Kinetics module 14-3
The lymphatic system is a major circulatory system that transports interstitial fluid, waste products, immune cells, and proteins throughout the body. In comparison to other physiological processes, the molecular mechanisms and underlying disease biology for lymphatic disorders are still poorly known, which has hampered progress in therapeutic choices. The lymphatic system’s dysfunction has been linked to a variety of disease phenotypes and has also been proposed as a means of rescuing healthy phenotypes in areas such as cardiovascular disease, metabolic syndrome, and neurological disorders. The roles and structure of the lymphatic system, cell sources for regenerating lymphatic vessels, existing methods for engineering lymphatic vessels, and particular therapeutic areas that will benefit from developments in lymphatic tissue engineering and regeneration will all be addressed in this analysis.

Types of connective tissue – what is connective tissue
The immune system is a diverse array of cells and organs that works together to kill or neutralize pathogens that may otherwise cause disease or death. For most people, the lymphatic system is so closely related to the immune system that the two systems are practically indistinguishable. The lymphatic system is a network of vessels, cells, and organs that removes toxins from the blood and transports excess fluids to the bloodstream. Lymph node swelling during an infection and lymphocyte transport through lymphatic vessels are just two of the many interconnections between these vital organ systems.
The lymphatic system’s primary purpose is to pump and return body fluids to the bloodstream. Blood pressure allows fluid to escape from capillaries, causing fluid to accumulate in the interstitial space—the gaps between individual cells in the tissues. Capillary filtration releases 20 liters of plasma into the interstitial space of the tissues each day in humans. Interstitial fluid is what occurs when the filtrate exits the bloodstream and reaches the tissue spaces. 17 liters were immediately reabsorbed by the blood vessels. But what happens to the three liters that are left? The lymphatic system comes into play at this stage. A collection of vessels, trunks, and ducts drain the excess fluid and return it to the bloodstream. Interstitial fluid that has joined the lymphatic system is referred to as lymph. When the lymphatic system is compromised in some way, such as by cancer cells blocking it or by injury, protein-rich interstitial fluid accumulates in the tissue spaces (and even “backs up” from the lymph vessels). Lymphedema is the abnormal accumulation of fluid that can have significant medical effects.

Lymphatic vessels hold lymph and lymphatic tissue, which may be arranged in lymphatic organs (thymus, spleen, and lymph nodes) or co-create specialized regions of mucosa or submucosa (e.g., in the alimentary canal or respiratory tract – mucosa-associated lymphoid tissue (MALT)). Primary (central) and secondary (peripheral) lymphatic organs are differentiated (tissues). The thymus and bone marrow are primary lymphatic organs, while the spleen and lymph nodes, as well as the specialized regions of mucosa and submucosa, are secondary lymphatic organs.
Lymphatic organs are made up of lymphatic tissue, which is a specialized type of tissue. In reticular fibrous tissue, lymphatic cells (lymphocytes, their developmental types, and plasmatic cells) and macrophages are processed (type of specialized loose connective tissue that operates as an architectural framework). The thymus is an exception, as lymphatic cells are embedded in reticular epithelium, which is connected to organ production (see below).

What happens when lymphatic vessels become severely inflamed, causing blood to clog up the associated vessels of the vasa vasorum? The direction of the related superficial lymphatics becomes apparent through the skin as red lines that are tender to the touch, indicating lymphangitis.
What are the lymphatic system’s three functions? Excess tissue fluid is returned to the bloodstream; leaked proteins are returned to the bloodstream; and ingested fat from the intestine is carried to the bloodstream (thru lacteals)
What do the spleen, thymus, tonsils, lymphatic tissue fragments scattered across the connective tissues, and Peyer’s patches of the intestine all have in common? They are both forms of lymphoid organs or lymphatic tissue aggregates in the body.
The white pulp in the spleen clusters or forms “cuffs” around the central arteries, resembling islands in a sea of what? venous sinuses and splenic cords, regions of reticular connective tissue particularly rich in macrophages; red pulp – all remaining splenic tissue
