Should we know exactly about the 'Elastic Arteries', which are essential for the blood circulation in our body?

Have you ever wondered how our heart pumps blood throughout our body? The heart doesn't just pump blood continuously, it stops for a moment and then pumps again. Even then, there is a special type of blood vessel that helps keep the blood flowing in the same direction. We call them 'elastic arteries'. They get their name because they stretch and contract like a rubber band.

What are these 'Elastic Arteries'?

Simply put, 'elastic arteries' are large blood vessels that are very flexible, meaning they bend easily and stretch. Your heart pumps blood in a rapid, jerky motion. A large amount of blood comes out at once, followed by a short rest. But the cells in our body need a continuous flow of blood. These elastic arteries help to withstand the pressure of the blood that comes from the beating heart and keep the blood flowing smoothly. Imagine that when you turn on a water tap, the water flows quickly. That's how blood flows from the heart. These elastic arteries act like a 'shock absorber' , reducing that pressure and sending the blood to other smaller blood vessels.

What are examples of elastic arteries? Where are they located?

Okay, so what are these elastic arteries? The aorta , which is the largest blood vessel in our body, is a major elastic artery. It's like a big water pipe. In addition, the pulmonary arteries , which carry blood to the lungs, also belong to this type.

Now let's see where these are located. These elastic arteries are located very close to the heart .

• The aorta starts above the heart and runs behind and below it. It is connected to the left side of the heart by a valve called the aortic valve. This valve is where oxygen-rich, clean blood enters the aorta and begins to travel throughout the body.
• The other elastic arteries branch off from this aorta, like small roads branching off from a large road. These are mainly located in the upper part of your chest:
• Brachiocephalic artery: This begins at the aortic arch.
• Subclavian arteries (right and left): These are located near your collarbones.
• Common carotid arteries (right and left): These are the main blood vessels on either side of the neck.
• Common iliac arteries (right and left): These branch off from the lower part of the aorta, that is, from the abdominal region.

• The Pulmonary Arteries are located just above the heart. They are connected to the heart by a valve called the pulmonary valve on the right side of the heart. This is where oxygen-poor blood is sent to the lungs, where it is oxygenated.

What service do elastic arteries provide to our bodies?

So, what exactly does this elastic artery do? They are essential to our lives . These elastic arteries do a great job of carrying oxygen and nutrients to every cell in our body. Imagine, the heart pumps a large amount of blood at high pressure. These elastic arteries must be able to withstand that high pressure and volume of blood .

Simply put, these are like the big main water pipes that bring water to your village. From those big pipes, the water is divided into smaller pipes that bring water to your houses. Just like that, these elastic arteries take blood and divide it into other small arteries (muscular arteries). From those small arteries, the blood goes to even smaller blood vessels (capillaries) where the cells get oxygen.

It's important to remember that while all the other arteries in our body carry oxygenated blood, only the Pulmonary Arteries carry deoxygenated blood . Their sole function is to carry that deoxygenated blood to the lungs, where it is replenished with oxygen, and then back to the heart.

How are elastic arteries formed? What do they look like and how big are they?

Now let's take a look at what's inside these elastic arteries and how they're formed. Like other blood vessels, elastic arteries have three main layers .

• The outermost layer ('Adventitia'): This is where the artery gets its strength and structure.
• Tunica Media: This is the most special part. This layer contains both elastic tissue and muscular tissue . However, in elastic arteries, this middle layer has more elastic tissue than muscular tissue . That is why it is called 'elastic'. These elastic fibers are what allow the artery to stretch and contract well.
• The innermost layer (Tunica Intima): This is very smooth. This layer is designed to allow blood to flow easily and without any obstruction.

These elastic arteries contain a protein called collagen and small muscle fibers. These are what help the artery walls stay strong and flexible.

So how do these look?

Elastic arteries are like large, cylindrical tubes. They're hollow in the middle, and that's where the blood flows. But the aorta is a little different. It's described as like a big candy cane with two legs.

How big is it?

The largest elastic artery in our body, the aorta, has an internal diameter of about 2.5 centimeters (that's almost an inch). The wall of the aorta is about 2 millimeters thick. Imagine how strong that must be!

What are the common diseases and conditions that affect elastic arteries?

Sadly, even these important elastic arteries can develop various diseases. Let's see what they are:

• Aneurysm: This is when the wall of an artery weakens and bulges like a balloon. This is very dangerous because it can burst.
• Dissection: This occurs when the layers of the artery wall tear from within, causing blood to leak between those layers.
• Valve problems: Leaks or stiffness in the aortic valve or pulmonary valve.
• Congenital heart diseases: These are heart diseases that are present at birth. Sometimes these can affect the aorta or pulmonary arteries.
• Vasculitis: This is inflammation of the blood vessels.
• High blood pressure: This is a problem that many people have. High blood pressure can damage the arteries.
• Atherosclerosis: This is when fats like cholesterol build up inside the artery walls, causing them to become narrow. This is a major obstacle to blood flow.
• Blood clots: If blood clots form inside an artery, blood flow can stop completely.
• Heart failure: When the heart becomes weak, it also affects these arteries.

So what are the symptoms of this condition?

These diseases can present with different symptoms. Not everyone will experience them in the same way. However, here are some common symptoms:

• Fast heartbeat
• Feeling dizzy (Lightheadedness)
• Headache
• Feeling tired all the time (Fatigue)
• Chest pain
• Heart palpitations
• Shortness of breath
• Leg cramps during a walk

How do doctors check the health of these elastic arteries?

If you have these symptoms, you should see a doctor. He or she can perform various tests to check the condition of your elastic arteries.

• Blood tests: Check things like cholesterol levels and sugar levels.
• Angiogram: In this, a special dye is injected into the blood vessels and an X-ray is taken to see if there is any blockage or blockage anywhere in the blood vessels.
• MRI (Magnetic Resonance Imaging): Uses magnetic fields and radio waves to take detailed images of the inside of the body.
• 'CT Scan' (CT - Computed Tomography): This is the same as `X-ray` technology, but images are taken from different angles and combined on a computer to produce a clear image.
• Ultrasound: Uses sound waves to produce images of blood vessels.
• Echocardiogram: This is an ultrasound test of the heart. It can check the function of the heart and the condition of the valves.
• Chest X-ray: See the size and shape of the heart and lungs.
• 'EKG - Electrocardiogram': Tests the electrical activity of the heart.
• Cardiac catheterization: A small tube (catheter) is passed through a blood vessel into the heart to measure the pressure, and if necessary, an angiogram is also performed.

What are the treatments for such diseases?

The best thing is, there are treatments for most of these diseases that affect elastic arteries. It varies depending on the nature and severity of the disease. There are two main treatment methods:

• Medications: Doctors prescribe medications for things like high blood pressure, lowering cholesterol, preventing blood clots, and reducing pain.
• Surgery: In some cases, for example if an aneurysm has grown large or an artery is severely blocked, surgery may be necessary. This may involve removing the damaged part and inserting an artificial tube (a graft) or inserting a stent to widen the blocked area.

What are some simple things we can do to keep our elastic arteries healthy?

This is the most important part. Isn't it better to prevent an illness before it happens than to suffer after it happens? So, the habits that are good for our heart and blood vessels are also good for these elastic arteries.

• Eat a low-fat, low-salt diet: Reduce your intake of oily, fried, and sweet foods as much as possible. Eat more vegetables, fruits, legumes, and whole grains.
• Exercise regularly: Do something like walking, running, or swimming for at least 30 minutes a day.
• Control high blood pressure: If you have high blood pressure, take the medication your doctor prescribes exactly and live your life as directed.
• Control high cholesterol: This also involves diet and, if necessary, medication.
• Avoid smoking completely: Smoking is very harmful to blood vessels.
• Manage stress: Too much stress is not good for the body. Relax your mind with things like yoga and meditation.

What is the main difference between 'elastic arteries' and 'muscular arteries'?

We've talked about this a little bit before. Elastic Arteries are the large arteries closest to the heart. They have the most elastic tissue in their middle layer (the tunica media). That's why they can stretch so well.

Muscular Arteries are smaller arteries that branch off from elastic arteries. Their middle layer is mostly made up of muscle tissue . The contraction and relaxation of these muscles control the amount of blood flowing to different parts of the body. Simply put, elastic arteries support blood pressure, while muscular arteries help distribute blood.

So, what is the final thing to remember? (Take-Home Message)

So, now you understand how important these 'Elastic Arteries' are to our bodies. The service they perform is no small one, bearing the pressure of the blood coming from the heart and sending that blood, along with oxygen, to every cell in the body.

Therefore, taking good care of your elastic arteries is a great investment you make in your overall health.

If you keep them healthy, your body will get the blood it needs without any problems. That means you can stay healthy and happy. So, let's all take care of our blood vessels, right?
