Atherosclerosis[ a] is a pattern of the disease arteriosclerosis, [ 8] characterized by development of abnormalities called lesions in walls of arteries. This is a chronic inflammatory disease involving many different cell types, and driven by elevated levels of cholesterol in the blood. [ 9] These lesions may lead to narrowing of the arterial ...
Atheroma. Atherosclerotic plaque from a carotid endarterectomy specimen. This shows the division of the common into the internal and external carotid arteries. An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall. [ 1][ 2] The material consists of mostly macrophage cells, [ 3][ 4 ...
The aorta (/ eɪ ˈ ɔːr t ə / ay-OR-tə; pl.: aortas or aortae) is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac arteries).
Aortic unfolding is an abnormality visible on a chest X-ray, that shows widening of the mediastinum which may mimic the appearance of a thoracic aortic aneurysm. [ 1 ] With aging, the ascending portion of the thoracic aorta increases in length by approximately 12% per decade, whereas the diameter increases by just 3% per decade.
Google Translate is a web-based free-to-use translation service developed by Google in April 2006. [ 11] It translates multiple forms of texts and media such as words, phrases and webpages. Originally, Google Translate was released as a statistical machine translation (SMT) service. [ 11] The input text had to be translated into English first ...
The internal carotid artery supplies the brain. Plaque often builds up at that division and causes a narrowing (stenosis). Pieces of plaque can break off and block the small arteries above in the brain, which causes a stroke. Plaque can also build up at the origin of the carotid artery at the aorta. [citation needed]
Cardiology. Arteriolosclerosis is a form of cardiovascular disease involving hardening and loss of elasticity of arterioles or small arteries and is most often associated with hypertension and diabetes mellitus. [ 1] Types include hyaline arteriolosclerosis and hyperplastic arteriolosclerosis, [ 2] both involved with vessel wall thickening and ...
Capillaries join the arteries and veins. The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [ 1][ 2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia ...
