Thus, the lymph vessels of the lungs, pericardium, heart, esophagus, trachea and esophagus, thymus flow into the circuit nodes are mainly around the trachea, the anterior and posterior mediastinum and the inner surface of the chest.
Thoracic lymph nodes are divided into parietal and visceral.
Parietal sites: nodi lymphatici intercostales prevertebrales are in the back of the intercostal spaces, and on the sides of the vertebral bodies; nodi lymphatici parasternales surround the internal thoracic artery.
Visceral sites: nodi lymphatici mediastinales anteriores et posteriores.
To the front of mediastinal Read more [...]
Lymph vessels and nodes of the trachea
The mucous membrane of the trachea has two network of lymphatic capillaries. Vascular plexus is located in the submucosal layer and the connective tissue between the cartilages of the trachea. Lymphatic vessels flow into the trachea and the tracheal tracheobronchial nodes (Fig. 445).
445. Arrangement of the lymph nodes in the neck and mediastinum (the DA Zhdanov).
1 - nodi tracheales; 2 - a. carotis communis; 3 - ductus thoracicus; 4 - v. subclavia; 5 - nodi lymphatici axillares; 6 - nodi tracheobronchiale; 7 - nodi bronchopulmonales: 8 - nodi pulmonales; Read more [...]
The roots of the lymphatic system in the lining of the colon is a single-layered network of lymphatic capillaries wide diameter of 20-200 microns. Lymph from the mucosa flowing in well-developed submucosal plexus, which is pumping vessels muscle layer and partly serous membrane. In a two-layer serosa lymphatic network in the muscle - single-layered.
The lymphatic vessels of the appendix are located near an artery in his mesentery, which may be interrupted by small units, then the back end ileal bypass part of the small intestine and enter the obodochnokishechnye iliac nodes (nodi lymphatici Read more [...]
The skin of the scalp, ear, face and neck a single-layer network of lymphatic capillaries in the subcutaneous tissue are connected to vessels. Lymph from the occipital, temporal and parietal areas poured into the occipital nodes (nodi lymphatici occipitales), located behind the mastoid process and the beginning of sternocleidomastoid muscle, and the BTE nodes (nodi lymphatici retroauriculares).
From the skin of the forehead, eyelids, ear and ear canal, the lateral part of the skin of the upper jaw and lips lymphatic flow into the superficial parotid nodes (nodi lymphatici parotidei superficiales), Read more [...]
The mucous, fibrous and muscular layer of the pharynx lymphatic capillaries form a single-layer network. The lymphatic vessels are formed from these networks in each layer of the pharynx, are involved in the formation of the submucosal plexus and adventitia, which are connected, and the vessels of the mucous membrane of the nasal cavity, hard and soft palate, tonsils, and tongue.
Efferent (Extrahepatic) vessels throats are divided into three groups: the upper, middle and lower. They take in the retropharyngeal lymph and the deep cervical nodes (Fig. 450).

Lymph vessels and nodes of the chest wall
The skin of the breast has a two-layer network of lymphatic capillaries, merging into the subcutaneous lymphatic vessels, bound to the surface and pectoral axillary nodes. Pectoral nodes are located at the lower edge of the pectoralis major muscle. Deep lymphatics chest wall collect lymph from the capillaries periosteum of ribs, intercostal muscles, the internal chest fascia and the parietal pleura, and then accompany the intercostal vessels and nerves and end at the rear and front intercostal nodes. Intercostal nodes located near the spine and parallel Read more [...]
