The three branches off the aortic arch are
Which of the following is the correct sequence of branching off the aortic arch
Left Subclavian
left common carotid artery
left subclavian artery
The brachiocephalic artery is the first major branch off of the aortic arch, it gives rise to the right internal carotid artery and the right subclavian artery. The brachiocephalic artery is also sometimes called the brachiocephalic trunk, and may also be called the innominate artery.

cause it supplies blood to more parts of the heart, the higher up the branch the lesion is the more branches downstream that get cut off if it occludes.
The first vessels that branch off the aorta are called the coronary arteries. These arteries are so important for the heart muscle to work properly that they are the first off the aorta.These arteries give blood to the heart muscle itself. These arteries are also called coronary arteries because they form a crown around the top of the heart with the arteries forming an upside down crown.
A stick is a stem from a branch that has no life in it. When a stem breaks off from the branch it becomes dry and easier to break as it decomposes.
brachiocephalic artery
Trick question.... you only have 1 brachiocephalic trunk. It comes off the right side of the aortic arch (right side from anatomical position, or the patient's perspective) and immediately splits into the subclavian artery and the common carotid artery. On the left side of the arch the subclavian and common carotid branch directly off the aortic arch. Hopefully this makes sense.
The brachiocephalic artery is a branch off of the aortic arch and send blood to the head, neck, and right arm.
The brachiocephalic artery divides into the right common carotid artery and the right subclavian artery.
The aortic arch is the area in which the aorta bends in order to descend into the body. It also gives way to three major blood vessels. Thus, the "functions" of the aortic arch are:To bend back the main vessel in order to reach the part of the body below the heart itself;To give off 3 major arteries: the brachiocephalic artery, left common carotid artery, left subclavian artery.
The abdominal aorta splits caudally into the external iliac arteries, and a short section of the aorta continues on and then divides to form the two internal iliac arteries and the caudal artery. There is no common iliac artery in cats as there is in humans. In cats, the caudal artery takes blood to the tail
The aorta. This leaves the heart (left ventricle) loops over (aortic arch) and becomes the descending aorta. Their are other arteries that branch off along the way, carotid, brachial, etc. then the aorta splits into the femoral arteries.
There is an article in Wikipedia on the subject - This is a direct quote... "There is no brachiocephalic artery for the left side of the body. The left common carotid, and the left subclavian artery, come directly off the aortic arch. However, there are two brachiocephalic artery" See the related link for the full article.
DefinitionAortic arch syndrome refers to a group of signs and symptoms associated with structural problems in the arteries that branch off the aortic arch. The aortic arch is the top part of the main artery carrying blood away from the heart.Alternative NamesSubclavian artery occlusive syndrome; Carotid artery occlusion syndrome; Subclavian steal syndrome; Vertebral-basilar artery occlusive syndromeCauses, incidence, and risk factorsAortic arch syndrome problems are most often associated with trauma, blood clots, or malformations that develop before birth. The arteries' defects result in abnormal blood flow to the head, neck, or arms.In children, there are multiple types of aortic arch syndromes, including:Congenital absence of a branch of the aortaIsolation of the subclavian arteriesVascular ringsSymptomsSymptoms vary according to the affected artery, but may include:Neurological changes such as: DizzinessBlurred visionWeaknessBlood pressurechangesBreathing problemsNumbness of an armReduced pulseTransient ischemic attacksTreatmentSurgery is usually required to treat the underlying cause of aortic arch syndrome.ReferencesWebb GD, Smallhorn JF, Therrien J, et al.

Three arteries come off the Aortic Arch (from left to right) 1. Brachiocephalic Artery 2. Left Common Carotid Artery 3. Left Subclavian Artery. Then After the Aorta arches it then descends behind the heart and turns into the Descending Aorta which is then classified as either the Thoracic Descending Aorta or the Abdominal Descending Aorta.
Parts of the body supplied by arteries that branch off the aortic arch before the narrowing have high blood pressure, while most of the lower body does not receive enough blood supply. To compensate, the heart works harder, and the blood pressure rises
The right coronary artery takes its blood supply from the right coronary sinus, just above the aortic valve and sprouting from the ascending aorta. The left coronary artery takes its blood supply from the left coronoray sinus, also coming off of the ascending aorta. From these main coronary arteries, the rest of the branch coronary arteries are derived.
