Chapter 20 Lymphatic System
What is the name of the lymph nodes that drain the head and neck region?
cervical
Elephantiasis is
edema formation in response to impaired lymphatic drainage
lymph is
formed from tissue fluid
Which of the following is caused by a viral infection involving the lymph nodes and is called the "kissing disease"?
infectious mononucleosis
A lacteal is located within the
intestinal villus
Thymosin
is a hormone
The spleen, thymus gland, tonsils, and lymph nodes are
lymphoid organs
A person has a severe streptococcal pharyngitis (sore throat.) He is most likely to develop
painful cervical lymph nodes
The subclavian vein
receives lymph from the large lymphatic ducts
The spleen
removes worn-out blood cells from circulation
Lymph from the right arm and the right side of the head and thorax drain into the
right lymphatic duct
The right lymphatic duct and the thoracic duct empty into the
subclavian veins
What happens if the lymphatic vessels and nodes are removed from the right axillary region
the right arm will become edematous
What structure is concerned with the processing and maturation of T lymphocytes
thymus gland
Which lymphoid organ is located the ventral cavity, thoracic cavity, and mediastinum?
thymus gland
What is the term that refers to the removal of palatine tonsils
tonsillectomy
Which of the following is described as partially encapsulated lymph nodes located in the throat area
tonsils
Least characteristic of pharyngeal tonsils
tonsils that are most commonly removed by tonsillectomy
If proteins are allowed to accumulate in the interstitial space, they will
"hold water" and cause edema
Which of the following conditions is most likely to cause a platelet deficiency?
A hyperactive spleen
Why does lymph contain protein
Protein leaks out of the capillaries into the tissue spaces and is absorbed into the lymphatic capillaries
A young woman is diagnosed with breast cancer. She is most apt to have
a sentinel node biopsy before the mastectomy is performed
Which of the following best describes the lymphatic capillaries
they have large pores and follow venous pathways
What is (are) the lymphoid structure(s) that are generally removed during a mastectomy?
Axillary lymph nodes
The inguinal lymph nodes
are located in the groin
What structures are located near the opening of the nasal cavity in the upper throat and are also called the adenoids?
pharyngeal tonsils
Where does lymph originally come from?
right lymphatic duct
An overly active spleen may prematurely remove platelets from the circulation, thereby predisposing the person to
thrombocytopenia and bleeding
