Over time, factors such as elevated arterial blood sugar (particularly as seen in diabetes mellitus), lipoprotein, cholesterol, high blood pressure, stress and smoking, are all implicated in damaging both the endothelium and walls of the arteries, resulting in atherosclerosis. Atherosclerosis is a disease marked by the hardening of arteries.
Add label for gastroduodenal artery. Better draw for epigastric arteries. Added temporal arteries (not labeled). 11:01, 21 June 2020: 550 × 830 (1.19 MB) Jmarchn: Corrections to celiac trunk, iliac vessels (adding posterior branchs to internal iliac vessels)and thoracic arteries. Add left branch of the portal vein, added shoulder arteries: 21: ...
They are roughly grouped as "arterial" and "venous", determined by whether the blood in it is flowing away from (arterial) or toward (venous) the heart. The term "arterial blood" is nevertheless used to indicate blood high in oxygen, although the pulmonary artery carries "venous blood" and blood flowing in the pulmonary vein is rich in oxygen ...
The presence or absence of atherosclerosis or atheroma within the walls of the arteries cannot be clearly determined. Coronary angiography can visualize coronary artery stenosis, or narrowing of the blood vessel. The degree of stenosis can be determined by comparing the width of the lumen of narrowed segments of blood vessel with wider segments ...
In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. This article regards the human arterial tree.
Add left branch of the portal vein, added shoulder arteries: 06:08, 2 June 2020: 550 × 830 (880 KB) Jmarchn: Added enterohepatic circulation and coronary vessels: 21:37, 25 May 2020: 550 × 830 (765 KB) Jmarchn: Draw in layers to made easy the modifications. Correction of the position of many of the arteries, veins and heart.
The right marginal arteries perfuse the right ventricle and the posterior descending artery perfuses the left ventricular posterior and inferior walls. There is also the conus artery , which is only present in about 45 percent of the human population, and which provides collateral blood flow to the heart when the left anterior descending artery ...
The arterial system itself arises from aortic arches 3, 4 and 6 (aortic arch 5 completely regresses). The dorsal aortae, present on the dorsal side of the embryo, are initially present on both sides of the embryo. They later fuse to form the basis for the aorta itself. Approximately thirty smaller arteries branch from this at the back and sides.
