Journal of Phlebology and Lymphology (1983-8905) is a peer reviewed open access journal. This scientific journal aims to provide the most complete and reliable source of information on the current developments in the field of Phlebology and Lymphology. The emphasis will be on publishing quality papers rapidly and making them available to researchers worldwide at no cost.

Journal of Phlebology and Lymphology is devoted entirely to function, mechanism, pathology of Lymphatic system and venous diseases. The journal keeps interventionalists, phlebologists, wound care specialists that treat acute, chronic and emergency wounds, and allied health professionals up-to-date by providing novel and authoritative information about experimental, clinical and basic science, medical research and clinical studies on a variety of Lymphatic system and diseases of the veins.

Contributors are welcome to publish high quality clinical, and laboratory research papers, case series, reviews, guidelines, techniques, and practice manuscripts related to all aspects of venous, lymphatic diseases, and wound care.Venous blood is deoxygenated blood which travels from the peripheral blood vessels, through the venous system into the right atrium of the heart. Deoxygenated blood is then pumped by the right ventricle to the lungs via the pulmonary artery which is divided in two branches, left and right to the left and right lungs respectively. Blood is oxygenated in the lungs and returns to the left atrium through the pulmonary veins.

Venous blood is typically colder than arterial blood,and has a lower oxygen content and pH. It also has lower concentrations of glucose and other nutrients, and has higher concentrations of urea and other waste products. The difference in the oxygen content of arterial blood and venous blood is known as the arteriovenous oxygen difference.

Most medical laboratory tests are conducted on venous blood, with the exception of arterial blood gas tests. Venous blood is obtained for lab work by venipuncture (also called phlebotomy), or by finger prick for small quantities.

The color of human blood ranges from bright red when oxygenated to a darker red when deoxygenated.It owes its color to hemoglobin, to which oxygen binds. Deoxygenated blood is darker due to the difference in shape of the red blood cell when hemoglobin binds to it (oxygenated) versus does not bind to it (deoxygenated). Human blood is never blue.

The blue appearance of surface veins is caused mostly by the scattering of blue light away from the outside of venous tissue if the vein is at 0.5 mm deep or more. Veins and arteries appear similar when skin is removed and are seen directly.
