WHAT IS KNOWN AS IYMPH |
Lymphatic vessels, or simply lymph vessels, are tubular structures responsible for carrying lymph throughout the human body, much as blood vessels convey blood. These vessels are a vital part of the lymphatic system, which supports the human immune and circulatory systems, filters toxins and waste products from somatic cells and tissues, and aids in the production of certain protein molecules. The lymphatic system has a one-way cycle that moves lymph upwards through the human body. There are two kinds of lymphatic vessels, afferent lymph vessels and efferent lymph vessels. The afferent vessels are similar to veins in that they transport fluid into the lymph nodes, while the efferent vessels are similar to arteries, carrying filtered lymph away from the lymph nodes. Lymph is a solution that begins in the circulatory system as blood plasma and then converts to a fluid known as an interstitial or intercellular fluid. This fluid is responsible for delivering hormones, oxygen, and various nutrients to cells throughout the body. As it leaves the cells, it bathes them, taking waste products away with it. |
