The lymphatic system works in three ways. It helps to control the balance of the body’s fluids by draining and cleansing fluid that seeps from the circulatory system during normal cardiovascular circulation. As fluid leaves the circulatory system it enters the tissue cells and whilst the majority of it diffuses back into the vessels of the circulatory system, the remainder enters the open ends of the lymph vessels. The lymphatic system also works with the villi in the digestive system to help deliver fats and absorbed nutrients in the digested food we eat, back to the circulatory system. This fluid is not called

Blood is a circulating tissue consisting of three types of cells: red blood cells, white blood cells, and platelets. These cells are suspended in a liquid known as plasma. Plasma is similar to salt water in composition. It carries dissolved proteins, such as antibodies, hormones, and clotting factors, and nutrients such as glucose, amino acids, salts, and minerals.

The organs that make up the respiratory system are; nose and nasal cavity, mouth, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, diaphragm and lungs.

Microscopically, the lymph nodes demonstrate extensive architectural destruction by sheets of plasma cells that form between the cells of the lymph nodes. The hyaline-vascular changes in the cells are inconspicuous or absent, while the changes with plasma cells can be seen more often in scans and tests (The Hematologist).

Page 1 Hello! My name is Alex. I am a nineteen year old girl who is about to bring you through my journey of a disease I never imagined would happen to me, well at least at this age. Three days into my nineteenth birthday I was diagnosed with Hodgkin’s lymphoma. If you don’t know what that means, as I didn’t the first time I was told it is the dreaded C word.

The objective of the circulatory system is to transport blood throughout the human body through a series of interconnected blood vessels. Major components of this system include the heart, blood and blood vessels (arteries, veins and capillaries). Furthermore, in the pulmonary circuit, the heart works in tandem with the lungs to oxygenate returning venous blood in preparation for distribution throughout the body via the arteries. In the systematic circuit, blood

One of the most important organs of the lymphatic system within the body's blood filter process is the spleen. This organ does a variety of things to help keep healthy blood available to be shipped to the body for pathogen-fighting purposes. The spleen normally is about a fist size. The oval clump of blood vessels intertwined with strands of connective tissue is separated into two parts. The blood vessels that make up a large content of the spleen, are called splenic sinusoids. The organ is normally found in the left upper part of the abdomen, above the stomach, it is mostly protected by the lower ribs. This particular organ is a definite vital part in cleaning the body's blood supply. In most cases people can live without their spleen (Rettner, 2013). This of course comes with extra precautions to help fight infections but a normal life can exist. The dark purplish red mass helps to filter the blood through its many passageways of blood vessels and is soft in texture.

In the blood there is dissolved oxygen that is taken to the human body cells and also gets rid of the waste products of the respiration which is water and carbon dioxide. Blood also gives heat all around the human body, hormones, nutrients, salts, urea and also enzymes.

Cancerous lymphocytes can travel to many parts of the body, including the lymph nodes, spleen, bone marrow, blood, or other organs, and form a mass called a tumor. Lymphocytes are the warriors of the immune system (Marieb & Hoehn). The body has two main types of lymphocytes that can develop into lymphomas: B-Lymphocytes (B-cells) and T-lymphocytes (T-cells) (Lymphoma.org). T-cells and B-cells protect

The respiratory system is divided into two main parts, the upper respiratory and lower respiratory tract. The upper respiratory tract consists of the nasal cavity which is a hollow space behind the nose, it is lined with mucous membrane and small hairs, which traps smaller particles entering with the air, the nasal cavities main purpose is to heat, humidify and filter the air before it passes into the lungs (Whittemore and Cooley, 2009 ). The sinuses are hollow areas in the bones of the skull and are lined with a mucous membrane that open into the nasal cavity, they help to keep the skull light. The pharynx is around 12.5 cm long and joins the posterior oral and nasal cavities to the larynx and oesophagus. It is a member of both the respiratory system and the digestive system as it allows food and air to pass through it, the food and air are both directed through their own passage ways which is controlled by the epiglottis, which is a flap of elastic tissue that acts like a lid to cover the trachea in order to avoid substances from entering the larynx (Callentine, 2015). The larynx is located at the upper part of the air passage the walls of the larynx are made up of muscle and cartilage, it contains the vocal cords, sound is produced by air passing through the larynx on the way to the lungs and connects the pharynx to the trachea (Wilkins and King, 2002). All of these organs which are situated in the respiratory system are located outside of the chest cavity.

The lymphatic system produces and stores cells that helps the body battle infection and diseases. The lymphatic system contains the following components: bone marrow, thymus, spleen, and lymph nodes. The lymph system allows the body to move fluids and cells outside the blood and circulatory system. The lymph system is the most important passageway
