  2. Chronic venous insufficiency - Wikipedia

    en.wikipedia.org/wiki/Chronic_venous_insufficiency

    Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]

    A gel is used with the probe to make a good acoustic impedance contact. The training and expertise of the examiner is important because of the many technical complications that can present. Venous anatomy, for example, is not constant; for example, a patient's vein layout of the right limb is not identical to that of the left limb. [citation ...

    en.wikipedia.org/wiki/Peripheral_vascular_system

    The peripheral vascular system is the part of the circulatory system that consists of the veins and arteries not in the chest or abdomen (i.e. in the arms, hands, legs and feet). [1] [2] The peripheral arteries supply oxygenated blood to the body, and the peripheral veins lead deoxygenated blood from the capillaries in the extremities back to ...

    Humans inhabit hot climates, both dry and humid, and have done so for millions of years. Selective use of clothing and technological inventions such as air conditioning allows humans to live in hot climates. One example is the Chaamba, who live in the Sahara Desert. They wear clothing that traps air in between skin and the clothes, preventing ...

    Phlebitis is the inflammation of a vein. It is usually accompanied by a blood clot when it is known as thrombophlebitis. When the affected vein is a superficial vein in the leg, it is known as superficial thrombophlebitis, and unlike deep vein thrombosis there is little risk of the clot breaking off as an embolus. [10]

  7. Pulmonary circulation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_circulation

    The pulmonary arteries carry deoxygenated blood to the lungs, where carbon dioxide is released and oxygen is picked up during respiration. [3] Arteries are further divided into very fine capillaries which are extremely thin-walled. [4] The pulmonary veins return oxygenated blood to the left atrium of the heart. [3]

    Bubbles which are carried back to the heart in the veins will normally pass into the right side of the heart, and from there they will normally enter the pulmonary circulation and eventually pass through or be trapped in the capillaries of the lungs, which are around the alveoli and very near to the respiratory gas, where the gas will diffuse ...
