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 ...
It is typically the most prominent superficial vein in the human body, and is visible when all other veins are hidden by fat or collapsed during a shock. It arises from the cephalic vein 2.5 cm (one inch) below the lateral epicondyle of the humerus, runs obliquely upward and medially, and empties into the basilic vein 2.5 cm (one inch) above ...
Deep and superficial veins of the arm and near thorax. The first entry of venous blood is from the convergence of two or more capillaries into a microscopic, post-capillary venule. [13] Post-capillary venules have a diameter of between 10 and 30 micrometres (μm), and are part of the microcirculation.
Lambert Sonna Momo developed in 2020 a new generation of scanner, the VenoScannerF, which scans finger veins in multiple views and extracts a key that is encrypted from end to end with a constantly changing random code. [19] It is developing a new floating-hand version available for the market in 2022. [20]
A fourfold increased incidence from the third to the eight decade in men and a preponderance among women of approximately 55-70%. [24] The average mean age of affected patients is 60 years. [16] Thrombophlebitis can develop along the arm, back, or neck veins, the leg is by far the most common site.
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. The capillaries may break, leaving small blood marks under the skin. The veins themselves can become swollen, painful and distorted – a condition known as varicose veins. [17]
The veins of the arm carry blood from the extremities of the limb, as well as drain the arm itself. The two main veins are the basilic and the cephalic veins. There is a connecting vein between the two, the median cubital vein, which passes through the cubital fossa and is clinically important for venepuncture (withdrawing blood).
A list of veins in the human body: Veins of the heart. Coronary sinus. Great cardiac vein; Oblique vein of left atrium; Middle cardiac vein; Small cardiac vein
