Aortic Aneurysms and Venules


Your heart and body are surrounded by arteries. Aorta is the main artery. It connects to the left side of your heart and runs through your chest, abdomen, and pelvis. It branches off into smaller arteries near the pelvis and legs. These arteries carry blood from your heart back to your legs. Venules are the smallest arteries. They connect the veins and capillaries in your body.

As you age, the arteries in your heart become more likely to harden and narrow. This condition is caused by the buildup of fatty substances on the artery walls. The result is that the arteries narrow and stiffen, making it difficult for blood to pass. Over time, pieces of plaque can move to smaller blood vessels, starving them of oxygen and causing a heart attack. Many people develop coronary artery disease and suffer heart attacks from atherosclerosis. However, high blood cholesterol increases your risk of hardening arteries.

An artery has three layers: the innermost tunica intima is made of a lining and a fine network of elastic fibers and connective tissue. The middle layer, the tunica media, is made up of smooth muscle cells and collagen fibres arranged in spiral layers. Larger arteries have thicker tunica media and adventitia than smaller ones. A physical exam will help determine the type of blockage in an artery.

Your arteries supply vital nutrients and oxygen to your body. Besides regular exercise, a healthy diet, and a low-fat diet will keep your arteries flowing. It’s important to understand your arteries’ function and make sure they are flowing as smoothly as possible. Early signs of high blood pressure and cholesterol should be treated by your healthcare provider. They can even perform a blood pressure test to determine if they are normal or abnormal.

Coronary artery disease can result in a heart attack, stroke, or even death. High blood pressure and smoking are risk factors for coronary artery disease. Also, an autoimmune disease may increase your risk of atherosclerosis. Symptoms of coronary artery disease include chest pain and shortness of breath. If left untreated, this condition can lead to a heart attack or a stroke. So, it’s important to consult a doctor as soon as possible.

The doctors will discuss your symptoms and assess the extent of the problem. Some medications can prevent the occurrence of blood clots. You may also need surgery. If you think you have an artery disorder, you can try lifestyle changes to reduce your risk. If the symptoms are too severe, your doctor may suggest medication or surgery to treat the condition. Make sure you have written down all of your questions and concerns before your appointment.

The difference between an artery and a vein is that veins do not have thick walls. The pressure in veins is lower than in arteries, which makes it easier for them to flow. In addition to arteries, veins are often referred to as capillaries. Those veins in the legs have valves that prevent blood from flowing backward. The heart is responsible for pumping oxygenated blood into the aorta, the largest artery in the body. Smaller arteries branch off from the aorta, eventually feeding the entire body.
