Blood vessel

In a coronary artery bypass, blood vessels from other parts of the body and used to redirect blood flow so that blood can travel to the heart quicker. One issue with this procedure is that if blood vessels from other parts of the body are not suitable for the coronary artery bypass, then a replacement blood vessel must be used. My goal is to make a blood vessel replacement that is durable, strong, flexible, comfortable, interacts well with surrounding cells and tissues, all while being as inexpensive as possible. I believe the best way to achieve this goal is to create my own novel design. I can study existing technologies to see where prior technologies failed or suffered and use my ideas to fix the blood vessel replacement. In tissue engineering,…

Atherosclerosis is the hardening and narrowing of the blood vessels due to a fat and plaque buildup on the vessels. Some of the major risk factors for atherosclerosis include hypercholesterolemia, increasing age, sex- male being more prevalent than females, high blood cholesterol levels, cigarette smoking, obesity, and hypertension, all of which the patient has. (1) There are three main types of lesions associated with atherosclerosis, including fatty streaks, fibrous atheromatous plaques, and…

My heart disease essay is about Coronary artery disease. Coronary heart disease is a disease in a waxy substance called plaque which builds up inside the coronary arteries. The arteries supply oxygen and rich blood to your heart muscle. When plaque builds up in the arteries, the condition is atherosclerosis and the buildup occurs over many years. Coronary heart disease is also a narrowing of the small blood vessels. Coronary artery disease can’t be cured, but treatment may help the disease.…

ischemic stroke patients while standard treatments involving rehabilitation provide some benefits for the recovery during chronic phase. However, many high-profile failures in a wide spectrum of pharmacologic neuroprotection trials have led to some pessimism in the field.[1] Recent findings suggest that enhancement of angiogenesis after focal cerebral ischemia may provide novel opportunities for better outcomes during stroke recovery.[2] Nowadays it is appreciated that new treatment strategies…

responsible for maintaining homeostasis in the body. It is composed of the muscular pumping organ, the heart, and a closed system of vessels called arteries, veins, and capillaries. “A baby 's heart begins to develop at conception, but is completely formed by eight weeks into the pregnancy” (Stanford Children’s Health). As the heart reaches structural and functional maturation, it will involuntarily pump blood to the blood vessels to nourish cells with the oxygen and nutrients they need to carry…

These fragile and exposed blood vessels rupture and leak very easily causing retinal scaring which in turn pulls the retina out of position. These scars usually shrink as they heal and dry causing immense pressure at the retinal conjunction eventually enough pressure tears the lining, completely detaching the retina from its lining. “ROP is a multifactorial disease, and may factors have been suggested to cause ROP excluding low birth weight, young gestational age, and prolonged oxygen…

Some human and nature causes of the disease are caused by heredity, high cholesterol, hypertension (high blood pressure), atherosclerosis, and many other factors. The most common cause of heart disease is atherosclerosis. ("What Causes Coronary Heart Disease?") There are many symptoms of heart disease that could be mistaken for something else. Some symptoms include angina (chest pain), pain in neck or arm, palpitations, dizziness, or irregular heartbeat. Many of these symptoms are similar to a…

Cardiovascular Disease among the Population of the United States The World Heart Federation (2012) defines Cardiovascular Disease (CVD) as “a broad range of diseases that affect the heart and blood vessels” (n.p.). CVD is also known as Heart Disease (American Heart Association [AHA], 2015). According to Roger, Lloyd-Jones, Berry, et al. (2011) there are numerous types of cardiovascular diseases including: hypertension, coronary artery disease, congenital cardiovascular defects, stroke,…

Vascular anomalies are a serious medical condition that affect blood vessel formation in as many as 1 in 10 people (Richter and Suen 2015). Vascular anomalies can be divided into two broad categories: vascular tumors and vascular malformations (Richter and Suen 2015). Vascular tumors, also known as hemangiomas, are characterized by rapid growth with most undergoing involution once the patient has reached a certain age (Richter and Suen 2015). On the other hand, vascular malformations are…

detrimental and damaging to the heart muscle. If the plaque stuck to the artery walls were to rupture sudden cardiac death or a heart attack could result (WebMD: “Coronary Artery Disease”, 2016). Deposition of cholesterol rich deposits (plaques) in the inside lining of the coronary artery is the cause of coronary artery disease. The plaques are known as atheromatous plaques (atheromas) and result in thickening of the arterial wall and narrowing of the artery. The amount of blood that is able…
