Arteries are smooth on the inside and tough on the outside. Their muscular wall helps the heart to pump blood. When the heart beats, the arteries expand and get filled with blood. When the heart relaxes, contraction of the arteries takes place, which exert enough force to push the blood ...

This causes a global increase of blood pressure and volume in systemic circuit: elastic arteries, muscular arteries and arterioles are mainly affected by this pressure and volume change. On the contrary, pressure in capillaries and venous blood flow remain constant regardless of systolic or diastolic...
After a thoracotomy in the left chest, the heart was exposed and ischemia was introduced by circling the LAD before the branch of second diagonal coronary arteries, and the suture was loosed to achieve reperfusion after 90 min ischemia. Cardiac patch (20 mm × 15 mm) was implanted ...
The heart ejects blood faster than it can run off through the arteries, so part of the ejected volume (67–80%) distends the elastic arteries and raises the pressure toward its maximum value, the systolic pressure, typically about 120 mmHg. When ejection slows, runoff of blood catches up ...

However, there are measuring positions where the amplitude of S2 can exceed that of S1. On the one hand, this is the case with measurements at the carotid arteries, as they are much closer to the aortic and pulmonary valves, where the S2 originates, than to the ventricle muscles and the...
Molecular distinction and angiogenic interaction between embryonic arteries and veins revealed by ephrin-B2 and its receptor Eph-B4. Cell. 1998;93:741–53. 20. Adams RH, Wilkinson GA, Weiss C, Diella F, Gale NW, Deutsch U, Risau W, Klein R. Roles of ephrinB ligands and EphB receptors ...
The aortic arches branch around the heart and allow for development of the branching system of arteries and veins necessary for normal blood flow in the adult animal. Aortic arches should not strangulate each other, nor should there be openings from one to another; defects of this type are a...
