When lymph capillaries in the body drain what happens?

The lymph trunks drain into the lymph ducts, which in turn return lymph to the blood by emptying into the respective subclavian veins. There are two lymph ducts in the body: the right lymph duct and the thoracic duct.

Are lymph capillaries blind-ended?

Lymphatic capillaries are blind-ended tubes with thin endothelial walls (only a single cell in thickness). They are arranged in an overlapping pattern, so that pressure from the surrounding capillary forces at these cells allows fluid to enter the capillary (see the image below).

Does lymph get into the lymphatic capillaries?

Upon entering the lumen of a lymphatic capillary, the collected fluid is known as lymph. Each lymphatic capillary carries lymph into a lymphatic vessel, which in turn connects to a lymph node, a small bean-shaped gland that filters and monitors the lymphatic fluid for infections.

Where does the lymph vessels drain into?

Collecting ducts: Lymphatic vessels empty the lymph into the right lymphatic duct and left lymphatic duct (also called the thoracic duct). These ducts connect to the subclavian vein, which returns lymph to your bloodstream. The subclavian vein runs below your collarbone.

Where does the lymph go when it leaves the capillaries?

From the lymphatic capillaries, lymph enters collecting lymphatic vessels, which accompany blood vessels. In general, the superficial collecting lymphatic vessels in the skin travel with superficial veins, whereas the deep collecting lymphatic vessels of the trunk and digestive viscera travel with the deep arteries.

Why are lymphatic vessels so permeable to bacteria?

Although the high permeability of lymphatic capillaries allows the uptake of large quantities of tissue fluid and large protein molecules, it also allows any bacteria, viruses, or cancer cells in the loose connective tissue to enter these capillaries with ease. These pathogenic agents can then travel throughout the body via the lymphatic vessels.

What do cancer cells look like in distant lymph nodes?

These are known as distant lymph nodes. If cancer cells settle in the distant lymph nodes, it is known as secondary or metastatic cancer. When the cancer cells in the distant lymph nodes are examined under a microscope, they look like cells from the primary cancer.

What kind of fluid is in the lymphatic vessels?

Once inside the lymphatic vessels, this fluid is called lymph (clear water). Any blockage of the lymphatic vessels causes the affected body region to swell with excess tissue fluid, a condition called edema. From the lymphatic capillaries, lymph enters collecting lymphatic vessels, which accompany blood vessels.
