Formation of blood vesselsCardiovascular system is the first organ system that functions in the development of human beingsThe formation of the embryo part extraIn vertebrates that rich yolk ( chicken ) , a vein vitellin (omfalomesenterika ) formed from a collection of cells of the mesoderm splanknik to the islands of blood in the yolk sac
The embryo age 24 hours : marked thickening of the mesoderm splanknik opaka in the area of the islands of bloodfirasti-biologi.blogspot.com, J.FRANCE,2005
13Age 33-38 hours the islands blood anastomoses each other forming a vein vitelina
The age 48 hoursA vein vitelina omfalomesentrika combine to form a vein that rises in the newly formed in the heart
The mechanism the formation of the circulatory systemThe formation of medan kardiogenik System of veins humans appears in the middle of the third week , when mudigah no longer able to meet the needs only through the diffusion of nutrition .
