Vein

heart wall is composed of three layers of tissues: pericardium, myocardium and endocardium (Wilson, Waugh and Ross, 1996). Label structures of the heart for the diagram. Aorta is the major artery that carries oxygenated blood to the body. Pulmonary veins carry oxygenated blood from the lungs into the heart. Left atrium is one of the left upper chambers that takes oxygenated blood from the lungs and pumps it into the left ventricle which carries it to the body (MedicineNet, 2016). Left ventricle…

report a rare but completely avoidable complication i.e. loss of guide wire inside the vein during subclavian venous cannulation which was successfully removed by surgery. Keywords- Subclavian venous cannulation, Avoidable complication, Guide wire. Introduction- Although central venous catheterisation…

of arteries, arterioles, capillaries venous and veins. (Sherwood). Understanding this fundamental system is critical to help further understand even more complicated medical conditions such as Postural orthostatic tachycardia syndrome (POTS), inappropriate HR increase when standing (Freeman et al., 2011). In addition, the cardiovascular system also has other properties that helps ensure proper function. One of those properties involves how the veins dilate in response to metabolites, waste…

of an animal to the sun of their microcosm. Harvey outlines that the arteries and the veins contain the same blood in animals, and not blood from two separate sources as assumed by Galen. The document was written in 1628. It was written to Prince Charles, King of Great Britain, France, and Ireland. Harvey mentions Galen (Greek physician) and mentions that the same blood going into the heart, arteries and veins. At that time two separate systems were assumed to be involved in blood circulation.…

easily treatable if caught early. The definition of Pulmonary Embolism is a blockage or thrombi in one of the pulmonary arteries of your lungs (Pulmonary Embolism). Most of these thrombi originate in the veins in your lower extremities; though sometimes the thrombi can come from upper extremity veins, renal, pelvic, or right heart chambers, instead. Once in the pulmonary arteries, large thrombi sometimes lodge at the bifurcation of the main pulmonary artery and cause hemodynamic compromise…

Seeing how the Frog uses veins to carry its blood through the body, then that means it has a closed circulatory system, rather than an open one where the blood is just kinda floating about. Moving on the digestion of a Frog, they use their long tongues to latch onto various types…

Coronary arteries are one of the most important parts of the body because of many different factors. Heart muscle needs blood rich in oxygen to function and pump more blood throughout the circulatory system. If the blood does not carry enough oxygen, the veins will carry it away. Blood can only be delivered when the heart is relaxed; because once they contract they become narrow. These arteries are structured differently as opposed to many of the other arteries in the human body. The coronary…

congestion – these are characteristic of left-sided heart failure. In right-sided heart failure, hepatomegaly could occur due to the increased pressure within the hepatic vein; ascites could occur because of the pooling of blood in the inferior vena cava; and pitting edema could also occur due to increased fluid retention in the veins (from increased capillary…

Task 2 Part A Cebita Santhosh Q1. The three main types of blood vessels in the circulatory system are veins, arteries and capillaries. The veins carry deoxygenated blood from the capillaries back to the heart. The arteries carry blood away from the heart to your tissues. The capillaries are the smallest of the body's blood vessels, only one cell thick and are found in the muscles and lungs. Q2. Eating too much salt can raise your blood pressure because of the extra water stored in the…

Superior Vena Cava Syndrome The Superior Vena Cava (SVC) is the main blood vessel that transports de-oxygenated blood from the upper body to the heart. The SVC is a short vein located in the anterior right Superior Mediastinum, which is the area found in the mid-line of the Thorax (Drake et al. 2010). The vein is surrounded by many structures involved in the respiratory and circulatory system including the right Bronchus and the Mediastinal lymph nodes (Martini & Ivonne 2004). Figure 1 is a…
