Vein veins), not their oxygen content. In addition, deoxygenated blood that is carried from the tissues back to the heart for reoxygenation in the systemic circulation still carries some oxygen, though it is considerably less than that carried by the systemic arteries or pulmonary veins. Although most veins take blood back to the heart, there is an exception. Portal veins carry blood between capillary beds. For example, the hepatic portal vein takes blood from the capillary beds in the digestive tract and transports it to the capillary beds in the liver. The blood is then drained in the gastrointestinal tract and
Congenital diaphragmatic hernia baby will usually be immediately placed on a ventilator. Extracorporeal membrane oxygenation (ECMO) has been used as part of the treatment strategy at some hospitals. ECMO acts as a baby heart-lung bypass (though it can be used for older children as well). A venous cannula is inserted into the jugular vein or the common femoral vein(ECMO is divided into two types; (arteriovenous AV and venovenous VV), allowing the blood to exit the body and begin its trek through the ECMO circuit, it is then scrubbed, oxygenated, and passes through a filter before being returned to the body via a second
