It serves two main functions: Separates the thoracic cavity from the abdominal cavity (the word diaphragm is derived from the Greek diphragma, meaning partition). The main branches of the left portal vein originate from the umbilical portion, and supply liver segments 2, 3 and 4 5. These branches extend the reach of the aorta to muscles, nerves and organs throughout your body. The abdominal aorta begins at T12 and ends It arises from the abdominal aorta, and supplies many of the gastrointestinal viscera. Abdominal branches include the celiac trunk, superior mesenteric artery, middle suprarenal arteries, renal arteries, inferior mesenteric artery, inferior phrenic artery and lumbar arteries. It travels inferiorly into the superior mediastinum, bifurcating at the level of the sternal angle (forming the right and left main bronchi).As it descends, the trachea is The feared complication is rupture which is a surgical emergency due to its high mortality. Two circuits, the pulmonary and the systemic, consist of arterial, capillary, and venous components. Each portal venule courses alongside a hepatic arteriole and the two vessels form the vascular components of the portal triad. detect atherosclerotic (plaque) disease in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke. It is a closed tubular system in which the blood is propelled by a muscular heart. Roots: L1 (with contributions from T12). The portal vein ramifies further, forming smaller venous branches and ultimately portal venules. Structure. Key words: aneurisms, abdominal aorta. The terminal branches of the abdominal aorta, the left and right common iliac arteries, arise from the bifurcation in front of the body of L4 vertebra about 1.25 cm to the left of the median plane. The portal vein ramifies further, forming smaller venous branches and ultimately portal venules. Chaikof et al. Right coronary artery (Arteria coronaria dextra) The right coronary artery (RCA) is one of two main coronary vessels that supply the myocardium (the other being the left coronary artery).It originates from the right aortic sinus of the ascending aorta and runs in the right part of atrioventricular groove (coronary sulcus) wrapping around the right side of the heart.

Branches. Imaging has a key role in active surveillance. The descending thoracic aorta is part of the aorta, which has different parts named according to their structure or location.The descending thoracic aorta is a continuation of the descending aorta and becomes the abdominal aorta when it passes through the diaphragm.The initial part of the aorta, the ascending aorta, rises out of the left ventricle, from which it is separated by the The terminal branches of the abdominal aorta, the left and right common iliac arteries, arise from the bifurcation in front of the body of L4 vertebra about 1.25 cm to the left of the median plane. The vagus nerve follows a long course to supply the thoracic and abdominal organs up to the level of the distal transverse colon, synapsing in ganglia within the organ walls. Veins of the abdomen all converge to one major vessel the inferior vena cava. The abdominal aorta (plural: aortas or aortae 4) is the main blood vessel in the abdominal cavity that transmits oxygenated blood from the thoracic cavity to the organs within the abdomen and to the lower limbs.
