The Lymphatic System

Lymphatic capillaries = Collect excess tissue fluid from around cells and return it to the blood Lymph nodes = Filter foreign particles, cancer, and bacteria from the lymph. They produce and store B-lymphocytes and T-lymphocytes Lymph vessels = Drain the lymph into larger tubes. The lymph moves along vessels very slowly Spleen = Destroys defective red blood cells and recognises antigens to help prevent disease

Transport = To absorb and transport fatty acids and glycerol via lacteals from the small intestine to skin or other organs for storage Defence = Phagocytic white blood cells in the lymph nodes filter the lymph, removing pathogens, cell debris and cancer cells Production = Lymph nodes produce and export B-lymphocytes and T-lymphocytes Drainage = Lymph vessels drain the lymph into larger tubes called lymph vessels

B-lymphocytes = Detect antigens such as viruses and produce antibodies against them T-lymphocytes = Responsible for the development and training of T-cells Phagocytic white blood cells = Filter the lymph, removing pathogens, cell debris and cancer cells Red blood cells = Destroyed by the spleen

<p>Lymphatic capillaries = Narrow, blind-ending tubes that collect excess tissue fluid from around cells and return it to the blood Lymph nodes = Concentrated in the neck, groin, and armpit. Contain phagocytic white blood cells which filter foreign particles, cancer, and bacteria from the lymph. They produce and store B-lymphocytes and T-lymphocytes which detect antigens such as viruses and produce antibodies against them Lymph vessels = Capillaries drain the lymph into larger tubes called lymph vessels. The lymph moves along vessels very slowly. The lymph reaches the thoracic duct where it enters the bloodstream through the left subclavian vein Spleen = Destroys defective red blood cells and recognises antigens to help prevent disease</p> Signup and view all the answers

<p>Transport = To absorb and transport fatty acids and glycerol via lacteals from the small intestine to skin or other organs for storage. Tissue fluid and plasma proteins that have leaked from capillaries are returned into the blood in the subclavian veins Defence = Phagocytic white blood cells in the lymph nodes filter the lymph, removing pathogens, cell debris and cancer cells.

<p>B-lymphocytes = Produced and stored in lymph nodes. They detect antigens such as viruses and produce antibodies against them T-lymphocytes = Produced and stored in lymph nodes. They detect antigens such as viruses and produce antibodies against them Phagocytic white blood cells = Found in the lymph nodes.
