Hepatic portal vein

pulmonary edema are shortness of breath, difficulty breathing, and chest pain. Edema in the legs can happen from long periods of time sitting such as a long flight. Persistent leg pain and swelling could be signs of a potential blood clot in the veins called deep vein thrombosis, or DVT for short. Edema could also be the result of eating too much salty food, premenstrual…

Arterial color duplex study was performed for bilateral lower limbs which revealed mild atherosclerosis of the arteries without narrowing or blockage, no aneurysms in the popliteal arteries and confirmed the presence of a right DPA aneurysm with a small mural thrombus. Right foot toes pressure measurement showed normal readings (Fig.2). Surgical exploration was carried out under ankle block. A longitudinal skin incision was made directly over the aneurysm. Sharp dissection through fascia…

Syncope is sufficient blood flow to the brain which causes loss of consciousness which also causes fainting. It often happens in patients with hypotension which comes from the heart not pumping enough oxygen. Some of the causes of syncope is dehydration, heavy sweating, pooling of blood in the legs, exhaustion, disorder occur with exercise and with palpations or irregularities of the heart also with family history of recurrent syncope or sudden death. Risk factors are usually being…

is largely contributed to the feeble veins that elderly have. Vein quality can be contributed to many different patient characteristics as well. In many hospitals, the patients who have an IV inserted in their arm or hand are only getting their IV site assessed and flushed once per shift. There was no correlation in Salgueiro-Oliveira & Parreira’s study of the duration of the indwelling IV catheter and solely inflammation of the vein due to medications and vein integrity, although the chance of…

The conventional on pump CABG employed CPB to extracorporeal oxygenate the venous blood through the machine and then pump the blood back to the patient while the surgeon perform anastomosis between a graft and a coronary artery. During the surgical procedure, a cross-clamping was applied on the aortic artery to provide myocardial protection, and the heart was induced to cardioplegia with drugs, so the surgeon can perform anastomosis on a motionless field, thus guaranteeing the quality of the…

Pulmonary Atresia is a very serious type of congenital heart condition. There are actually two main characteristics: 1) The pulmonary valve, which allows the blood to flow from the heart to the lungs, is completely blocked. 2) There is a large hole- ventricular septal defect- between the two main pumping chambers in the heart. You see, in a normal heart, the blood passes the pulmonary artery to the lungs to collect oxygen. With people who have pulmonary atresia, the blood can’t pass through…

Cardiovascular System The cardiovascular system consists of the blood vessels and the heart. They function is to circulate the blood around the body to all the muscles. The red blood cells carry oxygen to all the muscles through the vein (carries blood to the heart). The veins have thin walls and contain blood under the low pressure. The arteries (carries blood away from the heart) have thick muscular walls and small passage ways. They contain blood under high pressure. The last blood vessels is…

lines the arteries and veins. The tunica intima, is a single layer of squamous epithelial cells that lines the inner surface of the entire cardiovascular system. In many veins, the tunica intima is equipped with pockets that act as one-way valves. These valves prevent the back flow of blood and allow the veins to act as supplemental pumps that help to keep the blood following in one direction, back toward the heart. The activity of the skeletal muscle that surround the veins will create the…

are called veins. They constitute a system called venous system. Venous system of frog can be studied under too heading A) Systemic Venous System This system includes the three large veins, which receives the deoxygenated blood from all the parts of the body and collect to the sinus venous. The three veins are- Right Precaval, Left precaval and Post cavals 1. Right and Left Precaval Vein: Each precaval is formed by the union of 3 veins External jugular vein - it is formed by the two veins. a.…

homeostasis; and transport gases, waste, and hormones. The different types of blood vessels are: arteries, capillaries, and veins. The vessels that carry blood towards the heart are veins and the vessels that carry blood away from the heart are arteries. Gas exchange occurs in the capillaries. 2. Describe the layers of blood vessels. Describe the differences between arteries and veins. The layers of blood vessels are: a hollow interior (lumen), contains an outer…
