Bronchomediastinal Lymph Trunk[edit]

Diagram of the lymphatic system, including the bronchomediastinal lymph trunk.

The bronchomediastinal lymph trunk is a major lymphatic vessel in the human body that drains lymph from the thoracic region, specifically from the lungs, heart, and mediastinum. It plays a crucial role in the lymphatic system, which is part of the immune system.

Anatomy[edit]

The bronchomediastinal lymph trunk is formed by the convergence of several lymphatic vessels that collect lymph from the bronchial and mediastinal lymph nodes. There are two bronchomediastinal lymph trunks in the body: the right and the left.

Right Bronchomediastinal Lymph Trunk[edit]

The right bronchomediastinal lymph trunk drains lymph from the right side of the thorax, including the right lung, right side of the heart, and the right mediastinum. It typically empties into the right lymphatic duct, which then drains into the right subclavian vein.

Left Bronchomediastinal Lymph Trunk[edit]

The left bronchomediastinal lymph trunk drains lymph from the left side of the thorax, including the left lung, left side of the heart, and the left mediastinum. It usually empties into the thoracic duct, which then drains into the left subclavian vein.

Function[edit]

The primary function of the bronchomediastinal lymph trunk is to transport lymph, which contains immune cells and waste products, from the thoracic region to the venous circulation. This process is essential for maintaining fluid balance in the body and for the proper functioning of the immune system.

Clinical Significance[edit]

Obstruction or damage to the bronchomediastinal lymph trunk can lead to lymphedema in the thoracic region, which is characterized by swelling due to the accumulation of lymph fluid. This condition can occur due to various causes, including cancer, infection, or surgery.

-'''Bronchomediastinal lymph trunk''' is a part of the [[lymphatic system]] that drains [[lymph]] from the [[thoracic cavity]], [[mediastinum]], and the [[lung]]. The term "bronchomediastinal" is derived from "broncho" referring to the bronchus, and "mediastinal" referring to the mediastinum.

-The bronchomediastinal lymph trunks are formed by the confluence of [[lymphatic vessels]] from the [[parasternal lymph nodes]], [[tracheobronchial lymph nodes]], and other lymph nodes located in the thoracic cavity. They are located on either side of the [[mediastinum]], and they drain lymph into the [[venous system]] via the [[subclavian vein]].

-The primary function of the bronchomediastinal lymph trunks is to transport lymph from the thoracic cavity, mediastinum, and the lung to the venous system. This helps in maintaining the fluid balance in the body and also plays a crucial role in the body's immune system by transporting [[white blood cells]] and foreign particles to the lymph nodes where they are filtered out.

-Abnormalities or diseases of the bronchomediastinal lymph trunks can lead to various medical conditions. For instance, blockage or damage to these trunks can result in [[lymphedema]], a condition characterized by swelling due to the accumulation of lymph. They can also be involved in the spread of certain types of cancer, such as [[lung cancer]] and [[breast cancer]], through the lymphatic system.
