Can anybody explain this?

Th arterial channels are vessels that comprise the initial functioning system of the embryo, and s basically the same for all vertebrates. The heart Pumps blood into the ventral aorta (truncus arteriosus) The ventral aorta then distributes blood into the aortic arches that run upward into the visceral arches Blood then enters the dorsal aorta from the aortic arches (embryos of jawed animals usually have six aortic arches.) Blood from the anterior aortic arches runs forward into the head to the internal carotid arteries Blood from the posterior aortic arches runs into the dorsal aorta and posteriorly, and may branch into the vitelline or umbilical artery or any of the other intersegmental arteries

    The right and left sides of the heart work together Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium. Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body
