What are the steps of the lymphatic pathway?

Terms in this set (28)

• The Lymphatic capillaries removes fluid from the tissues.
• Lymph flows through the lymphatic vessels, which contain valves, in order to prevent backflow of lymph.
• Lymph nodes filter the lymph.
• The lymph then enters the 2 ducts.
• The lymph enters the blood.

What is the lymphatic system function?

The lymphatic system is our body’s ‘sewerage system’. It maintains fluid levels in our body tissues by removing all fluids that leak out of our blood vessels. The lymphatic system is important for the optimal functioning of our general and specific immune responses.

What is lymphatic system what are its function?

The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.

What is the correct order of the lymphatic system?

The correct answer is e. Lymphatic capillaries – lymphatic vessels – lymphatic duct – subclavian vein.

What are the main parts of the lymphatic system?

The lymphatic system is a network of very small tubes (or vessels) that drain lymph fluid from all over the body. The major parts of the lymph tissue are located in the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils.

What are 3 main functions of the lymphatic system?

The lymphatic system has three major functions, which are discussed here:

• Tissue drainage;
• Fat transport;
• Immune responses.

How many stages of lymphoma are there?

There are four major stages, along with descriptors and modifiers. The disease is present in only one group of lymph nodes, or, more rarely, in a single organ that does not belong to the lymph system.

What are the stages of lymph node cancer?

Stage III. The disease is present in lymph node groups on both sides of the diaphragm, occasionally with the involvement of other adjacent organs. If the spleen is involved then the disease becomes stage III as well. Stage IV. If the liver, the bone marrow, or the lungs become involved, the disease is in stage IV.

How are the vessels in the lymphatic system formed?

The network of lymph vessels consists of the initial collectors of lymph fluid, which are small, valveless vessels, and goes on to form the precollector vessels, which have rudimentary valves that are not fully functional. These structures then form increasingly larger lymphatic vessels which form colaterals and have lymph-angions (lymph hearts).

How are T cells organized in the lymphatic system?

Lymph nodes. T cells congregate in the inner cortex (paracortex), and B cells are organized in germinal centres in the outer cortex. Lymph, along with antigens, drains into the node through afferent (incoming) lymphatic vessels and percolates through the lymph node, where it comes in contact with and activates lymphocytes.
