Question
Answer the following questions about the vasculature of the brain. Arteries carry blood in what direction in the body? Veins carry blood in what direction in the body? Be able to explain the redundant arterial blood supply to the brain. Be able to follow arterial blood from the neck to the brain, through the Circle of Willis, and into the middle cerebral arteries. . . . Be able to follow venous blood flow out of areas of the brain into the two interna jugular veins. Blood primarily enters the brain through what 3 bony apertures in the skull? Blood primarily leaves the brain through what 2 bony apertures in the skull?Sy . Locate on a skull the specific sulci where the dural venous sinuses travel. Know the names of the venous structures travelling in each of the sulci. What is the blood brain barrier (BBB)? .Explanation / Answer
1.
Arteries carry oxygenated blood away from heart. The arteries are responsible for supplying blood
to whole body. As heart pumps blood with such a great pressure,in arteries,blood flows towards right direction.
(relating to heart)
The muscles of arteries allow bloodto flow in a single direction.
2.
Veins carry deoxygenated blood to heart. The veins are responsible for collecting blood
from whole body. As heart recieves blood with such a great pressure,in veins blood is carried in left direction.
(relating to heart)
The muscles of veins allow blood to flow in both directions.
