the aorta and left ventricle meet.

The circulatory system comprises all structures that relate to the circulation of blood throughout the body.  This includes the heart, the aorta (main artery coming out of the heart), the major organ arteries, the smaller branch arteries going into the organs, arterioles (even smaller branch arteries), capillaries (fine, almost microscopic vessels where oxygen and nutrients are delivered to the organ), venules (small veins that start the return of blood away from the organ), small veins, larger veins, inferior vean cava (main vein from the lower 2/3 of the body), superior vena cava (main vein from the upper 1/3 of the body), and finally the heart again.  The circulatory system is essentially a closed plumbing system, driven by the beating of the heart.

Basilic vein -> axillary vein -> subclavian vein-> right inominate -> superior vena cava -> right atrium -> right ventricle -> pulmonary arteries -> lungs -> pulmonary veins -> left atrium -> left ventricle -> aorta -> commo iliac artery -> external iliac artery -> femoral artery -> anterior tibial artery -> dorsalis pedis -> toe

After the blood leave the left ventricles it passes through the aorta and the aorta take the blood to the whole body

The heart is located in the thoracic cavity between the lungs. If you were to draw a vertical line down the center of the chest, you would find that about two-thirds of the heart is on the left and one third on the right. The pointed end of the heart points to the left. So we can say that the heart is mostly on the left side.

The heart muscle, like every other organ or tissue in your body, needs oxygen-rich blood to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation. \n\nThe aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.\n\nThe right coronary artery supplies blood mainly to the right side of the heart. The right side of the heart is smaller because it pumps blood only to the lungs.\n\nThe left coronary artery, which branches into the left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart. The left side of the heart is larger and more muscular because it pumps blood to the rest of the body.

As you might already know that the heart has 2 ventricles- the right ventricle and the left ventricle.\n\nRight ventricle:\nReceives deoxygenated blood (without O2) from right atrium (from the body via Superior & Inferior Vena Cava), and pumps it into the lungs, where the blood may remove CO2 and retrieve O2 from the lungs- which isn't very far off.\n\nLeft ventricle:\nReceives oxygenated blood (with O2) from left atrium (from lungs) and pumps it into the system, i.e. the body. \n\nIn order to reach all parts of body (extremities included), the left ventricle has to work extra hard to maintain pressure and achieve this. That means, it also needs the capacity to handle such extra pressures, therefore, the left ventricle wall is thicker than the right one.\n\nThe ratio of right ventricle to left ventricle is 1:3, meaning, the left ventricle walls are 3 times thicker than the wall of right ventricle.

At first the "lefty" had two sides and looked like the down-hill forks in construction. The steerer tube was in the middle and each leg extended past that on the left and right. It was of course heavier compared to the traditional styled forks (fork legs are more or less even with the steere tube). The guys in charge of the Cannondale fork were told to lighten it up so they cut off one side. This style was also used on some motorcycles I believe. Anyway, the advantage of the "lefty" is that you can get more travel out of it that the tradition forks at roughly the same weight. Also, the internals are interchangeable so you can upgrade the low end model to use the same internals as the high end model. The down side is that to remove the front wheel, you have to remove the disc brake caliper. You also need an adpater to true up the front wheel. There is also an adapter needed to transport the bike on roof racks where the front wheel is removed.

Heart, arteries, veins.

Arteries are muscular blood vessels that carry blood away from the heart. They are contrasted with veins, which carry blood toward the heart.\n\nThe circulatory system is extremely important in sustaining life. Its proper functioning is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, maintenance of optimum pH, and the mobility of the elements, proteins and cells of the immune system. In developed countries, the two leading causes of death, myocardial infarction and stroke each may directly result from an arterial system that has been slowly and progressively compromised by years of deterioration.

An Aorta is a large Artery coming straight off your heart. It is where most your vessels begin to take to the rest of your body. He might have been born with a reduced size (a typical aorta is very large size of 2 fingers) so it takes longer for the body to pump the blood to areas of the body. It is most likely a genetic thing or a fluke that happened during development. I do not know about being born completely with out an aorta.

It's usually on the lower right side of your abdomen, but some people have it on their left side (those with "situs inversus" which means their organs are on opposite sides from normal).
