In this chapter, we discuss blood flow through arteries and veins, making use of the fluid mechanics principles that were derived in earlier chapters. First we highlight the anatomy and physiology of arteries, arterioles, veins, and venules. The function of the venous valve system is discussed...
This slow flow rate allows more time for exchange processes to occur. As blood flows through the veins, the rate of velocity increases, as blood is returned to the heart. Disorders of the Cardiovascular System: Arteriosclerosis Compliance allows an artery to expand when blood is pumped through ...
emissary veins were occluded with bone wax to prevent communication between the intracranial and extracranial venous circulations. From the confluence of sinuses the blood then passed through a previously calibrated electromagnetic flow probe, before returning to the dog via the femoral vein (Fig. 1)....

The difference is that the walls of the veins are not elastic and thinner than the arteries. This is because the veins do not face the blood pressure pumped out by the heart. When the blood is returned to the heart through the veins, the blood has to flow against gravity. The valves ...
aneurysm is the expansion of an artery brought about by frailty in the arterial wall. Blood flow through veins turns out to be more confounded as aneurysm develops. Catheterization is now the most standard medical method for diagnosing and treating arterial diseases. A catheter is a dainty, empty...
Veins also contain a structure called valves which prevent the backflow of blood due to the pull of gravity. These venous valves are mainly found in medium to large veins.BLOOD FLOW THROUGHOUT THE BODYThe blood vessels are the channels that transport blood thus, they also allow blood to flow...

smooth muscle in the blood vessel walls keep them from expanding too much. Following a contraction of the heart, arterial pressure decreases as the vessels relax. Because of their thick elastic walls, arteries are able to cycle through contraction and relaxation to provide a steady flow of blood...
Over time, uncontrolled hypertension can damage blood vessels throughout the body, including those in the brain. This vascular damage can lead to various cognitive impairments and an increased risk of dementia. Hypertension results in decreased blood flow to the brain, depriving it of essential oxyge...
