Lymph Nodes Histology Diagram Between 400 and 450 lymph nodes are scattered throughout the average human body. they are found along the lymphatic vessels, which carry fluid from the interstitial space into the main circulation. they are particularly abundant in the cervical, axillary, inguinal, perihilar, and intra abdominal areas.

Lymph Node Anatomy Histology Simplified Lymphatic System Youtube The lymphatic system is a system of specialized vessels and organs whose main function is to return the lymph from the tissues back into the bloodstream. lymphatic system is considered as a part of both the circulatory and immune systems, as well as a usually neglected part of students' books. the functions of the lymphatic system complement. Gross anatomy. lymph nodes are bean shaped structures about 0.1 – 2.5 cm in length. the node is enclosed in a capsule and has an indentation on one surface (along one of its long axes) known as the hilum. the hilum is the point at which arteries carrying nutrients and lymphocytes enter the lymph node and veins leave it. The lymphatic vessels transport lymph fluid around the body. there are two main systems of lymph vessels – superficial and deep: superficial vessels – arise in the subcutaneous tissue, and tends to accompany venous flow. they eventually drain into deep vessels. deep vessels – drain the deeper structures of the body, such as the internal. These are about 100 200 100 bean shaped organs, which are found along lymphatic vessels, and which filter micro organisms etc from lymph. this is a diagram of a lymph node, cut away to show the organisation inside, into cortical and medullary regions. primary follicles: lymphoid follicles without a germinal centre.
