1.WHAT ARE LYMPH NODES?
(pg.353)
oval to bean-shaped structures found along the length of lymphatics
2.WHERE ARE THE THREE REGIONS OF LYMPH NODE AGGREGATION IN THE
BODY? (Pg.353)
-Groin
-Armpits
-Neck
3.WHAT ARE AFFERENT LYMPHATIC VESSELS?
(pg.353)
Lymphatic vessels that enter the lymph node at various sites
4.WHAT ARE LYMPHATIC SINUSES?
(pg.353/502)
space between groups of lymphatic tissue
5.WHAT DO EFFERENT VESSELS UNITE TO FORM?(pg.355)
lymphatic trunks
6.WHAT DOES THE LUMBAR TRUNK DO? (pg.356)
drains lymph from the lower extremities, the walls and viscera of the pelvis, the kidneys and adrenal glands, and most of the abdominal wall.
7.WHAT DOES THE JUGULAR TRUNK DO? (pg.356)
drains the head and neck.
8.WHAT DOES THE THORACIC DUCT DO?
(pg.356)
is the main collecting duct of the system
9.WHERE DOES THE THORACIC DUCT EMPTY ALL OF ITS LYMPH INTO? (pg.356)
into the left subclavian vein
10.DESCRIBE THE THYMUS GLAND. (pg.358)
a bilobed mass of tissue located in the mediastinum along the trachea behind the sternum.
11.WHERE IS THE BULK OF OUR LYMPHOID TISSUE LOCATED? (pg.358)
in the lymph nodes.
- WHERE ARE ANTIBODIES PRODUCED
b lymphocytes
13A.DESCRIBE Immunoglobulin A (pg.358)
is found in exocrine gland secretions, nasal fluid, tears, gastric and intestinal juice, bile, breast milk, and urine
13b. IMMUNOGLOBULIN D
(pg.358)
found on the surface of B lymphocytes and is important in B cell activation.
13C. IMMUNOGLOBLIN G
found in tissue fluids and plasma. It attacks viruses, bacteria, and toxins
13D. IMMUNOGLOBULIN E (pg.358)
found in exocrine gland secretions and is associated with allergic reactions, attacking allergy-causing antigens.
13E. IMMUNOGLOBULIN M
(pg.358)
develops in blood plasma as a response to bacteria or antigens in food.
- WHAT IS THE JOB OF KILLER T CELLS? (pg.359)
kill virus-invaded body cells and cancerous body cells. They are also involved in graft rejections.
- WHAT IS THE INTERLEUKIN- 2 RESPONSIBLE FOR?
(pg.360)
stimulates proliferation of T and B cells.
- WHERE DO EFFERENT LYMPHATICS EXIT THE LYMPH NODE? (pg.353)
hilum
- EFFERENT LYMPHATICS UNITE TO FORM HOW MANY LYMPHATIC TRUNKS? (pg.356)
6
- WHAT DO T-CELLS BIND TO?
antigen
19.WHAT ARE PEYERS PATCHES? (pg.358)
found in the wall of the small intestine
- WHAT DOES THE BRONCHOMEDIASTINAL TRUNK DRAIN? (pg.356)
drains the thorax, lungs, heart, diaphragm, and the rest of the liver.
