Embryo 44 Day Old Circulatory System
Computer Generated Image from Micro-MRI, actual size of embryo = 13.0 mm - This image presents a left-frontal perspective of the embryo during its seventh week of development. This age is calculated from the day of fertilization. The concentration of this image is on the circulatory system. The heart is indicated as a red, bulk-like structure. Blood vessels can be seen extending towards the brain and to the rest of the embryo's body. The umbilical cord, as observed potruding from the body, serves as a means of exchanging nutrients and wastes between the embryo and mother.
