Pericardial diaphragmatic artery

The pericardial diaphragmatic artery (a. pericardiacophrenica) is an artery that supplies blood to the abdominal cavity and diaphragm. It is a branch of the abdominal aorta and passes through the chest at the level of the fifth thoracic vertebra.

The pericardiophrenic artery begins from the abdominal aorta at the level of the tenth thoracic vertebra and passes through the diaphragm into the abdominal cavity. It is divided into two branches:

– Pericardial branch (ramus pericardialis) - passes through the pericardium and supplies the heart and pericardium.
– Diaphragmatic branch (ramus phrenicus) - passes through the diaphragm and supplies the diaphragm, liver, stomach and intestines.

Functions of the pericardial phrenic artery:

1. Nutrition of the heart and pericardium.
2. Providing oxygen and nutrients to the abdominal organs.
3. Participation in the regulation of blood pressure.
4. Participation in the metabolism of hormones and other substances.
5. Immune system support.
6. Participation in the body's defense mechanisms.

Dysfunction of the pericardial phrenic artery can lead to various diseases, such as myocardial infarction, coronary heart disease, diseases of the liver, stomach and intestines, as well as decreased immunity and protection of the body.

The pericardiophrenic artery is an artery located between the diaphragm and the pericardium. It is a branch of the aorta and is an important part of the abdominal circulation. As blood passes through this artery, it is delivered to the diaphragm and peritoneal area.

Origin of the arteriode: This artery originates from the thoracic aorta below the origin of the brachiocephalic vein. Partially it runs parallel to the pleura and the right edge of the diaphragm, then crosses the esophagus and descends to the bifurcation of the trachea. Near the latter, it continues its direction, parallel to
