Question

What three arteries branch off the aortic arch?

Answer 1

Hint: The blood vessels that transport oxygen-rich blood from the heart to the body's tissues are known as arteries. Each artery is a muscular tube with three layers of smooth tissue lining it.

Complete answer:
The human heart is made up of four chambers, two atria and two ventricles, with the atria receiving blood and the ventricles pumping it. The right atrium receives blood from the superior and inferior vena cava, as well as the coronary sinus; the blood is then pumped to the lungs by the right ventricle.
The segment of the aorta between the ascending and descending aorta is known as the aortic arch. The arch runs slightly backward and to the left of the trachea as it emerges from the ascending aorta.
The aortic arch lies between the second sternocostal joint and is a continuation of the ascending aorta. Before going inferiorly, it arches superiorly, posteriorly, and to the left.
The aortic arch assists in the distribution of blood to the head and upper extremities through the brachiocephalic trunk, left common carotid, and left subclavian artery. Baroreceptors located inside the walls of the aortic arch play a role in blood pressure homeostasis as well.
The brachiocephalic artery, the left common carotid artery, and the left subclavian artery, are the three branches of the aorta's arch. Both the arms and the head receive blood from these arteries.
The brachiocephalic artery, also referred to as the brachiocephalic trunk or the artery , may be a mediastinum artery that supplies blood to the proper arm, head, and neck. It is the aortic arch's first branch. The fifth branch of the aorta and therefore the third branch from the arch of the aorta is that of the left arteria subclavia . The brachiocephalic artery and its branches give rise to the right subclavian artery.
The main blood supply to the head and neck is provided by the Common Carotid artery, which is a long elastic artery. The carotid arteries are the main blood vessels that supply the brain and face with oxygen and nutrients.
The fifth branch of the aorta and the third branch from the arch of the aorta is the left subclavian artery. The blood supply to the left arm is provided by the left subclavian artery.

Note:
Students may have problems in memorising the different branches of the aorta. Therefore, it is important to first learn the basic position of the major arteries and then their functions and connections will become clear.
