spread. Amongst these convulsions there arose a very widely spreading common problem of Varicose Veins. In some cases these veins do not cause any serious problems but in cases of serious cosmetic issues and dermatitis, varicose veins treatment becomes a necessity. What are VARICOSE VEINS? These are a type of transformed veins underneath the surface of skin. Varicose veins are twisted, enlarged veins near the surface of skin most commonly in the legs and ankles. One of the mainsprings of this…

Spider veins or Telangiectasia as they are better medically known, are small permanently dilated capilliaries or venules and are often found in the face, legs and ankles. The presence of these veins can indicate a deeper circulatory problem but in most cases will be superficial and therefore harmless. (Werner, 2016) Spider veins are very similar to Varicose veins although much smaller and a lot closer to the skin. Veins carry deoxygenated blood through our body and back to our heart. In the…

The coronary veins are responsible for collecting the oxygen-depleted blood which is a result of the exchanging of oxygen-rich blood within the capillary beds of the myocardium. The three major coronary arteries associated with coronary circulation are the small cardiac vein, the middle cardiac vein, and the great cardiac vein. These three coronary veins ultimately join to form the coronary sinus which is essentially an enlarged vessel…

The spleen can be found in the left upper quadrant of the abdomen, lying posteriorly to the stomach and underneath the diaphragm. The spleen can be found enclosed in a capsule of dense irregular connective tissue (Krause, 2008). Prone to infections and other conditions, the spleen can easily become enlarged because it is highly vascularized. Malignancies, parasites, liver diseases and other conditions passed in the blood and immune system can cause the spleen to be infected. In addition to the…

and spider veins affect almost half of the adults in the United States. Spider veins are unsightly with purple and red veins, and varicose veins are also unsightly, but also feel heavy when they are swollen and cause pain and fatigue. There are two main treatments for these conditions including sclerotherapy and laser treatment. Our trained technicians will examine your veins and recommend the best treatment for you. Varicose veins are usually caused by damaged or weak valves in the veins.…

Venous return is the flow of blood back to the heart. This process is achieved by five mechanisms. The Pressure Gradient, now this mechanisms work via the heart generating pressure even though the pressure is weaker in the veins than in the arteries it is still the most important force in the venous flow. Gravity, but only when you are sitting or standing anywhere above the heart simple gravity is at work in returning blood back to the heart, not to say that very thing isn’t still working…

pancreas, and the small and large intestine. All the veins from the portal venous system will come together to form the portal vein which then carries substrate-rich venous blood to the liver. The blood in the liver will then be drained by the hepatic veins. Portal hypertension is associated with chronic liver diseases and is a result of an increase in blood pressure in the portal vein. There is a pressure gradient between the portal vein and the hepatic vein which is called the hepatic venous…

pulse flow (it can contract and stretch) The outer layer (tunica adventitia) contains collagen prevents the artery rupturing due to the high pressure blood flow Veins Veins carry blood under low pressure (<10 mm Hg) They have a very wide lumen (keeps pressure low and allows greater flow of blood) The walls of tissue surrounding the vein are thin (blood is not travelling in rhythmic pulses) They have valves to prevent blood pooling at extremities (arteries do not have valves) Capillaries…

cellular waste products and permits blood to circulate and form cells in the body to nourish it with every heartbeat throughout the body.However, the Cardiovascular system is composed of the following organs, heart and blood vessels, including arteries, veins, and capillaries. One of the major structures of this system is the heart which functions to propel blood throughout the body, supplying oxygen and nutrients to the tissues. For example, the right side of the heart pumps blood through the…

The initial electrical impulse that begins the process of a heartbeat is generated by a group of cells located in the upper chamber of the heart. This special pathway is as follow: the sinoatrial node, atrioventricular node, his-purkinje network. The impulse starts in a small bundle of specialized cell which is known as the sinoatrial node located in the right atrium. The sinoatrial node sets the rate and rhythm of the heartbeat. The atrioventricular node slows the electrical signal before…
