Chapter 20: Lymphatic System

Which of the following is caused by a viral infection involving the lymph nodes and is called the "kissing disease"?

Infectious mononucleosis

Lymph is

formed from tissue fluid

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 fucts

Lymph from the right arm and the right side of the head and thorax drain into the

right lymphatic duct

The spleen

removes worn-out blood cells from circulataion

The right lymphatic duct and the thoracic duct empty into the

subclavian veins

An overly active spleen may prematurely remove platelets from the circulation, thereby predisposing a person to

thrombocytopenia and bleeding

Where does lymph originally come from?

Interstitial spaces

If proteins are allowed to accumulate in the interstitial space, they will

"hold water" and cause edema

What is (are) the lymphoid structure(s) that are generally removed during a mastectomy?

Axillary lymph nodes

Which of the following conditions is most likely to cause a platelet deficiency?

A hyperactive spleen

What structures are located near the opening of the nasal cavity in the upper throat and are also called the adenoids?

Pharyngeal tonsils

Why does lymph contain protein?

Protein leaks out of the capillaries into the tissue spaces and is absorbed into the lymphatic capillaries

What happens if he lymphatic vessels and nodes are removed from the right axillary region?

The right arm will become edematous

Which of the following best describes the lymphatic capillaries?

They have large pores and follow venous pathways

What structure is concerned with the processing and maturation of T lymphocytes?

Thymus gland

Which lymphoid organ is located in the ventral cavity, thoracic cavity and mediastinum?

Thymus gland

What is the term that refers to the removal of the palatine tonsils?

Tonsillectomy

Which of the following is described as partially encapsulated lymph nodes located in the throat area?

Tonsils

Which of the following is least characteristic of the pharyngeal tonsils?

Tonsils that are most commonly removed by tonsillectomy

A young woman is diagnosed with breast cancer. She is most apt to have

a sentinel node bx before the mastectomy is performed

The inguinal lymph nodes

are located in the groin

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
