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
