They belong to the lymphatic system, which is a network of vessels and also organs that carry and also filter lymph, que es visiorax a fluid which contains leukocyte, proteins, as well as waste items. Lymph nodes are connected by lymphatic vessels and also are purposefully positioned to receive as well as refine lymph.
Head as well as Neck
In the head and neck area, lymph nodes lie in numerous areas. The cervical lymph nodes are located in the neck as well as are split right into anterior and also posterior chains. The submandibular lymph nodes are located underneath the reduced jaw, while the submental lymph nodes are located underneath the chin. Furthermore, lymph nodes can be located along the sides as well as rear of the neck.
Furthermore, lymph nodes exist in the face area. The preauricular lymph nodes lie in front of the ear, while the parotid lymph nodes are located near the parotid gland. Other facial lymph nodes include the buccal, submandibular, as well as submental lymph nodes.
In the scalp, occipital lymph nodes can be discovered at the base of the head, while shallow parotid lymph nodes are positioned near the ear. The deep parotid lymph nodes lie within the parotid gland itself.
In addition, lymph nodes can be located in the oral cavity. The tonsillar lymph nodes are located near the tonsils, and the sublingual lymph nodes can be located under the tongue.

Upper Body
In the upper body, lymph nodes are located in the axillary region, commonly known as the underarm. These axillary lymph nodes are accountable for receiving lymph from the upper limbs, breast wall surface, and breast cells.
Additionally, lymph nodes are located in the thoracic region. The mediastinal lymph nodes are placed within the mediastinum, which is the main area of the chest. They receive lymph from the lungs, esophagus, as well as various other frameworks within the thoracic tooth cavity.

Additionally, lymph nodes are present in the mammary region, near the breasts. The pectoral lymph nodes lie within the pectoral muscle mass, while the subareolar lymph nodes are positioned under the areola of the nipple area.

- Mediastinal lymph nodes
- Mesenteric lymph nodes
- Pectoral lymph nodes
- Subareolar lymph nodes
Reduced Body
In the lower body, lymph nodes are located in several areas. In the inguinal area, which is the groin area, inguinal lymph nodes can be located. These nodes receive lymph from the reduced arm or legs, outside genitalia, and lower stomach wall surface.
Additionally, lymph nodes are positioned in the pelvic area. The usual iliac lymph nodes are placed near the usual iliac arteries, while the interior and exterior iliac lymph nodes lie along the corresponding capillary. These nodes receive lymph from the pelvic organs, such as the bladder, womb, and also anus.

- Common iliac lymph nodes
- Inner iliac lymph nodes
- Outside iliac lymph nodes
Various other Locations
Along with the main places discussed above, lymph nodes can likewise be found in various other locations of the body. For example, lymph nodes are present in the axilla, or armpit, region. These axillary lymph nodes get lymph from the upper limbs, upper body wall surface, and also breast cells.
Furthermore, lymph nodes can be found in the popliteal area, which is the back of the knee. The popliteal lymph nodes receive lymph from the lower limbs as well as feet.
- Axillary lymph nodes
- Popliteal lymph nodes
Conclusion
Lymph nodes are distributed throughout the body and play a vital function in preserving a healthy immune system. Comprehending their areas permits medical care specialists to analyze and also identify diseases or infections that may affect these nodes. From the head as well as neck to the top and lower body, lymph nodes function as vital elements of our immune defense, filtering lymph as well as assisting in the fight versus infection.
