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
