Lymphatic System
This category is for questions about the various vessels by which lymph, a watery fluid of leukocytes, circulates through the body, providing transportation for some materials and removing particulate from tissues.

How does cancer begin at the cellular level and how does a healthy immune system work to prevent it?
In cellular level Cancer starts with a molecular mutation that effects the DNA of the cell. When this mutation occurs there are some control mechanisms to repair the effected part of the DNA but sometimes the control mechanisms may not work properly and the control on the dmged cell vanish and the cell starts to proliferate repeatedly. usually normal mutations in the DNA are fixed and if it is not fixable the cell goes down a process called apoptosis and that refers the cell is suiciding but some mutations may occur on some genes which are responsible of the activity of tumor supressing and when this kind of genes are effected the seed of cancer is become sown.
What is the function of tissue fluid?
Tissue fluid accomplishes many functions necessary for the body's cells to survive and work together. The first is support. Cells suspended in fluid are protected from damage caused by the vibrations of an animal's movement. More importantly, tissue fluid acts as a medium for cells to send chemical messages to one another. A related function is that the fluid acts as a waste disposal system for every cell it surrounds.
Are swollen lymph nodes common during pregnancy?
Hi, this is my third pregnancy and I had a swollen lymph gland under my right armpit the last pregnancy and now this one. I went to the doctors the first time round and was assured it was perfectly normal and related to the changes in our bodies, especially producing milk. I was expecting it this pregnancy, but it can be so uncomfortable - not to mention unsightly! It makes it so difficult to shave your armpits with this horrible lump, us women are so lucky the things we go through!
no not really. your white blood cells dont get to work then
Neutrophils are a type of white blood cell and a crucial component of the immune system. They are the body's first line of defense against infections, particularly bacterial and fungal infections. Neutrophils are characterized by their ability to quickly respond to sites of infection or inflammation, where they engulf and destroy pathogens through a process called phagocytosis. They also release enzymes and antimicrobial substances to help eliminate invaders and modulate the immune response.
Lymph channels-- The vessels that transport lymph throughout the body. Lymph is a clear fluid that contains cells important in forming antibodies that fight infection.
The name of enlarged bunches of lymphatic tissue found at various points along the lymph vessels?
These are immaginatively named the Lymph Nodes.
What problem with the immune system can cause severe blood clots?
The immune system has phagocytic cells called macrophages that eat up clots that result from tissue damage or allergic reactions. If these phagocytic cells are not doing there job then these clots do not get eaten up.
yes/ true
What is the purpose of the body?
you stupid you have your own body then you can take an example of it that why di you need a body you are not an organism that you can live without BODY..
Where are the cancerous lymph nodes usually located?
This will depend upon what type of cancer you are asking about, and where the primary cancer is at.
Lymphoma in dogs tends to affect a number of lymph nodes, including the ones above the shoulders and in the back legs. However, a carcinoma would generally first metastasize to the regional lymph node, wherever that may be at.
Which cells in the immune system identify pathogens and distinguish one pathogen from another?
B cells and Helper T cells
Nodes are individual devices or points in a network where data can be created, received, or forwarded, such as computers, routers, and servers. Packets are small units of data transmitted over a network, which include not only the payload (the actual data being sent) but also metadata like the destination address and error-checking information. Together, nodes and packets facilitate communication and data transfer within a network.
Elie Metschnikoff was born in 1845 of Russian Jewish parents. He died in Paris in 1916. He studied natural sciences in Cracow (1862-1864) and then started a life of research, which took him to Italy, Switzerland and Germany. Influenced by Darwin's Origin of Species, his early work was mainly directed towards finding additional proof for the general theory of evolution in the invertebrate kingdom. The rather lucky discovery of phagocytosisin 1882 brought him first notoriety and, later, fame, as the discovery proved to be of first-class importance for the future development of pathology.
