Tonsil, Spleen, and Thymus

5–126 The (8) tonsilis a small mass of lymphoid tissue in the mucous mem-

branes of the pharynx and base of the tongue. Tonsils consist of several masses and

are the first line of defense from the external environment. They act as a filter to pro-

tect against bacteria and other harmful substances that may enter the body through

the nose or mouth. Label the tonsil in Figure 5–10.

5–127 The (9) spleenis located in the left upper quadrant (LUQ) of the

abdomen and behind the stomach. It is the largest lymphatic organ in the body.

Although the spleen is not essential to life, it plays an important role in the immune

response by filtering blood in much the same way that lymph nodes filter lymph.

Label the spleen in Figure 5–10.

5–128 Path/o/gens of all types are filtered from the circulating blood by the

macro/phages of the spleen. The spleen also removes and destroys old red blood cells

(RBCs) from circulation. The spleen contains ven/ous sinuses that serve as a storage

reservoir for blood. In emergencies, such as hem/o/rrhage, the spleen can release

blood back into the general circulation.

loss of large amounts of blood in a short period:

__________ / _____ / ____________________

phag/o/cyt/ic cell in the spleen:____________________ / ____________________

5–129 The (10) thymus,also an endocrine gland, is a lymphatic organ. It is lo-

cated near the middle of the chest (mediastinum) just beneath the sternum. Label

the thymus in Figure 5–10.

5–130 During fetal life and childhood, the thymus is quite large, but becomes

smaller with age as it completes most of its essential work during childhood. The

thymus plays an important role in the body’s ability to protect itself against disease

(immunity), especially during the early years of growth.

What CF means immune, immunity, safe?
