Lymphatic (IMMUNE) and Urinary Systems – notes Function of the Lymphatic System – – – Major Organs of the Lymphatic System 1. _____________________- The clear fluid found outside the cells which bathes the tissues. It is collected, filtered, and transported by the lymphatic system from around the tissues to the blood of the circulatory system. 2. _____________________– collect lymph fluid from the tissues of the body 3. _____________________- transport lymph fluid to the circulatory system. 1. The lymphatic system lacks a _____________________organ 2. To propel lymph, vessels rely on: Pulsations of nearby _____________________ Movement of _____________________ throughout the body Contractions of _____________________ muscle in the walls of the lymphatic vessels 4. _____________________ - are the main cells involved in the immune response – Two main varieties __________________and ____________________ – T cells and B cells protect the body against antigens _____________________ – anything the body perceives as foreign. Ex: Bacteria and their toxins; Viruses; Mismatched RBCs; or cancer cells 1. __________________- Manage the immune response; Attack and destroy foreign cells 2. __________________- Produce plasma cells, which secrete antibodies; Antibodies immobilize antigens 5. _____________________- Primary lymphatic organs of the body; Found within connective tissue and along lymphatic vessels – 2 basic functions: – _____________________ –remove microorganisms, dead cells, and debris – _____________________ system activation – monitor and attack antigens 6. _____________________- Largest lymphatic organ; Site of white blood cell production; Immune surveillance and response; Cleanses the blood by removing dead red blood cells 7. _____________________ - Only lymphoid organ that does NOT fight antigens, it functions as “T-cell academy” – modifies T-cells 8. _____________________and Adenoids - Simplest lymphatic organs; Trap bacteria and other antigens which work their way into the follicles where they are destroyed _____________________ lymph fluid Returns leaked_____________________to circulatory system Produces and modifies cells of immune system to __________________infection Disorders of the Lymphatic System Function of the Urinary System 1. _____________________- Accumulation of lymph fluid caused by blockages in the lymphatic vessels 2. Severe combined immunodeficiency (SCID) syndrome – _____________________ disorder in which a person is born missing T cells (white blood cells that identify and attack perceived “invaders”) and affect the function of the B cells (white blood cells that produce antibodies against infection) 3. An _____________________ disorder is a condition that occurs when the immune system mistakenly attacks and destroys healthy body tissue. There are more than 80 different types of autoimmune disorders. – Rhuematoid Arthritis – Type I Diabetes – Psoriasis – Vitiligo ● Regulate _____________________ balance (fluid volume) of the body ● _____________________ waste products from the blood ● _____________________ blood pH ● Regulate ion concentrations in the blood Major Organs of the Urinary System 1. _____________________– main organs of the urinary system; filter harmful poisons like urea from the blood 2. _____________________–stores urine 3. _____________________– tubes that connect kidneys to bladder 4. _____________________– tube thru which urine exits the body Wastes Removed 1. Any substance that is useless to the body by the Kidneys – _____________________, Drugs, _____________________, Salts, hydrogen ions, excess _____________________ Excretion and other body systems Disorders of the Urinary System 2. Metabolic Wastes - produced by the body during cellular respiration; CO2 – expelled by the lungs, but some in urine and Nitrogenous waste – Excretion: Separation of waste from body fluid and waste and eliminating them o _____________________ system – Carbon dioxide o _____________________System – water, salts, lactic acid, urea o _____________________ System – water, salts, carbon dioxide, lipids, bile, pigments, cholesterol o _____________________ System – metabolic waste, toxins, drugs, hormones, salts, hydrogen ions, and water – – _____________________– Calcium, phosphate, uric acid, and protein crystallize in the kidneys _____________________- Acute (sudden) kidney failure is the sudden loss of the ability of the kidneys to remove waste and concentrate urine. – Can be caused by: Dehydration, Hemorrhage, Injury, Septic shock, Serious illness, Surgery
