The Lymphatic System. If you’re like most people, you’re more familiar with how the heart and blood vessels work together as part of the cardiovascular system — but you may not know how the lymphatic system fits in. The heart pumps oxygen- and protein-rich blood out through the arteries and into the body’s tissues and organs.
What is the relationship between the lymphatic system and cardiovascular system?
The cardiovascular and lymphatic are both integral parts of the circulatory system. The cardiovascular system basically moves blood throughout the body. While the lymphatic system is part of the circulatory system, comprising a network of conduits called lymphatic vessels. Herein, how does the immune system and cardiovascular work together?

Where do lymphatic vessels drain?
The lymphatic vessels drain into collecting ducts, which empty their contents into the two subclavian veins, located under the collarbones. These veins join to form the superior vena cava, the large vein that drains blood from the upper body into the heart.
What is the lymphatic system?
The lymphatic system is a network of vessels and tissues, just like the circulatory one. In this case, the transported fluid is known as lymph. Furthermore, the lymphatic vessels are tubular structures that run throughout the body. Also, there are between 500 and 600 lymph nodes distributed throughout the body.
How is the lymphatic system related to the circulatory system?
Some people think the lymphatic and circulatory systems are independent of each other. However, the blood vessels aren’t impervious and small amounts of liquid can leak out.
Infections in the lymphatic or circulatory system
The lymphatic system has the function of purifying the body fluids to prevent infections. Blood is usually sterile because the circulatory system is closed.
Infections in the lymphatic system
There’s usually no microbiota in the lymphatic system as immune cells usually eliminate any pathogens early on.

The lymphatic system is fundamental and because it’s related to the circulatory system it needs to maintain a constant amount of fluid in the body. In addition, they work together to protect the body from possible infections.
Why is the lymphatic system important?
The density of the lymphatic vasculature is especially high in the skin and in the respiratory and gastrointestinal systems, which may reflect the importance of the lymphatic system in immune surveillance against foreign antigens and microorganisms.
What organ system is lymphatic?
The lymphatic organ system is unique to vertebrates and is composed of draining lymphatic vessels, LNs, and associated lymphoid organs. Unlike the blood vessels in the circulatory system, lymphatic vessels are blind-ended unidirectional absorptive vessels that transport interstitial fluid, immune cells, and macromolecules to the LNs, and from these back to the blood circulation ( Figure 1 ). The lymphatic vessels are found in almost every vascularized tissue except neural tissue and bone marrow. On the basis of their morphology, function, and hierarchy, lymphatic vessels are classified into capillaries (also known as initial lymphatic vessels), precollectors, and collectors ( Figure 1A ). The capillaries ( Figure 1B) converge into the larger collecting vessels ( Figure 1C ), which drain via chains of LNs ( Figure 1D ), leading eventually to the thoracic duct and the right lymphatic trunk; these drain into the venous circulation via four lymphovenous valves located at the junction of the subclavian and internal jugular veins 18 ( Figure 1E ). The lymphatic vasculature plays an integral role in the regulation of tissue fluid homeostasis, immune cell trafficking, and absorption of dietary fats.
What is the gene for lymphedema?
VEGFR3 was the first lymphedema gene to be identified, and its mutations account for about one half of primary human lymphedemas. Heterozygous mutations in the tyrosine kinase domain of the receptor inhibit VEGFR3 signaling, often in a dominant negative manner, and cause anatomic and functional defects in the lymphatic system, resulting in primary congenital lymphedema also known as Nonne–Milroy lymphedema (OMIM 153100). 117, 118 These patients typically have bilateral lower limb lymphedema, which is usually apparent at birth. VEGFC mutations have also been identified in a Milroy-like disease, which is indistinguishable from Nonne–Milroy lymphedema. 119
What is the role of lymphatic vessels in fat absorption?
Lymphatic vessel role in fat absorption and adipose deposition. A, VEGFC is expressed in a subset of smooth muscle fibers in the intestinal villi and in the circular smooth muscle layer of the intestinal wall, as well as in the arterial SMCs.
What is the origin of lymphatic vessels?
A widely accepted dogma in the field has been that the lymphatic vessels first arise from embryonic veins and thereafter expand by sprouting and proliferation, as initially postulated in 1902 by the American anatomist Florence Sabin 47, 48 and shown by using, eg, Tie2 + cell lineage tracing in mice. 49 However, in 1910, a seemingly contradictory theory by Huntington and McClure proposed that lymphatic vessels arise from mesenchymal LEC progenitors. 50 On the basis of expression analyses, such precursor cells termed lymphangioblasts were described in Xenopus, chicken, and mice. 51 – 53 Grafting experiments by Wilting et al 52 further suggested that the avian lymphatic vasculature has a dual origin, with contribution from both venous- and mesenchymal-derived cells. Recent cell lineage tracing studies have now unequivocally demonstrated that both venous- and nonvenous-derived LECs contribute to the lymphatic vasculature also in mice. 54 – 56
What are lymphatic conduits?
Lymphatic vessels are crucial conduits not only for the trafficking of leukocytes from peripheral tissues to their draining LNs but also for the drainage of soluble antigens. Although tissue resident dendritic cells (DCs) take up antigens and migrate to LNs for antigen presentation, soluble antigens transit to LNs faster than DCs, which is thought to prime the LN for the arrival of the antigen-presenting cells. 27 Interestingly, the entry of soluble antigens from the LN lymphatic sinuses to the reticular LN conduits occurs in a size-dependent manner. Although large antigens are taken up by subcapsular macrophages and paracortical DCs, small antigens (<70 kDa) can directly enter the T- and B-cell zones. 28 Recently, LN LECs were found to contain plasmalemma vesicle–associated protein–positive transendothelial pores that regulate the size-selective entry of lymph-borne antigens to the reticular conduits. 29 Plasmalemma vesicle–associated protein–deficient mice lacked the pore-associated diaphragms, which markedly facilitated the entry of antigens and lymphocytes through the floor of the subcapsular sinus. 29
What is the circulatory system in mammals?
The mammalian circulatory system comprises both the cardiovascular system and the lymphatic system. In contrast to the blood vascular circulation, the lymphatic system forms a unidirectional transit pathway from the extracellular space to the venous system. It actively regulates tissue fluid homeostasis, absorption of gastrointestinal lipids, and trafficking of antigen-presenting cells and lymphocytes to lymphoid organs and on to the systemic circulation. The cardinal manifestation of lymphatic malfunction is lymphedema. Recent research has implicated the lymphatic system in the pathogenesis of cardiovascular diseases including obesity and metabolic disease, dyslipidemia, inflammation, atherosclerosis, hypertension, and myocardial infarction. Here, we review the most recent advances in the field of lymphatic vascular biology, with a focus on cardiovascular disease.
What are the common ways to improve the functions of the lymphatic system?
Lymphedema develops and impedes wound healing when the lymphatic system is compromised and does not function efficiently.
Summary of the lymphatic system
The lymphatic system is critical to the body's proper functioning. One of its primary functions is to drain excess fluid from surrounding tissues and organs and return it to the blood.
