Aneurysm – A sac-like protrusion from a blood vessel or the heart, resulting from a weakening of the vessel wall or heart muscle.
The shape of an aneurysm is described as being fusiform or saccular, which helps to identify a true aneurysm. The more common fusiform-shaped aneurysm bulges or balloons out on all sides of the blood vessel. A saccular-shaped aneurysm bulges or balloons out only on one side
.Saccular aneurysms, also called “berry” aneurysms because they look like berries, are the most common type of brain aneurysm. Saccular aneurysms have a “neck” that connects the aneurysm to its main (“parent”) artery and a larger, rounded area called the dome. These aneurysms bulge on only one side of the artery wall.

A section of blood vessel wall has become weakened resulting in an increase in the vessel wall diameter of 32%. For this question treat blood as an incompressible non viscous fluid of density 1050 kg m−3. If the vessel normally carries blood at a speed of 1.2 m s−1 then what is the magnitude of the increase in pressure in the bulge in the blood vessel? (to 2 s.f and in Pa)

From superficial to deep, the layers of the blood vessel wall include the: Which of the following correctly describes the role of the smooth muscle cells in the blood vessel wall? They play an important role in determining the amount of blood flowing to a tissue (tissue perfusion). They play an important role in blood pressure. They control the diameter of the blood vessel. All of the above. None of the above.

Given that the velocity of blood pumping through the aorta is about 48 cm/s, what is the total current of the blood passing through the aorta (in grams of blood per second)? B. If all...
