The metaphysis (pl.: metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. [1] It contains the growth plate , the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses.
[3] [4] Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate). During formation of the secondary ossification center, vascular canals (epiphysial canals) stemming from the perichondrium invade the epiphysis, supplying nutrients to the developing secondary ...
On a lateral chest radiograph, the aortopulmonary space is normally seen as the "aortopulmonary window". [1] The aortopulmonary space is a small space between the aortic arch and the pulmonary artery. It contains the ligamentum arteriosum, the recurrent laryngeal nerve, lymph nodes, and fatty tissue.

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).
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
An epiphyseal line is an epiphyseal plate that has become ossified. [1] The process of it forming from an epiphyseal plate is named epiphyseal closure . [ 2 ] In adult humans, it marks the point of fusion between the epiphysis and the metaphysis .
structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein; structures of the respiratory system, including the diaphragm, trachea, bronchi and lungs [1]
The aorta is the largest blood vessel in human body. The aorta is the root systemic artery (i.e., main artery). In humans, it receives blood directly from the left ventricle of the heart via the aortic valve. As the aorta branches and these arteries branch, in turn, they become successively smaller in diameter, down to the arterioles.
