The pericardiacophrenic arteries travel through the thoracic cavity. They course through the fibrous pericardium. [2] The pericardiacophrenic artery accompanies the phrenic nerve between the pleura and pericardium, to the diaphragm. [3] This is where both the artery and the phrenic nerve are distributed.
The pericardium (pl.: pericardia), also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. [1] It has two layers, an outer layer made of strong inelastic connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium).
Pericardiacophrenic veins are the venae comitantes of the pericardiacophrenic arteries. Pericardiacophrenic vessels accompany the phrenic nerve in the middle mediastinum of the thorax. The vein drains into the internal thoracic vein, or brachiocephalic vein. [1
English: Microscopic anatomy of an artery. The outermost layer is known as tunica adventitia, and is composed of connective tissue made up of collagen fibers. Inside this layer is the tunica media, or media, which is made up of smooth muscle cells and elastic tissue (also called connective tissue proper).

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 ...
In approximately 33% of individuals, the left coronary artery gives rise to the posterior descending artery [4] which perfuses the posterior and inferior walls of the left ventricle. Sometimes a third branch is formed at the fork between left anterior descending and left circumflex arteries, known as a ramus or intermediate artery. [5]
