Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm, after aneurysms of the abdominal aorta and iliac arteries. [2] [3] They may occur in pregnant women in the third trimester and rupture carries a maternal mortality of greater than 50% and a fetal mortality of 70 to 90%.
The right heart pumps deoxygenated blood to the lungs in the pulmonary circulation. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle. The right atrium is the upper ...
Isolated heart conduction system showing atrioventricular node. The AV node receives two inputs from the right atrium: posteriorly, via the crista terminalis, and anteriorly, via the interatrial septum. [8] Contraction of heart muscle cells requires depolarization and repolarization of their cell membranes. Movement of ions across cell ...
The myocytes of the heart (also called the myocardial fibers) are arranged in a general circumferential direction in the ventricles. In the left ventricle (LV), the fiber will change gradually in direction from a certain longitudinal-circumferential direction in the outer layer of the heart (epicardium) to another angulated direction almost orthogonal in the inner wall (endocardium), becoming ...
The human hepatic portal system delivers about three-fourths of the blood going to the liver.The final common pathway for transport of venous blood from spleen, pancreas, gallbladder and the abdominal portion of the gastrointestinal tract [2] (with the exception of the inferior part of the anal canal and sigmoid colon) is through the hepatic portal vein.
Oxygen-poor blood enters the right side of the heart through two large veins. Oxygen-rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. The capillaries are responsible for allowing the blood to receive oxygen through tiny air sacs in the lungs.
The unconditional love between a dog and its owner is always worth celebrating. In fact, many people (myself included) consider their dogs cherished family members, not just pets!
Splenic artery embolization is a minimally invasive procedure and, where successful, avoids splenectomy. If an individual's spleen is enlarged, as is frequent in mononucleosis , most physicians will advise against activities (such as contact sports ) where injury to the abdomen could be catastrophic.
