Anatomical terminology. The anterior cardinal veins (precardinal veins) contribute to the formation of the internal jugular veins and together with the common cardinal vein form the superior vena cava. In an anastomosis by anterior cardinal veins, the left brachiocephalic vein is produced..
Also to know is, what is Vitelline vein?
The vitelline veins are developmental vessels passing between the yolk sac and the sinus venosus of the heart. There are two key vessels, the right and left vitelline veins, which pass cephalically throught the septum transversum and in close proximity to the duodenum.
Additionally, what drains into the left brachiocephalic vein? Left and right inferior thyroid veins: drain into the superior aspect of their corresponding veins near the confluence. Left and right vertebral vein. Left superior intercostal vein: drains into the left brachiocephalic vein.
Moreover, where do the Subcardinal veins empty?
The right subcardinal vein develops to drain most of the upper, the right supracardinal vein most of the lower part of the abdomen. Majority of the azygos system develops from the cranial part of the supracardinal veins.
What is a sinus venosus?
The sinus venosus is a large quadrangular cavity which precedes the atrium on the venous side of the chordate heart. In mammals, it exists distinctly only in the embryonic heart (where it is found between the two venae cavae); however, the sinus venosus persists in the adult.

Where does the portal vein drain into?
The superior and inferior mesenteric veins join the splenic vein behind the pancreas to form the portal vein which carries blood to the liver, which in turn is drained by the hepatic veins which pass into the IVC.Where does the umbilical vein drain?
The umbilical vein enters at the umbilicus and reaches the anteroinferior portion of the liver to finally drain in the portal sinus 3. The ductus venosus connects the portal sinus with the confluence of the hepatic veins into the inferior vena cava.Where does the Vitelline vein receive blood from?
The vitelline veins drain the gut tube, the umbilical veins bring oxygenated blood from the placenta, and the cardinal veins drain the head and body wall (Fig. 6.12). The proximal portions of both umbilical veins disappear, as does the distal part of the right umbilical vein.Why does the umbilical artery carry deoxygenated blood?
The fetal-placental circulation allows the umbilical arteries to carry deoxygenated and nutrient-depleted fetal blood from the fetus to the villous core fetal vessels. After the exchange of oxygen and nutrients, the umbilical vein carries fresh oxygenated and nutrient-rich blood circulating. J. Leandro, (2001).What is fetal circulation?
In animals that give live birth, the fetal circulation is the circulatory system of a fetus. The term usually encompasses the entire fetoplacental circulation, which includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.What is Allantois human?
The allantois (plural allantoides or allantoises) is a hollow sac-like structure filled with clear fluid that forms part of a developing amniote's conceptus (which consists of all embryonic and extra-embryonic tissues). It helps the embryo exchange gases and handle liquid waste.Where is the coronary sinus located?
The coronary sinus is a collection of smaller veins that merge together to form the sinus (or large vessel), which is located along the heart's posterior (rear) surface between the left ventricle and left atrium.What is the fate of the ductus venosus after birth?
After birth, the ductus venosus closes due to changes in intracardiac pressures and a decrease in endogenous prostaglandins. Failure of the ductus venosus to close may result in galactosemia, hypoxemia, encephalopathy with hyperammonia, and hepatic dysfunction.Where is the left brachiocephalic vein located?
The brachiocephalic vein, also known as an innominate vein, is a vein that returns oxygen-depleted blood from the upper limbs, neck, and head to the heart. There is a brachiocephalic vein on the left side of the neck and one on the right.Where is the common iliac vein located?
The left and right common iliac veins come together in the abdomen at the level of the fifth lumbar vertebra, forming the inferior vena cava. They drain blood from the pelvis and lower limbs. Both common iliac veins are accompanied along their course by common iliac arteries.What is the longest vein in the body?
great saphenous vein
What is the function of the brachiocephalic vein?
The brachiocephalic vein, also known as an innominate vein, is a vein that returns oxygen-depleted blood from the upper limbs, neck, and head to the heart through its continuation, the superior vena cava.Where is the innominate vein located?
The brachiocephalic veins also referred to as the innominate veins, are large venous structures located within the thorax and originate from the union of the subclavian vein with the internal jugular vein. The left and right brachiocephalic vein join to form the superior vena cava on the right side of the upper chest.Why is there only one Brachiocephalic artery?
Whereas in the left side, the left common carotid artery and the left subclavian artery arises directly from the arch of aorta. So, there is no left brachiocephalic artery. And we are left with only one brachiocephalic artery. The axillary artery in each arm then gives rise to brachial artery.What is a Brachiocephalic?
The brachiocephalic artery (or brachiocephalic trunk or innominate artery) is an artery of the mediastinum that supplies blood to the right arm and the head and neck.Why is the left brachiocephalic vein longer?
The left brachiocephalic vein is usually longer than the right because at one point it travels across the body from left to right. Both veins meet at one point to form the superior vena cava that leads to the right atrium. Because the left vein must go towards the right atrium, it crosses across the body.What vein runs parallel to the right carotid artery?
Both branches of the internal jugular vein had the same thickness and poured into the right subclavian vein. The anterior branch was parallel to the carotid artery and received the common facial vein, the superior and inferior thyroid veins, and the transverse cervical vein.Do birds have a sinus venosus?
The sinus venosus-derived myocardium becomes electrically synchronized with the atria, and the sinuatrial delay seen in ectothermic vertebrates is lost. Birds probably resemble mammals rather than ectotherms. (4) It is not known why the sinus venosus atrializes in mammals.What is sinus venosus and Conus arteriosus?
The sinus venosus is the most caudal portion of the heart and collects the venous blood; the atrium is a large sac with a relatively thin muscular wall; the ventricle is a muscular chamber responsible for developing the pressure needed to propel the blood into the circulation and shows considerable variability in shape
