Deep vein

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…

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…

“Disseminated intravascular coagulation (DIC) is a life-threatening acquired pathologic process in which the clotting system is abnormally activated, resulting in widespread clot formation in the small vessels throughout the body. The pathophysiology is excess thrombin is generated, followed by deposition of fibrin strands in the body tissues.” (Ball, 2012) “The circulating fibrin fragments later begin to interfere with platelet aggregation and other aspects of the clotting mechanism, resulting…

What side of the heart is affected by congestive heart failure (right, left, or both)? At the point when the right half of the heart starts to work less effectively, it can't pump much blood into the vessels of the lungs. Would Fluid accumulate somewhere? If so, Where? Explain your answer. Yes, Congestive heart failure (CHF) happens when the heart's pumping activity turns out to be weak to the point that liquid starts to amass in the lungs and other body tissues. This li quid development is…

Jugular Veins The most accessible veins for examination are the internal and external jugular veins in the neck. Both veins drain bilaterally from the head and neck into the superior vena cava. The external jugular vein lies superficially and is just above the clavicle. The internal jugular vein lies deeper, along the carotid artery. It is best to examine the right internal jugular vein because it follows a more direct anatomical path to the right atrium of the heart. The column of blood inside…

constant (Merriam-Webster). Optic nerve: A part of the central nervous system, the optic nerve connects the eye to the brain, carrying electrical signals formed by the retina to be interpreted as images (Medicine Net). Central retinal vein: The central retinal vein is where blood circulating in the eye is returned to the heart to be cleaned. It forms the arterioles, branches of an…

1. Anatomy of the trachea and bronchi. The trachea (Fig.1) is a cartilaginous and membranous tube, extending from the lower part of the larynx, on a level with the sixth cervical vertebra, to the upper border of the fifth thoracic vertebra, where it divides into two main bronchi, one for each lung. The trachea is nearly but not quite cylindrical, being flattened posteriorly; it measures about 11 cm. in length; its diameter, from side to side, is from 2 to 2.5 cm., being always greater in…

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…

Impedance cardiography is a noninvasive technique for assessing stroke volume (and thus cardiac output) as well as pre-ejection period (systolic time intervals). To measure impedance, four dual-electrodes recorded basal transthoracic impedance (Z0) and the first derivative of that impedance, the change in impedance over time (dZ/dt). Biopac EL-500 dual-electrodes were placed on each side of the neck and on both sides of the abdomen (under the arms) at the level of the thoracic xiphisternal…

About blood Functions Blood is the biological fluid in our body that transports nutrients and oxygen to the cells, and also exports the metabolic waste product away from the cells. To ensure the supply of oxygen needed by our organs and tissues, there are four important steps: 1. The oxygen must be transferred from our lungs into the blood plasma 2. The oxygen is stored on the hemoglobin in the red cells 3. The oxygen is transported to our body cells via circulation. 4. The oxygen is released…
