The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel.

  • Lymph is clear or white fluid that travels through vessels, moves within tissues and work to keep all the parts of the body clean. (news-medical.net)
  • Another major fact is that the lymph channels serve to spread the cancer cells throughout the body. (news-medical.net)
  • It does this by filtering and draining lymph away from each part of the body. (hopkinsmedicine.org)
  • One of the lymphatic system's major jobs is to collect extra lymph fluid from body tissues and return it to the blood. (kidshealth.org)
  • This process is important because water, proteins, and other substances are continuously leaking out of tiny blood capillaries into the surrounding body tissues. (kidshealth.org)
  • Lymph capillaries are found in all regions of the body except the bone marrow , central nervous system , and tissues, such as the epidermis , that lack blood vessels. (daviddarling.info)
  • By doing this, they were "moving" the lymph fluid around the body, which is why your legs would instantly shrink and skin would feel softer. (mindbodygreen.com)
  • An auxiliary system, the lymphatic system, is composed of vessels that collect lymph from body tissues. (encognitive.com)
  • In addition, a system of shunts allows blood to bypass the capillary beds and helps to regulate body temperature. (encognitive.com)
  • Blood vessels - Lymph, a fluid rich in immune system cells and signaling chemicals, travels from the blood into body tissues via capillaries. (chop.edu)
  • Capillaries are tiny blood vessels with a key role in managing fluid balance in the body. (medicalnewstoday.com)
  • The lymphatic system carries lymph through the body. (medicalnewstoday.com)
  • Lymphatic plexuses (networks) are made up of tiny lymphatic capillaries, which are located in most of the tissues of the body. (dummies.com)
  • Our body movements and muscle contractions press on the lymphatic vessels carrying lymphatic fluid, causing it to move and to circulate throughout our body. (haaretz.com)
  • The lymphatic system carries lymph fluid throughout the body, collecting bacteria, viruses and waste products. (adoptspecialneeds.org)
  • The arteries divide into very thin vessels called capillaries that form a network between the cells of the body. (equinekingdom.com)
  • lymphatic v's the capillaries, collecting vessels, and trunks that collect lymph from the tissues and carry it to the blood stream. (thefreedictionary.com)

  • These vascular malformations of dilated capillaries appear in the upper and lower layers of the skin on the face, neck, arms, and legs. (encyclopedia.com)
  • They're found mostly around the neck, armpits, groin, thorax, knees, and elbows, and their function is to filter and monitor the lymph for foreign particles such as pathogens (bacterial and viruses) and cancerous cells before it returns to the blood. (dummies.com)

  • First, they remove from the lymph foreign particles dumped into the tissue fluid from cells. (scienceclarified.com)
  • The large particles enter the system at the terminal lymph vessels or terminal lymphatics , through openings like gills in a fish. (edmesh.org.uk)
  • Because of their unique structure, lymph capillaries are able to absorb larger particles from the tissues, such as proteins, cells, bacteria and other large substances, which cannot be absorbed by blood capillaries. (lymphedemablog.com)
  • An ample amount of moisture (water) in the blood contributes to the fluidity of the lymph fluid, leading to better circulation of the lymph fluid. (buybooksontheweb.com)
  • Massage can also promote blood and lymph circulation to an extent. (buybooksontheweb.com)
  • The pulmonary circulation carries the blood to and from the lungs. (encognitive.com)
