Two large veins that carry blood from the body to the right atrium.
The principle vein returning blood to the right atrium.
Either of two large veins returning deoxygenated blood from the peripheral circulation to the right atrium of the heart.
One of the two largest veins in the body. The superior vena cava starts at the top of the chest and carries blood from the head, neck, arms, and chest to the heart, entering the heart at the right atrium. The inferior vena cava begins in the lower abdomen and transports blood from the legs, pelvis, and abdomen, entering the heart at the right atrium.
Either of the two main veins, which convey blood from the other veins to the right atrium of the heart. The inferior vena cava, formed by the union of the right and left common iliac veins, receives blood from parts of the body below the diaphragm. The superior vena cava, originating at the junction of the two innominate veins, drains blood from the head, neck, thorax, and arms.
The name of either of the two large vessels that open into the right atrium of the heart.
The principal venous return trunks to the heart.
A substantial blood vessel that enters the heart directly, collecting incoming blood from the entirety of the body.
One of two major veins that receive all the deoxygenated blood in circulation is known as the “venae cavae.” These veins, comprising the superior and inferior vena cava, transport blood to the upper chamber of the heart, the right atrium, from where it is pumped to the lungs.
Originating at the upper part of the chest, close to the breastbone or sternum, the superior vena cava descends through the pericardium, the outer covering of the heart. Eventually, it joins with the right atrium. This vein gathers blood from the upper torso, head, neck, and arms.
Originating in the lower abdomen, the inferior vena cava ascends along the front of the spine, passing behind the liver and through the diaphragm before merging with the right atrium. This vein gathers blood from the legs, pelvic organs, liver, and kidneys.
