Chapter 20: lymphatic system
Subclavian vein
Called a lacteal
Least characteristic of the pharyngeal tonsils ,,
Called adenoids ,,
Why does lymph contain protein
Cells that line the lymphatic vessels synthesize protein
What structure is concerned with the processing and maturation of T lymphocytes
Coronary sinus
What structures are located near the opening of the nasal cavity in the upper throat and are also called the adenoids
Pharyngeal tonsils
Thymosin
Plays no known role
The spleen
Removes worn-out blood cells form circulation
What happens if the lymphatic vessels and nodes are removed form the right axillary region
The right arm will become gangrenous from lack of oxygen
Best describes the lymphatic capillaries
They are found only in lymph nodes
Described as partially encapsulated lymph nodes located in the throat area
Thymus gland
Caused by a viral infection involving the lymph nodes and is called the "kissing disease"
Infectious mononucleosis
Where does lymph originally come from
Intersitial spaces
Condition most likely to cause a platelet deficiency
Lymphadenopathy
A young woman is diagnosed with breast cancer, she is most apt to have
A mastectomy and excretion of all axillary lymph nodes; only then is the sentinel node biopsied
If proteins are allowed to accumulate in the interstitial space, they will
Act as antigens and cause an allergic reaction
Lacteal is located within the
Adenoid
What is the term that refers to removal of the palatine tonsils
Adenoidectomy
An overly active spleen May prematurely remove platelets from the circulation, thereby predisposing a person to
Granulocytopenia and infection
The right lymphatic duct and the thoracic duct empty into the
Jugular vein
What is the lymphoid structure that is generally removed during a mastectomy
Liver
The spleen, thymus gland, tonsils, and lymph nodes are
Lymphoid organs
Person has a severe streptococcal pharyngitis (sore throat) he is most likely to develop
Painful cervical lymph nodes
