Blood air to all of the cells of the body, and venous blood carries carbon dioxide, a waste product of metabolism by cells, to the lungs to be exhaled. However, one exception includes pulmonary arteries, which contain the most deoxygenated blood in the body, while the pulmonary veins contain oxygenated blood. Additional return flow may be generated by the movement of skeletal muscles, which can compress veins and push blood through the valves in veins toward the right atrium. The blood circulation was famously described by William Harvey in 1628. In vertebrates, the various cells of blood are made in the
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
