What are the 3 branches of the aortic arch in order?
The convexity of the aortic arch gives off three branches; the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. Brachiocephalic trunk: also called the brachiocephalic artery, is the first and largest artery that branches off the aortic arch.
What are the 4 arteries that branch from the aortic arch?
The aortic arch is the portion of the aorta that is in the shape of an arch and connects the ascending aorta with the descending aorta. The major arteries that stem from the arch are: the brachiocephalic artery, the left carotid artery and the left subclavian artery.

What are the aorta’s branches?
- Brachiocephalic trunk, which branches into the right subclavian artery (supplies the right arm) and right carotid artery (supplies the brain and right side of the head and neck).
- Left subclavian artery supplies your left arm and the back of your brain.
What is a branch of the aortic arch?
The brachiocephalic trunk is the first branch of the aortic arch and supplies blood to the right arm and right head and neck. The left common carotid artery is the second branch of the aortic arch, which supplies blood to the left side of the head of the neck.
What is the first branch of aorta?
brachiocephalic trunk
The first branch of the aorta is normally the innominate artery, which is also referred to as the brachiocephalic trunk. Shortly after its origin, the innominate artery divides into the right subclavian and right common carotid arteries.

What is the most important artery in the heart?
The heart’s three coronary arteries are not all equal. The most important artery is called the left anterior descending artery (LAD). It feeds blood to the whole front wall of the heart, which represents much more muscle than the area fed by either of the other two coronary arteries.
What are the 5 major arteries of the heart?
The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary …
Which is the smallest vein?
Capillaries. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
What is the smallest blood vessel?
Capillaries
Capillaries are the smallest blood vessels in the body. How small are they? About ten of them equal the thickness of one human hair, and most are so small that only one blood cell can pass through them at a time. Explain that smoking harms your blood cells and blood vessels, including tiny capillaries.
What are the five paired branches of abdominal aorta?
