Our heart is like a water motor, isn't it? It works non-stop, pumping blood throughout the body. But have you ever wondered, when the heart suddenly pumps blood with great force, who helps to bear that pressure and keep the blood flowing smoothly? That's where the heroes of our story, namely the special type of blood vessels called 'Elastic Arteries', come to the rescue. Today, let's talk about these silent workers in our body.
Simply put, what are elastic arteries?
Imagine you are holding a water pipe in your hand. One is a hard plastic pipe, and the other is a flexible rubber pipe. Now, what happens if you send a large amount of water through both of these pipes at once? The hard plastic pipe cannot withstand the pressure and may even burst. But the flexible rubber pipe, when the water comes in, inflates a little, and then returns to its original size and sends the water forward by the same amount.
These elastic arteries work like rubber tubes. When the heart beats, these arteries expand a little to accommodate the high pressure of the blood that is pumped out suddenly. Then, when the heart relaxes for a moment, these expanded arteries return to their original position and push the blood forward. This is why, even though the heart is pumping blood, blood flows to the rest of our body at the same smooth speed. This is because of this elasticity of these arteries.
What are the main elastic arteries in our body?
These are the largest arteries in our body and the ones closest to the heart. They are like main roads. These main roads branch off into smaller side roads. Similarly, blood branches off from these larger arteries into smaller arteries.
| Artery Name | A simple explanation |
|---|---|
| Aorta | The largest artery in our body. It is the main tube that starts on the left side of the heart and distributes oxygenated blood throughout the body. |
| Pulmonary Arteries | Starting from the right side of the heart, oxygen-poor blood is carried to the lungs. It is from the lungs that this blood is re-oxygenated. |
| Brachiocephalic Artery | It branches off from the aorta and supplies blood to the head, neck, and right arm. |
| Common Carotid Arteries | It goes up the neck on both sides and supplies blood to the brain and face. |
| Subclavian Arteries | It is located under the collarbone and carries blood to the arms. |
| Common Iliac Arteries | The aorta divides into two in the abdomen and carries blood to the legs. |
Most importantly, these arteries are like highways that carry oxygen and nutrients throughout the body. Their health directly affects our overall health.
How are these arteries formed?
Like other blood vessels, this one has three main layers, like applying several coats of plaster to a wall.
| Layer | Task |
|---|---|
| The outermost layer (Adventitia) | This is the outer covering that gives the artery strength and shape. |
| Middle layer (Tunica Media) | This is the most important part. It contains both elastic fibers and muscle fibers. In elastic arteries, there are more elastic fibers than muscle. |
| Innermost layer (Tunica Intima) | This is very smooth, so the blood can flow without any blockages or clots. |
Difference between elastic and muscular arteries
Simply put, elastic arteries are the main arteries near the heart that have to withstand high pressure. Muscular arteries are smaller arteries that branch off from those main arteries and distribute blood to various organs of the body. They do not experience as much pressure. Therefore, they have more muscle fibers than elastic fibers in their middle layer. The muscles contract and relax to control the amount of blood that goes to each organ.
What diseases can affect these arteries?
These large arteries can also be affected by various medical conditions, some of which can be very serious.
| Medical condition | A simple explanation |
|---|---|
| Aneurysm or Dissection | Aneurysms, or a tear in the wall (dissection), can be life-threatening. |
| Valve problems | The aortic valve or the pulmonary valve, which is located between the heart and the aorta, may not close properly (leak) or may become tight. |
| Atherosclerosis | Cholesterol and other substances build up in the artery walls, narrowing the passage of blood. This is the root cause of many heart diseases. |
| High Blood Pressure | Constantly high pressure inside the arteries can cause the arteries to lose their elasticity over time, causing them to become stiff. |
| Blood Clots | Blood clots can become lodged inside the arteries and completely block blood flow. |
What are the symptoms to watch out for?
Often, problems with these arteries don't show symptoms in the early stages. But as the condition progresses, you may experience symptoms like:
- Chest pain: A squeezing, squeezing pain.
- Difficulty breathing: Wheezing even when walking a short distance.
- Palpitations: A feeling of your heart beating rapidly, even when you are just standing still.
- Dizziness or lightheadedness: especially when standing up.
- Sudden, severe headache.
- Pain in the back of the legs when walking: It subsides after a short rest, but comes back when walking.
- Constantly feeling tired.
If you have these symptoms, don't dismiss them as normal. It's important to see your doctor immediately for advice.
What can we do to keep these precious arteries healthy?
The best part is, the things we do to keep our arteries healthy are good for our entire body. These are not difficult things. Small things can make a big difference.
- Healthy eating: Reduce your intake of foods high in oil, salt, and sugar (especially junk food and packaged foods) . Instead, include fruits, vegetables, legumes, and whole grains in your diet.
- Regular exercise: Get at least 30 minutes of moderate-intensity exercise a day. Brisk walking, running, or cycling are all good options.
- Avoid smoking completely: Smoking is one of the biggest culprits in damaging your arteries. It can harden the walls of your arteries, increasing your risk of blood clots.
- Control your blood pressure and cholesterol: If you have high blood pressure or high cholesterol, take your medication exactly as prescribed by your doctor. It is also important to control your diet.
- Manage stress: Excessive stress is also not good for our blood vessels. Relax your mind by doing things like meditation, yoga, and engaging in a good hobby.
- Regular medical checkups: If you are over 40 years old, it is very important to see your doctor at least once a year to check things like blood pressure, sugar, and cholesterol.
If you incorporate these simple habits into your life, not only your heart, but also these precious elastic arteries will serve you healthily for a long time.
Take-Home Message
- Elastic arteries are like a super-flexible tube system that can withstand the high pressure from the heart and smoothly transport blood throughout the body.
- The aorta and pulmonary arteries are the most important of these.
- A good lifestyle (good diet, exercise, and avoiding smoking) is essential to keeping these arteries healthy.
- If you have symptoms like chest pain, difficulty breathing, or nausea, don't ignore them and see your doctor immediately.
