    en.wikipedia.org/wiki/Ultrasonography_of_chronic...

    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/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]

    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 ...

    Lack of exercise is another common cause of water retention in the legs. Exercise helps the leg veins work against gravity to return blood to the heart. If blood travels too slowly and starts to pool in the leg veins, the pressure can force too much fluid out of the leg capillaries into the tissue spaces.

  7. Pulmonary edema - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_edema

    The term pulmonary edema literally means wet lungs. This term actually refers to a pathological condition of the lungs, frequently demonstrated by chest X-ray. Edema of the lungs should be thought of as the result of a disease such as congestive heart failure and not a disease in and of itself. In this case it would be a cardiac disease and not ...

    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 ...

  9. Physiology of decompression - Wikipedia

    en.wikipedia.org/wiki/Physiology_of_decompression

    Blood flow to the muscles is lower in cold water, but exercise keeps the muscle warm and flow elevated even when the skin is chilled. Blood flow to fat normally increases during exercise, but this is inhibited by immersion in cold water. Adaptation to cold reduces the extreme vasoconstriction which usually occurs with cold water immersion. [5]
