i think it's your aorta.
no... it's 11 letter's long... it can't be that.
The aorta is the main artery leaving the heart into the systemic circulation. The aorta branches into progressively smaller arteries.
Stop cheating
The aorta.It originates from the left ventricle of the heart and extends down to the abdomen, where it branches off into two smaller arteries (the common iliacs).
Right and left coronary arteries.
You have pulmonary aorta that arises from the right ventricle. It splits into right and left branches. The branches most probably continue to divide with the bronchi. Ultimately you have the network of the capillaries to cover the alveoli.
Two coronary arteries branch off of the ascending aorta immediately upon exiting the heart. These two arteries (and their branches) are what nourish the cardiac muscle itself.
The left and right coronary arteries.
The aorta. This is the primary artery in your body that branches off into the many small arteries that supply nutrients to your whole body.
Mainly arteries and veins. The smaller pathways are veinules, capillaries, etc. Arteries carry blood away from the heart and to the organs. Veins carry blood back to the heart from the organs, after the blood has dropped off its oxygen to the organs.
Blood is pumped from the heart to the rest of the body by way of arteries which get smaller and smaller until they reach capillary beds. Then off the capillary bed small veins become larger and larger veins and finally lead to the heart. From there the blood is pumped to the lungs by arteries and back to the heart by veins where it all starts over again.
Yes, larger arteries branch off into smaller arteries known as arterioles.
Carotid arteries supply blood to brain . Blood is supplied to the entire brain by 2 pairs of arteries: the internal carotid arteries and vertebral arteries. The right and left vertebral arteries come together at the base of the brain to form a single basilar artery. The basilar artery joins the blood supply of the internal carotid arteries in a ring at the base of the brain. This ring of arteries is called the circle of Willis. The circle of Willis provides a safety mechanism...if one of the arteries gets blocked, the "circle" will still provide the brain with blood.
Coronary arteries. The orifice of the coronary arteries are located on proximal part of the ascending aorta, and there are two orifices branching into the left and right coronary arteries.The marginal, anterior and ventricular arteries provide the cardiac muscle with oxygenated blood.The coronary arteries are the major vessels bringing blood to the heart muscle. The are the left and right coronary arteries, the left having a common trunk followed by the circumflex and anterior descending branches. Each of these give off side branches which bring blood and hence oxygen to the heart muscle. Coronary arteries fill during diastole.There is a right coronary artery and the left coronary artery. In total there are four coronary arteries.
The arteries are the blood vessels which take oxygenated blood from the heart and to the rest of the body. The main artery is the aorta which then branches off into smaller arteries, then these eventually break off into even smaller vessels called arterioles which contol the amount of blood supplied to individual tissues. From arterioles branch capillaries which arethe site of exchange between the blood and the cells. Once the body tissues have used all the oxygen and nutrients in the blood, it is returned to the heart by the veins. The aorta aids in pumping because it is highly elasticated and so acts like a capacitor. It takes all the blood form the ventricle as a burst which stretched its walls out. The walls then squeeze back down pushing the blood along more continuously.
