superior vena cava is part of what system？
the human circulatory systemFunction. The superior vena cava is a vital structure in the human circulatory system that helps drain large amounts of deoxygenated blood from the head, eyes, neck, and upper limbs into the upper left chamber (atrium) of the heart.2021年4月19日
Correspondingly,Is the superior vena cava part of the venous system?
The superior vena cava is very important for the function of the cardiovascular system, since it largely contributes to the input of blood to the right atrium....Superior vena cava.

Additionally,What system is the inferior vena cava part of?
the venous systemThe IVC is a large blood vessel responsible for transporting deoxygenated blood from the lower extremities and abdomen back to the right atrium of the heart. It has the largest diameter of the venous system and is a thin-walled vessel.
Likewise,What is vena cava in circulatory system?
(VEE-nuh KAY-vuh) A large vein that carries blood to the heart from other areas of the body. The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest.
Regarding this,Does superior vena cava have valves?
There are no valves in either the SVC or the brachiocephalic veins.
The azygos vein is another vein that drains into the superior vena cava. This vein is unpaired. It runs along the right aspect of the thoracic vertebral column and enters into the thorax at the aortic hiatus of the diaphragm. The azygos vein forms from the joining of the right subcostal and ascending lumbar veins.
Your superior vena cava is next to the right side of your sternum and goes into your right atrium, where all the oxygen-poor blood goes. Your inferior vena cava is a little longer. It starts where the right and left common iliac veins come together in your belly area and goes up into the right atrium of your heart.
Structure. The IVC goes from the diaphragm into the right side of the heart, beneath the entrance of the superior vena cava. A few veins merge and drain into the IVC before it makes its way up to the heart: The left renal vein, the left adrenal vein, and left gonadal veins merge into the renal vein.
The superior and inferior vena cava and the pulmonary arteries have no valves because no back flow of blood is there in them as the blood is flowing from them into the atrium.
The inferior vena cava is a vein. It carries deoxygenated blood from the lower half of the body to the right atrium of the heart. The corresponding vein that carries deoxygenated blood from the upper half of the body is the superior vena cava.
The inferior vena cava (IVC) is the largest vein of the human body. It is located at the posterior abdominal wall on the right side of the aorta. The IVC's function is to carry the venous blood from the lower limbs and abdominopelvic region to the heart.
deoxygenated bloodThe superior vena cava collects deoxygenated blood from the venous system associated with the upper limbs, head, neck, and thorax. The superior vena cava terminates in the right atrium providing deoxygenated blood to the pulmonary circulation.
On each side, the subclavian vein, the principal vein of the upper extremity, joins with the internal jugular, the principal vein of the head and neck, here, behind the medial end of the clavicle, forming the brachiocephalic vein. The two brachiocephalic veins enter the thorax and unite, forming the superior vena cava.
