What makes up the lymphatic system?

circulatory system

What system does the lymphatic system work in conjunction with?

remove waste and excess fluids from the tissues

what do the lymphatic and circulatory systems do ?

lymph

A thin watery fluid composed of intercellular, or intersitial fluid

when plasma diffuses into tissue spaces

when is lymph formed?

water, digested nutrients, salts,hormones, oxygen carbon dioxide, lymphocytes and metabolic wastes such as urea

what is lymph composed of?

lymph

when fluid enters the lymphatic system it is known as what?

lymphatic vessels

What is located throughout the body in almost all of the tissues that have blood vessels?

lymphatic capillaries

What are small, open-ended lymph vessels that act like drain pipe?

true

lymphatic capillaries pick up lymph tissues throughout the body

yes

do capillaries then join together to form larger lymphatic vessels which pass through lymph nodes

contractions of skeletal muscles against lymph vessels

what causes lymph to flow through vessels?

valves

what do lymphatic vessels have to keep lymph flowing in only one direction?

lacteals

specialized lymphatic capilllaries found in the area of the small intestine

digested fats or lipids

what do lacteals pickup?

chyle

lymph mixed with lipids is called what?

thoracic duct

lacteals transport the chyle to the bloodstream through what?

lymph nodes

what popularly called glands are located all over the body usually in groups or clusters?

lymph nodes

small round or oval masses ranging in size from a pinhead to an almond

carbon, cancer cells pathogens and dead blood cells

lymph nodes filter the lymph and remove what impurities?

lymphocytes (a type of leukocyte or white blood cell) and antibodies

what does the lymphatic tissue in the nodes produce?

yes

does purified lymph, with lymphocytes and antibodies added leave the lymph node by a single vessel?

Right lymphatic duct and thoracic duct

what is the name of the 2 lymphatic ducts that the larger lymph vessels drain into?

right side of head and neck, the right chest and the right arm

right lymphatic duct ia a short tube that recieves all purified lymph from where?

right subclavian vein

the right lympatic duct empties purified lymph into the blood where?

thoracic duct

larger tube that drains lymph from the rest of the body

left subclavian vein

where does the thoracic duct empty into

cisterna chyli

What is a large pouch like structure located at the start of the thoracic duct

true

the cisterna chyli serves as a storage area for purified lymph before lymph returns to the bloodstream

tonsils spleen and thymus

3 types of lymphatic tissue found in the body

true

tonsils are masses of lymphatic tissue that filter interstitial fluid

palatine ,pharyngeal ,llingual

name the 3 types of tonsils

palatine tonsil

located on each side of the soft palate

pharyngeal (also called adenoids) tonsil

located in the nasopharynx (the upper part of the throat

lingual tonsil

located on the back of the tongue

true

cisterna chyli also recieves chyle from the intestinal lacteals

beneath the left side of diaphragm and in back of the upper part of the stomach

Where is the spleen located

produces leukocytes and antibodies, destroys old blood cells stores erthycoytes to release into bloodstream if excessive bleeding occurs destroys thrombocytes and filters metabolites and wasres from the body

what does the spleen do

thymus

mass of lymph tissue located in the center of the upper chest

yes

is the thymus replaced by fat and connective tissue after puberty

produces antibodies and manufacture lymphocytes

What does the thymus do in early life?

lymph nodes

what takes over for the thymus?

adenitis

inflamation or infection of the lymph nodes(occurs when large quanties of pathogens or cancer cells enter the lymph nodes and infect the tissue

antibiotics warm moist compresses or an incise to drain the node

What is the treatment for adenitis?

hodgkin's diseae

chronic malignant disease of the lymph nodes ( symptoms swelling of lymph nodes fever night sweats weight loss fatigue and pruritus (itching)

Chemotherapy and radiation

Treatments for hodgkin's disease

true

hodgkin's disease is usually curable

lymphangitis

inflamation of lymphatic vessels usually resulting from an infection in an extremity

red streak extending up arm or leg from source of infection fever chills pain

symptoms of lymphangitis (treatment antibiotics rest elevation of infected part warm compressess

splenomegaly

enlargement of the spleen results from an abnormal accumulation of red blood cells mononucleosis and cirrhosis of the liver

true

splenomegaly can lead to death if the spleen would rupture

true

symptoms of splenomegaly are swelling abdominal pain destruction of red blood cells can lead to anemia

true

spleen can be surgically removed

tonsillitis

inflamation infection of the tonsils usually involves the pharyngeal (adenoid) and palatine tonsils

true

treatment for tonsilitis antibiotics throat irrigations rest and pain medicine chronic or enlargement may indicate need for surglcal removal
