What are the major lymphatic trunks?
There are four pairs of lymph trunks: jugular lymph trunks, subclavian lymph trunks, bronchomediastinal lymph trunks, and lumbar lymph trunks. … The intestinal lymph trunk and the thoracic lymph duct contain chyle, a mixture of emulsified fats from the intestines and lymph fluid.
What are the 5 lymph trunks?
There are four pairs of lymph trunks: jugular lymph trunks, subclavian lymph trunks, bronchomediastinal lymph trunks, and lumbar lymph trunks. In addition, the intestinal lymph trunk is unpaired.
Where is the Bronchomediastinal trunk located?
Bronchomediastinal trunks (right and left): located deep in the thorax; each bronchomediastinal trunk drains lymph originating from the lung, anterior thoracic viscera and the musculature of the anterolateral body wall above the level of the umbilicus.
Where are jugular trunks?
The jugular trunks are small short paired lymphatic trunks, each one draining one side of the head and neck, forming an important terminal part of the lymphatic system 1-3.
What is the largest lymphatic organ?
Spleen: This largest lymphatic organ is located on your left side under your ribs and above your stomach. The spleen filters and stores blood and produces white blood cells that fight infection or disease.
What color is lymph fluid?
Lymph is a clear-to-white fluid made of: White blood cells, especially lymphocytes, the cells that attack bacteria in the blood.
What is the driving force for lymph movement?
What is the driving force for Lymph movement? Lymph movement is driven by the contraction of adjacent skeletal muscles, pressure changes in the thorax during breathing and the pulsations of nearby arteries.
Where do lymph ducts drain?
A lymph duct is a great lymphatic vessel that empties lymph into one of the subclavian veins. There are two lymph ducts in the body—the right lymphatic duct and the thoracic duct. The right lymphatic duct drains lymph from the right upper limb, right side of thorax and right halves of head and neck.
What trunk drains lymph from the lower extremities?
The thoracic duct is the largest and most important lymphatic channel of the body (see Figs. 6-11 and 6-13). 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.
What drains into the right Bronchomediastinal trunk?
The parasternal nodes drain into the bronchomediastinal trunk. The intercostal nodes also drain into the bronchomediastinal trunk. … Pulmonary nodes to bronchopulmonary nodes to inferior tracheobronchial nodes to right superior tracheobronchial nodes to right paratracheal nodes to right bronchomediastinal trunk.
Where is lymph found?
Most of our lymph nodes are in clusters in the neck, armpit, and groin area. They’re also found along the lymphatic pathways in the chest, abdomen, and pelvis, where they filter the blood. When a person has an infection, germs collect in the lymph nodes.
What lymphatic trunks do you know?
There are five pairs and an unpaired lymph trunk: Jugular lymph trunks. Subclavian lymph trunks. Bronchomediastinal lymph trunks.
What are left and right jugular lymphatic trunks?
The deep lymphatic vessels of the head and neck arise from the deep cervical lymph nodes. They converge to form the left and right jugular lymphatic trunks: Left jugular lymphatic trunk – combines with the thoracic duct at the root of the neck. This empties into the venous system via the left subclavian vein.
Where does the right jugular trunk drain?
It is formed by vessels that emerge from the superior deep cervical lymph nodes and unite to efferents of the inferior deep cervical lymph nodes. On the right side, this trunk ends in the junction of the internal jugular and subclavian veins, called the venous angle.

Do lymph trunks have valves?
Like veins, the lymphatic tributaries have thin walls and have valves to prevent backflow of blood. There is no pump in the lymphatic system like the heart in the cardiovascular system.
