What is the role of the thoracic and right lymphatic ducts?
The lymphatic vessels return the lymph to the venous system via two main channels: The right lymphatic duct drains the right thorax, upper limb, head and neck. The thoracic duct drains all lymph from the lower half of the body.
Where thoracic duct opens?
The right lymphatic duct enters the internal jugular vein (IJV) below the level of the clavicle; therefore, it is less likely to be traumatized during cervical surgery. The thoracic duct, on the other hand, opens in the left IJV above the clavicle and can extend up to 6 cm in the neck.
Where does the thoracic duct deliver lymph?
The thoracic duct delivers lymph into junction between left subclavian and left internal jugular veins. Right lymphatic duct delivers lymph into junction between right subclavian and right internal jugular veins.
What drains into thoracic duct?
The thoracic duct drains the lower extremities, pelvis, abdomen, left side of the thorax, left upper extremity, and left side of the head and neck. It originates at the cisterna chyli (when present) and terminates at the junction of the left subclavian and left internal jugular veins.
Is thoracic duct a vein?
In human anatomy, the thoracic duct is the larger of the two lymph ducts of the lymphatic system….

Which part of body is not drained by thoracic duct?
The thoracic duct is the main lymphatic vessel for the return of chyle/lymph to the systemic venous system. It drains lymph from both lower limbs, abdomen (except the convex area of the liver), left hemithorax, left upper limb and left side of face and neck.
What is the function of axillary nodes?
The body has about 20 to 40 bean-shaped axillary lymph nodes located in the underarm area. These lymph nodes are responsible for draining lymph – a clear or white fluid made up of white blood cells – from the breasts and surrounding areas, including the neck, the upper arms, and the underarm area.
Is thoracic duct an organ?
In human anatomy, the thoracic duct is the larger of the two lymph ducts of the lymphatic system. It is also known as the left lymphatic duct, alimentary duct, chyliferous duct, and Van Hoorne’s canal. The other duct is the right lymphatic duct….

What is the thoracic inlet?
The thoracic inlet is the junction between the neck and the chest. A number of neural structures traverse this region.
What is thoracic chamber?
The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum.
What is the purpose of the thoracic duct?
thoracic duct a duct beginning in the cisterna chyli and emptying into the venous system at the junction of the left subclavian and left internal jugular veins. It acts as a channel for the collection of lymph from the portions of the body below the diaphragm and from the left side of the body above the diaphragm.
What is the role of thoracic duct?
The thoracic duct is the largest lymphatic vessel within the human body, and plays a key role in the lymphatic system.
What is the function of the internal thoracic artery?
In human anatomy, the internal thoracic artery (ITA), previously known as the internal mammary artery (a name still common among surgeons), is an artery that supplies the anterior chest wall and the breasts.
What area of the body is drained by thoracic duct?
The thoracic duct drains the lymph from 75% of the body, aside from the right upper right limb, right breast, right lung and right side of the head and neck (which are drained by the right lymphatic duct). Neurovasculature of the neck and superior thorax: Notice the location of the thoracic duct.
