    According to Chisholm-Burns et al., deep vein thrombosis (DVT) is the result of venous thromboembolism (VTE) and can lead to pulmonary embolism, (PE). Deep vein thrombosis (DVT) is the result of a clot (blood that aggregates together) situated in a deep vein of the lower extremities (National Library of Medicine -PubMed Health, n.d.). Pathophysiology of DVT “Deep venous thrombosis usually arises in the lower extremities. Most DVT’s forms in the calf veins, particularly in the Soleus sinusoids and

    The small saphenous vein (SSV) is a superficial vein in the leg. It originates from the lateral side of the dorsal venous arch passes behind the distal end of the fibula and up the back of the leg to penetrate deep fascia and join the popliteal vein posterior to the knee [1]. This vein is considered the second largest blood vessel in the leg. Like most of the superficial leg veins, this vein features smooth muscle cells in its adventitia and the inner media [2]. Also SSV is in danger of becoming

    Varicose Veins Overview- A varicose vein (or varicose veins) is the abnormal dilation of the veins that appear swollen and that sometimes, when the varicose vein involves a superficial vein, can be observed through the skin. In our body the arteries carry oxygenated blood to the rest of the body from the heart, the veins, however, return the oxygen-poor blood to the heart because it is pushed towards the lungs and oxygenated. The arteries, which push oxygenated blood, they have a very effective

  • The Cardiovascular System: The Circulatory System

    1054 Words  | 5 Pages

    CIRCULATORY SYSTEM 1. INTRODUCTION The circulatory system is also known as the cardiovascular system. This system is a double circulatory closed system which transports blood via arteries, veins and capillaries to the lungs through the pulmonary circulation and to the rest of the body tissues in the systemic circulation. Since the blood travels to varying distances around the body, the blood vessels have to be adapted to overcome different pressures. The pressure changes in the four chambers on the

    Capillaries and Veins: Function of the Heart: The heart is a muscular organ in humans which pumps blood through the bold vessels of the circulatory system. Blood provides the body with oxygen and nutrients and also assists in the removal of waste. The heart is a pump that drives the whole circulatory system. It receives and propels blood, rhythmically contracting, forcing the blood through a system of vessels. The hearts action is controlled by the autonomic nervous system.

    low, although blood here is at a slightly higher pressure than the blood in the pulmonary vein, and this is reflected as the walls of the artery are significantly thinner than the walls of a corresponding artery, for example, the aorta. The walls of the pulmonary artery contain a large amount of elastic fibres in order to maintain the shape of the artery. The lumen of the artery is smaller than that of the vein which has a large lumen. This relates to the pressure difference between the two blood vessels

  • Function Of The Heart Essay

    Explain the function of the heart and the structure of arteries, veins and capillaries. Referring to Louise Tucker 5th edition, the heart is an organ that pumps blood through the body via the circulatory system, supplying nutrients and oxygen to the tissues and removing carbon dioxide and other waste products. According to Louise Tucker arteries are thick walled, hollow tubes with a fibrous outer covering, a middle layer of muscle and elastic tissue. The functions of arteries are: • Carry oxygenated

    blood from flowing back in the incorrect way (Ballard, 7). As the right side of the heart pumps oxygen-deprived blood along the pulmonary arteries to the lungs, blood loses carbon dioxide and collects oxygen in the lungs (Rogers, 66). "The pulmonary veins open into the left atrium of the heart," recalls Rogers (66). This is pulmonary circulation. When the left side of the heart pumps blood along the aorta and around every part of the body, it takes oxygen to the tissues where it is needed and collects

The cardiovascular system, also named as the circulatory system, is the system that transports blood all over the human body. It is composed of the heart, arteries, veins, and capillaries. It delivers oxygenated blood from the lungs and heart through the entire body by the arteries. Blood drives through the capillaries - vessels located between the veins and arteries. When

    Unsightly spider and reticular veins are caused because of increased pressure. They are usually hereditary, but there are other causes. Reticular veins appear slightly blue or purple under the skin and may exist independently, but can also be a warning signal that spider veins may appear. Spider veins are also called thread veins and are very common. They appear in superficial blood vessels like varicose veins, but spider veins are closer to the surface of the skin. They are often found behind

    Allowing a full intake and out-take of blood. What is special about the pulmonary artery and vein? Why? The veins around the body generally transport deoxygenated blood from places in the body back to the heart, however, the pulmonary vein is one of the few veins that hold and transport oxygenated blood through the body. However, the pulmonary artery carries deoxygenated blood, and the pulmonary vein transports oxygenated blood. Labelled diagram of the
