Choose the arteries in the order that an erythrocyte passes through traveling from the aorta to the brain: (1) Basilar artery, (2) Brachiocephalic artery, (3) Circle of Willis, (4) Right subclavian artery, and (5) Right vertebral artery.

2-4-5-1-3

Explanation:

As the blood leaves the aorta, it branched into the Brachiocepahilc artery. which opens directly into it. The branchiocepahalic arteries further leads to two branches the right subclavian artery and the right common carotid, It i s through this branches that the brachiocephalic supplies the o the neck and right upper limbs with blood containing erythrocytes.

At the neck the R. subclavian arteries empty into the Right vertebral artery; for the erythrocytes to reach the posterior part of the brain, the cerebellum, brain stem, and superior aprt of the spinal cord.

At the base of the skull in front of the brain stem, the vertebral artery joined to form the Basilar artery which emerges at the junction between the medulla and pons. The vertebral artery therefore empty its contents into the Basilar artery. The latter branched off posterioly to form the right and left posterior cerebral arteries; through which it supplied blood to the Circle of Willis. (The vertebral, the basilar and its branches from the Vertebrobasillar System)

The Anastomoses (joining of openings of vessles) of 5 communicating arteries formed the Circle of Willis. They collectively bridged blood cir circulation and communication between the forebrain and the hindbrain for the RBC to reach the brain.

The sequence order of the arterial vessels in the order leading from the aorta to the brain is: 2,4,5,1,3.

Explanation:

Correct Answer: In order, the sequence of vessels leading from the aorta to the brain is: 2,4,5,1,3.

2 - The brachiocephalic artery (same as brachiocephalic trunk and innominate artery) is an artery found in the mediastinum region where blood is supplied to the right arm and the head and neck

4 - The right subclavian artery arises from the arch of the aorta directly which is a branching of the brachiocephalic trunk and is on the left lies posterior to the insertion of the scalene muscle anterior on the first rib.

5 - The vertebral arteries are arteries majorly of the neck. Usually, this arteries originate from the subclavian arteries. It functions so as to supply the vertebrobasilar vascular system, thks vertebral arteries supply blood in this order to the upper spinal cord, brainstem, cerebellum, and posterior part of brain.

1 - Meanwhile basilar artery carries oxygenated blood from 5 to the cerebellum, brainstem, and occipital lobes.

3 - Several arteries at the bottom (inferior) side of the brain is called Circle of Willis and it is the joining area of several arteries in the brain. Branching of smaller arteries from the Circle of Willis happens here as internal carotid arteries that supply oxygenated blood of more than 80% of the cerebrum.
