Lymphatic system

The lymphatic system consists of lymphatic capillaries and vessels, lymph nodes, the spleen, the thymus, the tonsils, and lymph itself. Some of the fluid that is deposited into the tissues from the blood is taken up by lymphatic capillaries where it becomes lymph. Lymphatic capillaries and vessels have valves that prevent back flow, ensuring one-way flow of lymphatic fluids. Lymphatic capillaries eventually converge to form lymphatic vessels, which are similar in comparison to veins. Lymphatic vessels eventually converge to empty back into the bloodstream via the right lymphatic duct, emptying into the right subclavian vein and the thoracic duct, emptying into the left subclavian vein. Lymphatic vessels on the right side of the head, neck, chest and the right upper limb converge into the right lymphatic duct while the rest of the body’s lymphatic vessels converge into the thoracic duct. The lymphatic organs, which consist of the tonsils, the spleen, the thymus and the lymph nodes, are made up of lymphatic tissues that contain cells like lymphocytes and macrophages. These organs are…

Introduction The Central Nervous System (CNS) has been considered devoid of lymphatic vasculature, and for years, the theory of the nonexistence of the lymphatic system in the brain has been accepted as a biological/anatomical fact. This very basic fact of neuro-anatomy has recently been upset by two independent studies, revealing that the brain does, in fact, have a functional lymphatic system. Although this study was originally done on mice brains, there have been similar findings in human…

human body has two major circulatory systems: the blood and lymphatic systems. Although the blood vascular system and the lymphatic system operate in parallel and share some anatomical features, the two vascular systems have had very different fates in science and medicine, as they display distinct structural and functional features. While the blood system has been extensively studied and examined, the lymphatic system has been neglected and considered as less important compared with the blood…

The Lymphatic system consists of the tonsils, lymphatic vessels, the thymus, lymph nodes, and the spleen, and its functions include immunity, lipid absorption, and tissue fluid recovery (Saladin, Sullivan, & Gan, 2015). The lymphatic system consists of 6 main types of lymphatic cells: B Lymphocytes (B Cells), Dendritic Cells, Macrophages, Natural Killer (NK) Cells, Reticular Cells, and T Lymphocytes (T Cells). The unique function of each cell is briefly described below. B Lymphocytes (B Cells):…

How does lymphatic functions during good health and bad? The lymphatic system works to protect the body to stop it getting an infection or a virus it does this with the help of cells such as lymphocytes which travels in between the nodes through channels called lymphatic, which meet ducts that empty into blood vessels this is how the lymphocytes enter the blood. There are 3 types of lymphocytes; B-lymphocytes (B-cells), T-lymphocytes (T-cells), Natural killer (NK) cells each of these react…

Lymphatic System’s Role in Immunity The human body has built in defense mechanisms to aid against foreign substances, pathogens, toxins and diseases. The type of immunity used by the body depends on the type of pathogen and whether that pathogen has already entered the body. In cases where the pathogen is inside the body, an internal defense is used to aid in fighting the pathogen. The body may start running a fever or start inflammation to rid itself of the pathogen. In cases where the…

The lymphatic system is an important part of the immune system and is a network of tissues and organs that help rid the body of toxins, waste and other unwanted material. The functions of the lymphatic system are fluid balance, fat absorption, and defense. The encapsulated lymphatic organs are the lymph nodes, thymus, and spleen. The mucosa-associated lymphoid tissue (MALT) consists of a vast network of nonencapsulated lymphatic tissue found in and beneath the mucous membranes lining the…

The body is a complex organism, which is composed of systems that work together to maintain homeostasis. The immune and lymphatic system is one of the systems that protect the body from disease-causing bacteria, viruses and organisms. There are two ways that they fight and protect the body from disease, nonspecific and specific. Nonspecific is how the body generally fights off diseases. This includes fever and the swelling of your lymph nodes. Specific immunity is how the body protects itself…

Lymphatic Malformation Lymphatic Malformation is something you are born with. It is very rare for a person to get it. But it interests me and hope this will inform you. I am going to explain what is Lymphatic Malformation, what it does, and how someone I know experienced it in her life. What is Lymphatic Malformation? According to NORD, “Lymphatic malformations are rare non-malignant masses consisting of fluid-filled channels or spaces thought to be caused by the abnormal development of the…

complex networks of lymphatics which have a fundamental immunological function protecting intrathoracic organs such as the lungs, pleura, oesophagus and mediastinum. These networks drain interstitial fluid from the lungs, chyle from the gastrointestinal tract, and white blood cells and other immune components (Brotons et al., 2012). Thoracic lymphatics are involved in several diseases that most thoracic surgeons are concerned about. The most important pathologies affecting thoracic lymphatics…
