What is the thoracic vena cava?

The superior vena cava is a large, significant vein responsible for returning deoxygenated blood collected from the body back into the heart. It is present within the superior and middle mediastinum. The superior vena cava handles the venous return of blood from structures located superior to the diaphragm.

At the level of the inferior border of the 1st right costal cartilage, the left and right brachiocephalic veins converge to form the superior vena cava, which goes on to drain into the right atrium of the heart.

Where is the internal thoracic artery situated?

The internal thoracic artery arises a few centimeters away from the origin of the subclavian artery. The artery then descends along the inner wall of the anterior rib cage. It is located about two to three centimeters on either side of the sternum and is slightly medial to the nipple.

Variations. Bifurcation of each internal thoracic vein is common. The left internal thoracic vein may bifurcate between ribs 3-4 or remain as a single vein. The right internal thoracic vein may bifurcate between ribs 2-4 or remain as a single vein.

Where is the intercostal vein?

The intercostal veins run above the intercostal arteries, which run above the intercostal nerves. The posterior intercostal veins drain into the azygos vein (right side), and hemiazygos and accessory hemiazygos veins (left side). The latter two veins ultimately drain into the azygos vein.

Where is internal jugular vein located?

The internal jugular vein is a run-off of the sigmoid sinus. It arises in the posterior cranial fossa and exits the cranium through the jugular foramen, located at the base of the skull.

Which vein drains the ankle and foot?

In human anatomy, there are two anterior tibial veins. They originate and receive blood from the dorsal venous arch, on the back of the foot and empties into the popliteal vein. The anterior tibial veins drain the ankle joint, knee joint, tibiofibular joint, and the anterior portion of the lower leg.

Where does the subclavian vein drain into?

The left subclavian trunk directly drains into the thoracic duct, and the right subclavian trunk continues to form the right lymphatic duct, which enters at the right venous angle (junction of the internal jugular vein and subclavian vein).

Which vein drains the calcaneus?

The peroneal vein is doubled and drains the lateral aspect of the foot surrounding the calcaneal confluent and the ankle, passing upward and posteriorly through the calf, as well as passing posteriorly and medially to the fibula.

Where does small saphenous vein drain into?

The blood from the small saphenous vein typically drains into the popliteal vein located around the knee.

Where is the saphenous vein located?

Around the knee, the great saphenous vein runs behind the medial epicondyle of the femur, a protrusion on the inner side of the leg. As it runs up the thigh, it remains on the medial side.

Which veins drain blood into the superior vena cava?

The superior vena cava is formed by the left and right brachiocephalic veins—also referred to as the innominate veins—on the right side of the upper chest, posterior (behind) to the lower border of the first costal cartilage.

Which general regions of the body are drained by the superior vena cava and the inferior vena cava?

These blood vessels carry oxygen-depleted blood from various regions of the body to the right atrium of the heart. The superior vena cava delivers blood from the head and chest area to the heart, while the inferior vena cava returns blood from the lower body regions to the heart.

What organs drain in portal vein?

Where does the right inferior phrenic vein drain?

The Inferior Phrenic Veins drain the diaphragm and follow the course of the inferior phrenic arteries. The right ends in the inferior vena cava.

Which of the following veins usually drains into the right atrium?

The great cardiac vein, the middle cardiac vein, and the small cardiac vein all drain into the coronary sinus (which opens into the right atrium). The anterior cardiac veins drain directly into the right atrium.

Where does the right superior intercostal vein drain into?

The right superior intercostal vein drains the upper two to three intercostal spaces and can empty into either the azygos or the right brachiocephalic vein. Other tributaries of the azygos vein include esophageal, bronchial, mediastinal, and pericardial veins.
