Aorta is one of the great arteries of the heart arising from the outflow tract of the left ventricle to supply oxygenated blood to the body (see figure 105b and figure 25).
Therefore, in order to maintain optimum cardiac performance and homeostasis, the heart has a network of blood vessels known as thecoronary vesselsthat take nutrient-rich blood to the heart tissue; as well as coronary veins that removes waste products from the cardiac myocytes. Their role is simil...

To examine this, we have utilized intracoronary injections of technetium-99m labeled albumin microspheres in 11 patients with valvular heart disease, and in 13 patients with chest pain syndrome or constrictive pericarditis. Eight patients with valvular heart disease had large, patchy, irregular ...
Small blood vessel diseases are often associated with impaired regulation of vascular tone. The current understanding of resistance arteries often focuses on how a level of vascular tone is achieved in the acute phase, while less emphasis is placed on me
Frozen sections of lung tissue were incubated with 125I-labeled α-ANP, and binding site density was assessed on IPA with an image analysis system. ANP relaxed IPA in pigs at all ages, but the effect was significantly greater at 6 and 17 d of age. Hypoxia in animals from 14 to 17 d...
There are many paths for a coronary tree to have, from the ostium to the ends. One individual route comprised a few segments partitioned by the bifurcation. Different vessel segments in different paths are labeled in the algorithm. Taking a coronary tree as an example, the ideal shape of ea...
this method on straightened coronary arteries. However, for both studies, the velocity profiles on patient-specific models might be significantly different. Itu et al. [19] developed a patient-specific coronary flow model coupled with a lumped heart model and a physiological model for the ...
Collectively, these data suggested that subepicardial ECs are the major source of intramyocardial coronary arteries in the ventricle wall, and that coronary arteries and veins have a common origin in the developing heart. Keywords: coronary artery; origin; development; subepicardial endothelial cell; ...
