Lymphatic system

Lymph nodes of the mammary glands

The woman's mammary gland has a complex anatomy of the structure. It lies on the large pectoralis muscle and partly on the front dentate.

Lymphatic vessels and nodes of the upper limb

The upper extremity has superficial and deep lymphatic vessels, which are directed to the ulnar and axillary lymph nodes. Surface lymphatic vessels are located near the subcutaneous veins of the upper limb and form three groups: lateral, medial and anterior.

Lymphatic vessels and nodes of head and neck

From the organs of the head lymph vessels deliver lymph to the lymph nodes, which lie in the form of small groups on the border of the head and neck [occipital, mastoid (ear), parotid, occlusal, facial, submandibular, chin].

Lymphatic vessels and nodes of the thoracic cavity

In the chest cavity, parietal (parietal) lymph nodes located on the respective walls (anterior, posterior and posterior) and visceral (internal) located in the thoracic cavity on the lymph flow path from its internal organs are isolated.

Lymphatic vessels and nodes of the abdominal cavity

In the abdominal cavity, visceral (internal) and parietal (parietal) lymph nodes are also isolated. Visceral lymph nodes (nodi lymphatici viscerales) are located near the unpaired visceral branches of the abdominal aorta and their branching (near the celiac trunk, the hepatic, splenic and gastric arteries, the superior and inferior mesenteric arteries and their branches).

Lymphatic vessels and pelvic nodes

In the pelvic cavity and on its walls there are lymph nodes, into which the lymph vessels flow from the nearby organs, as well as the lymph vessels of the lower extremities.

Lymphatic vessels and nodes of the lower limb

On the lower extremity, the surface lymphatic vessels located above the superficial fascia are distinguished, and deep ones located near the deeply lying blood vessels (arteries and veins), as well as popliteal and inguinal lymph nodes.

Lymphatic trunks and ducts

The lymph from each part of the body, passing through the lymph nodes, collects into the lymphatic ducts (ductus lymphatici) and lymphatic trunks (trunci lymphatici). Six such large lymphatic ducts and trunks are isolated in the human body.

Lymphatic vessels

Lymphatic vessels (vasa lymphatica) are formed by the fusion of lymphatic capillaries. The walls of the lymph vessels are thicker than the walls of the lymphocapillaries.

The lymph nodes

Lymph nodes (nodi lymphatici) are usually located near the blood vessels, often near large veins, usually in groups - from a few knots to ten or more.
