what are the parts of the lymphatic system?
pendix, lymph nodes and vessels
functions of the lymphatic system fluid balance, protection, and absorption of fats
one-way system that begins in the tissues and ends when
lymphatic circulation is
the lymph joins the blood
walls (endothelium) flattened epithelial cells, more per-
lymphatic capillaries meable, cells overlap slightly, forming one-way valves,
lacteals absorb fat, arise blindly (closed at one end)
include superficial and deep sets, right lymphatic duct and
lymphatic vessels
thoracic duct
short vessel receives only lymph that comes from the
right lymphatic duct body's superior right quadrant and empties into right
subclavian vein near heart
receives lymph from all parts of the body except those
thoracic duct superior to the diaphragm on the right side; drains into
thee left subclavian vein
first part of the thoracic duct enlarged to form cistern or a
cisterna chyli
temp storage pouch
valves in lymphatic vessels
contraction of lymphatic vessels
movement of lymph toward heart is caused by:
skeletal muscle contraction
breathing
roughly how many lymph nodes are in the body? about 600
distributed throughout the body and makes up special-
lymphoid tissue
ized organs
lymph nodes small masses of lymphatic tissue that filter the lymph

cervical nodes
parts of head and neck
axillary nodes located in armpits
tracheobronchial nodes near the trachea and around the larger bronchial tubes
found between the two layers of peritoneum that form the
mesenteric nodes
mesentry, 100-150 nodes
located in groin region, receive lymph drainage from low-
Inguinal nodes
