Lymphatic System:
Lymphatic system is a complex network of tissue and organ which help the body to get rid of unnecessary material. [KAZ (2015)]
Function of lymphatic system:
It has three functions:
1. Returns the excess tissue fluid to blood.
2. From the digestive system it absorbs fat and fat-soluble material.
3. It defense against the diseases or invading microorganism.
[Douketis (2013)]
LYMPHATIC SYSTEM COMPONENTS
It consists of:
1. lymph
2. lymph Vessels
3. Organs
[MacGill (2015)]
Lymph:
It is a fluid that is derived from blood plasma. It passes from capillary walls to the arterial end. Whenever tissue fluid started to accumulate, the lymphatic vessels collect it and remove it and returned to the blood. By this action it prevents it to cause edema and to maintain the normal blood pressure and volume. The tissue fluid is called lymph as it enters into the lymph capillaries. [MacGill (2015)]
Lymphatic vessels:
It carries fluid away from the tissue. The smallest vessel of lymphatic system is the lymph capillaries. Except bone marrow, central system and tissues they are present in all over the body. Lymph capillary is made up of

They are small and they have bean-shaped structure which is made up of lymphatic tissue. Along the lymphatic routes, lymph nodes are found throughout the body. They are widely spreaded in the areas around the axillary nodes, inguinal nodes, cervical nodes and popliteal nodes. Actually the lymph contains lymphocyte which enters from the bloodstreams through specialized vessels called high endothelial venules. Along with the antigens the lymph drains in to the nodes through in coming lymphatic vessels and by travelling through the lymph nodes it comes in contact with lymphocytes and it activate them now lymph’s carry deactivated lymphocytes’ with them and they exist the node through the outgoing vessel and then it enters in to the blood streams from where they are distributed throughout the
Veins transport blood to the heart and lungs at low pressure after receiving it from the capillaries. Valves inside the veins keep blood moving in one direction. The human body's arterial system branches out from one main artery, the dorsal aorta. Like veins, arteries have three layers: an outer layer of tissue, an inner layer of epithelial cells and a layer of muscle in between.
As a result, these cells form a clump that is commonly referred to as a tumor (neoplasm), especially when the immune system is malfunctioning. Tumors can be benign, harmless and easily taken out or malignant. Malignant tumors block tissues and organs from functioning with each other. Once cancer cells become metastasized, they break away from a host tumor. These free-floating
All these cells float in the liquid plasma, which is mostly water. Plasma also contains nutrients, electrolytes, hormones and protein antibodies to fight infection.
“Lymphoid tissue, cells and organs that make up the lymphatic system, such as white blood cells, bone marrow, and the thymus spleen, and lymph nodes” (The Editors of Encyclopedia Britannica). Lymphoid tissue is a big part of Hodgkin disease, so to fully understand the disease an individual must learn that the lymphoid tissue is very important for the human body. Lymphoid tissue is extremely important as an immune response and it also helps protect the body from infection and invaders. Simply, Hodgkin disease is the expansion of lymphoid tissue and the existence of Reed-Sternberg cells that are found in the lymph nodes. Reed-Sternberg cells “are large, often multinucleated with a peculiar morphology and an unusual immunophenotype, that does
Task 1: a) The immune system has two ways of defending the body, nonspecific and specific immunity. There are many barriers in the human body which protect and defend the body from any unwanted, potentially dangerous pathogens that may try to enter. When the body is dealing with a pathogen for the first time, the nonspecific response will be put to use. The biggest barrier that the body has is the skin. The skin contains many layers, the outermost layer of the skin is known as the stratum corneum and it consists of around 15-20 layers of dead skin.
The Immune System, which the cell attacks, is responsible for warding off enemies from the body. It consists of many parts, most notably lymph nodes, white blood cells, and lymphocytes.. When an infection is spotted, white blood cells swarm it and attack it. If the white blood cells cannot handle the infection, lymph nodes create lymphocytes, which attack the infection with renewed force, and help prevent infection in the future (Human Biology 149).
This accelrated blood flow enables enables lymph to moved throughout the body more effeitnly than it normally does. Lymp is an immune system fluid that helps to gather and get rid of unwanted substances from the body. As such when lymph gets ciruclated throughout the body at a much faster rate, it essnetally boosts the immune system and makes it more cpapable of fighiing colds and
About The lymphatic system is a system in the human body that runs alongside the body parts that make up the circulatory system. Blood vessels leak a fluid called lymph; the lymphatic system works to take the lymph and transfer it back into the circulatory system. The lymphatic system is open to cells containing diseases such as cancer cells, but along the lymphatic system are lymph nodes which filter out any unwanted cells. When the lymph nodes fail to function or have been removed the lymphatic system and circulatory system are both left vulnerable to these disease carrying cells; this it’s what’s known as lymphedema.
Introduction Inflammation, as described by Gilroy and Lawrence (2008), is a primitive response that aids against damage or injury to tissue. It is also described as the first step of restoring injured tissue back to its normal physiological purpose. We as humans, depend on inflammation because our survival and health is determined by how efficient the inflammatory response is when it comes to kick-starting the process of wound healing. In this essay, I will be discussing the anatomical pathology of inflammation, i.e. the causes, signs/symptoms and treatment of inflammation as well as discussing some articles pertaining to the mechanism of inflammation, how inflammation promotes the healing process, what occurs when one wants to induce inflammation,
The dermis which is the second layer is more active and hosts capillaries, blood vessels, elastin and also fibroblasts. Dermis also has certain polysaccharides like glycosaminoglycans which keep the cellular activity towards the
Now the digestive system is what helps us get some of the energy we need but the muscular system is what moves the food around our digestive track an out of our bodies. One of the biggest diseases that the muscular system has to deal with is the Iron Maid diseases. This malfunction is where the makeup of your muscles is remade and when they are impacted in a forceful way they turn to bone. This make the patient unable to move and it very slowly creates a pressure on their chest and stomach and makes them unable to do anything ever again.
The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
The nerve supply also comes from her celiac plexus innervating the liver mixture of sympathetic and parasympathetic fibers. These ribs reach the liver by the hepatic artery. Liver Physiology The liver performs many functions in the body such as: • Production of bile: The liver excretes bile to the bile duct and thence to the duodenum. Bile is necessary for digestion of food.
Due this process, it allows the lymphatic system to monitor the invading microbes. The lymphatic vessels also carry a clear fluid that it bathes in the body’s tissues that is known as lymph. Another organ is lymph node that is has specialized compartments where the immune system there and can encounter antigens. It shaped is small and bean shapes that are there in neck, armpits, abdomen and groin. As mentioned above, that there is lymphatic vessels, so that the immune cells and all the foreign particles will enter then exit through outgoing lymphatic vessels.
The circulatory system is made up of the heart, arteries, arterioles, capillaries, venules and veins. Arteries carry oxygenated blood (except the pulmonary or umbilical arteries) away from the heart whilst veins bring unoxygenated blood back to the heart. Capillaries are the thinnest of the blood vessels at only one cell thick, this is where blood diffuses from capillaries into venules and then veins. The heart is the giver of life. Without the heart and blood, the body is unable to function.
