What is the bean-shaped part of the lymphatic system?
Lymph nodes: Lymph nodes are bean-shaped glands that monitor and cleanse the lymph as it filters through them. The nodes filter out the damaged cells and cancer cells.
Are lymph nodes bean-shaped organs?
Lymph nodes are small kidney- or bean-shaped organs, usually less than one inch (2.6 cm) in length. They are found in clusters of several nodes in many regions of the body, especially in the neck, armpits, trunk, and groin. The exterior of each lymph node is connected to many smaller lymphatic vessels.

What are lymphatic capillaries?
Lymph or lymphatic capillaries are tiny thin-walled vessels, closed at one end and located in the spaces between cells throughout the body, except in the central nervous system and non-vascular tissues. Lymphatic capillaries are slightly larger in diameter and have greater oncotic pressure than blood capillaries.
What are the 4 organs of the lymphatic system?
The lymphatic system consists of all lymphatic vessels and lymphoid organs. For example, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer’s patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs.
What are lymphatic capillaries called?
Lymph capillaries or lymphatic capillaries are tiny, thin-walled microvessels located in the spaces between cells (except in the central nervous system and non-vascular tissues) which serve to drain and process extracellular fluid. Upon entering the lumen of a lymphatic capillary, the collected fluid is known as lymph.
Where are lymphatic capillaries located?
Lymph capillaries are found in all regions of the body except the bone marrow, central nervous system, and tissues, such as the epidermis, that lack blood vessels. The wall of the lymph capillary is composed of endothelium in which the simple squamous cells overlap to form a simple one-way valve.
What are organs of lymphatic system?
The tissues and organs that produce, store, and carry white blood cells that fight infections and other diseases. This system includes the bone marrow, spleen, thymus, lymph nodes, and lymphatic vessels (a network of thin tubes that carry lymph and white blood cells).
