The anatomy of arteries can be separated into gross anatomy, at the macroscopic level, and microanatomy, which must be studied with a microscope.The arterial system of the human body is divided into systemic arteries, carrying blood from the heart to the whole body, and pulmonary arteries, carrying deoxygenated blood from the heart to the lungs.

The external carotid artery; The triangles of the neck; The internal carotid artery; The arteries of the brain; The arteries of the upper extremity The subclavian artery; The axilla. The axillary artery; The brachial artery; The radial artery; The ulnar artery; The arteries of the ...
In humans, arteries do not have valves except for the two 'arteries' that originate from the heart's ventricles. [ 9 ] Early estimates by Danish physiologist August Krogh suggested that the total length of capillaries in human muscles could reach approximately 100,000 kilometres (62,000 mi) (assuming a high muscle mass human body, like that of ...
The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart.
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. Starting from the aorta: the following are the parts
When two arteries or their branches join, the area of the myocardium receives dual blood supply. These junctions are called anastomoses. If one coronary artery is obstructed by an atheroma, the second artery is still able to supply oxygenated blood to the myocardium. However, this can only occur if the atheroma progresses slowly, giving the ...
The great arteries originate from the aortic arches during embryonic development.The aortic arches start as five pairs of symmetrical vessels connecting the heart with the dorsal aorta but then undergo a significant remodelling, [1] in which some of these vessels regress (aortic arches 1 and 2), the 3rd pair of arches contribute to form the common carotids, the right 4th will contribute to the ...
Angiology (from Greek ἀγγεῖον, angeīon, "vessel"; and -λογία, -logia) is the medical specialty dedicated to studying the circulatory system and of the lymphatic system, i.e., arteries, veins and lymphatic vessels. [1] In the UK, this field is more often termed angiology, and in the United States the term vascular medicine is more ...
