To start, the term cardiovascular disease actually includes a bunch of different diseases, and there are many factors that go into what causes each kind. And the structure we need to learn to understand these diseases isn’t necessarily the heart, but rather the arteries.
Arteries are complex, ever changing organs that deliver blood throughout the body and play a role not just in disease, but in experiencing different climates, exercising, and maintaining homeostasis.
When you take a big picture look at the entire cardiovascular system, you will see two distinct loops of blood vessel networks, shaped like a figure eight. One of the loops carries deoxygenated blood from the right side of the heart to the lungs, picks up some oxygen, and circles back to the heart.
This pulmonary circulation is where important gas exchange happens, allowing us to utilize all the carbon dioxide waste we’ve built up in our blood and capture that oxygen we breathe in.
Once our blood is nice and oxygenated it comes back to the left side of the heart to be pumped into systemic circulation, the second loop that hits everything that isn’t the lungs.
Right after getting ejected from the left side of the heart, blood then passes through the aorta, which is the biggest artery the human body has.
The aorta branches off into smaller arteries up into the neck and brain and down the body into the limbs and abdomen. As the arteries get closer to individual tissues and organs, they’ll branch off into tiny arterioles, and then into microscopic blood vessels called capillaries.
Some of those capillaries are so tiny that red blood cells have to line up cell by cell to get through.
But, no surprise, not all of our arteries are built the same.
Find out more about your different arteries, the purposes they serve, and how they all come up again and again when it comes to understanding cardiovascular disease in this episode of Human.

The top 10 causes of death

“Of the 56.9 million deaths worldwide in 2016, more than half (54%) were due to the top 10 causes. Ischaemic heart disease and stroke are the world’s biggest killers, accounting for a combined 15.2 million deaths in 2016. These diseases have remained the leading causes of death globally in the last 15 years.”
Nanoparticle helps eat away deadly arterial plaque

“Atherosclerotic plaque-deposits on the inner walls of arteries are a frequent cause of heart attacks and strokes. A newly-developed nanoparticle could help minimize those deposits, as it prompts the body's own cells to "eat" them.”
Mystery of why arteries harden may have been solved, say scientists
www.theguardian.com/science/2019/jun/11/mystery-ar…
“The mysterious mechanism behind the hardening of arteries may have been solved, researchers have revealed, in a study that also suggests the first potential preventive drug for the condition linked to heart attack, dementia and stroke. Arteries harden as calcium becomes deposited in the elastic walls of the vessels, a process that happens as we age and is exacerbated for patients with diabetes or kidney disease.”

Hi Seekers, thanks for watching! Want to learn more about the human body? Check out this video on all the different blood types: https://youtu.be/Ti3Ig6b7T1g

6:55 "but no matter what causes the dysfunction"... well, that's exactly why we're watching this video, it was posed as the question 'Why Do Arteries Get Clogged?' it feels like they said 'smoking, high blood pressure and diabetes' causes clogs in one sentence and there's less nitric oxide with smoking, but they should go further in explaining how high blood pressure and diabetes (are there more causes?) are answers to the original question
-
This was more of a crash course anatomy circulatory video than answering the reason for arteriosclerosis. Even then, still information and well made! Title mislead though
-
I have clogged arteries in my legs. The doctor gave me two choices: stents or walking. He sent me to therapy where they had me walk 1 mile a week. I was already walking 2.5 to 5 miles a day! It's finally paying off. The body is designed to move, don't wait for all the things that can happen with a sedentary life, get out and move your body daily. A little is better than nothing.

Aight time to exercise
-
I learned about the cardiovascular system at university and came here to understand how arteries get blocked, what causes it exactly and if it has some kind of treatment. I only relearned the basics of the cv system and didn't really get what causes the clots. Did i miss something?
-
Made it through the video after almost fainting.
-
This needs to be so much higher. Commenting so the algorithm knows I’m interacting with this video and it should share it more

Acute care telemetry/stroke nurse here waves enthusiastically Thanks for the video! Education is an indispensable part of healthcare. For that reason, I wanted to suggest a minor correction: The definition you gave for ARTERIOsclerosis actually describes ATHEROsclerosis, a more specific ailment and a term more people should be familiar with. The names may look very similar at first glance, however they do refer to different problems within the arterial wall. Arteriosclerosis is a more general term that refers to a hardening, thickening, or general "noncompliance" of the artery. This can in fact occur from atherosclerosis, which as you described is the accumulation of cholesterols, blood products & cells within the vessel wall. But arteriosclerosis is a more general term which can be caused by more factors than just cholesterol accumulation. So while they can both lead to potentially lethal blockages, atherosclerosis has a more specific cause that can help health care providers and patients narrow in on successful interventions. Thanks again!

They didn’t address diet even though it is by far the leading cause.

My uncle was going to get heart transplant surgery, but then he had a change of heart.

i think dr. berg hit the nail on the head the other day when he said you can't fix a fatty liver with exercise. you have to clean up your diet. same goes for the heart. the battle is won at the dinner table
-
I feel this needed more solutions than "just exercise". Also, is it non-reversible ??

Great video for our homeschool health class! Also, excessive sugar & starch cause inflammation in the cardiovascular system that causes the body to react to the damage protectively with plaquing, like an internal scab. One way exercise reduces plaquing is by using up the excessive sugar/starch in the blood & body to reduce chronic high blood sugar. Beware... the USDA Food Pyramid recommends a toxic level of starch/sugar from grains, potatoes, corn, beans, fruit, juice, dairy, concentrated sugars, and highly processed seed oils are also highly inflammatory. The low fat forces high sugar Food Pyramid was designed to feed the masses for lower cost not best health longest life. Carbs are more profitable & taxable jobs too than a low carb natural fats economy. A mostly carbs diet is a mostly inflammatory diet.... increases vulnerability to cytokine storm death from a virus, you know which one I'm talking about. Chronic Carb OD causes the chronic inflammation that causes heart attacks, not natural fats.

Excellent seeker... Loved this informative segment of yours... keep it continued plz...
-
Very informative. Exercise is the magic trick to have a healthy circulatory system. Thanks Doc!
-
It really give me a kick to change something on my diet/living style. Thx!
-
Most of my feelings about this video was already address by other commenters, but I must stress the point that the author / speaker of this video did not provide solution or address the question as to why, how, and ways to fix this clogged arteries. For example, how do you get rid of plaque in the arteries?
-
I noticed how there's no mention of no mention of the effects of oil on the endothelial cells and how that's a major cause for why the plaque builds up there in the first place.
