"We're going to talk about morphology of blood vessels. Morphology, first of all, means study of a form or structure. Now, if you were to look at a blood vessel, it looks tubular in nature. It just looks almost like a telescope that has parts that just kind of fit over top of each other. It's tubular in nature. There are layers. There's inner layers of the blood vessel. There's collagen which will stretch and has elasticity to it. There's a surrounding vessel and then there's connective fibers. You might find that loss of elasticity, that stretching ability, tends to result with increased blood pressure and especially in older people and those with diabetes. The connective tissue prevents ballooning. Now, many of you might already know that ballooning is another way of talking about an aneurysm. When you lose the loss of the elasticity of the connective tissue and it begins to balloon out, it bubbles, and when it does, it can cause an aneurysm, which can be a fatal disorder."
