A flow void is a place in the artery that's not showing any blood flow. Dominant suggests that there's one major area of missing flow.

The basilic artery in the brain receives blood from what two arteries?
The left & right vertebral arteries.
What are the pathway of a drop of blood from the aorta to the left occipital lobe of the brain and What are the structures through which it flow?
The drop of blood travels as follows: From the aortic arch to the left subclavian artery. Then through the left vertebral, passing though the transverse foramina of the cervical vertebrae (from C6-C1) At the C1 level the vertebral arteries travel across the posterior arch of the atlas before entering the foramen magnum into the skull. From here, it merges with with that vertebral artery on the right side to become the basilar artery. The blood then travels through a branch of the basilar known as the posterior cerebral artery. This artery's branches are divided into two sets, the ganglionic branches and, the cortical branches. The particular artery largely supplying the occipital lobe is known as the parietoöccipital or parieto-occipital artery, and is a cortical branch.
What three vessels does blood from the celiac artery flow into?
Splenic Artery, Left Gastric Artery, and Hepatic Artery
What is the main artery that takes blood to the brain?
The left and right corotid arteries and the vertebral arteries which join together to form the basilar artery (forming the circle of willis).
What are the effects of your left vertebral artery not connecting to your basilar artery?
If the Circle of Willis can still maintain at least 50% blood pressure with the blood flow from the one good artery, then no infarctions will occur. Patients with blockage in the LVA can exist with no visable signs of illness as long as the otra continues to function properly. If the remaining VA enlarges as a result of increased blood flow, a transient ischemic attack may result, temporarily depriving the brain of oxygen. Because the patient is now without a backup system, they are more at risk of a stoke when exhibiting low blood presure, hypertension, or arteriosclerosis. Of course, if the left vertebral were severed via trauma, it would require surgery to repair because of the bleed into the brain would cause swelling and brain trauma.
What are the consequences of having a developmentally diminutive left vertebral artery?
Blood flows to the brain through the left vertebral artery. The consequences or risks of having a developmentally diminutive left vertebral artery is the risk of stroke.
Left vertebral artery is hypoplastic and ends as PICA?
This is a normal anatomic variant.

Which vessel is formed when the vertebral arteries join together at the base of the skull?
The right and left vertebral arteries join together to form a single basilar artery at the base of the skull.
What is the main artery that takes blood to the brain?
The left and right corotid arteries and the vertebral arteries which join together to form the basilar artery (forming the circle of willis).
What is the main blood vessel that goes to the brain?
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.
How is the flow of blood different to the left arm?
Ascending Aorta-->Arch of the Aorta--> Brachiocephalic Trunk--> Left Subclavian Artery--> Left Axillary Artery--> Left Brachial Artery--> Left Radial-Ulnar-Palmer Arteries . How is the flow of blood different to the right arm? Merely exchange the "left" with "right" :) Reference: A & P ll Blood Vessels
Artery that supplies blood to the heart wall?
The two main vessels that arise from the Sinus of Valsalva, located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle. Finally, the posterior descending artery can arise from either the right or left coronary artery. If the posterior descending artery arises from the right coronary artery, the heart is termed right heart dominant, which is seen in approximately 70% of individuals. If the posterior descending artery arises from the left circumflex artery, it is termed left heart dominance. It is also possible for the posterior descending artery to arise from both the right and left coronary artery. In this configuration, the heart is considered co-dominant. The posterior descending artery mainly supplies the inferior wall of the left ventricle and the inferior portion of the septal wall.
Trace the arterial blood flow from the heart to the right thumb?
Blood flows from the heart to the arteries and then from the arteries to the
