Lymph Vessels Flashcards
List three main functions of lymph vessels
1) transport immune cells and lmphocytes which are produced in lymph nodes
2) collect and return of tissue fluid that is mainly highly MW proteins . 20% is via systemic circulation and 80% is via venous circulation
3) uptake and transport of long chain (>12C) FAs absorbed by the small intestines then goes to the liver via portal vein. Lymph then goes to the thoracic duct.
which of these is NOT a general feature of lymph vessels (multiple answers)
a) many valves, small, very permeable, and thinned wall
b) always attached to a lymph node
c) not found in cartilage, cornea, and epidermis
d) blindly ending arising tubes in connective tissue
e) found in CNS and bone marrow
f) found as plexus on adventitia on large vessels
b, e
true or false: lymph vessels are ALWAYS associated with lymph nodes
False
true or false: lymph nodes are not considered organs
False
which of these statements about lymph nodules is true?
a) lymph nodules are proliferative structures in lymph nodes that produce lymphocytes and immune cells.
b) a lymph nodule is the closest nodule into which lymph from an organ drains into
c) lymph nodules are always associated with lymph vessels
d) lymph nodules are proliferative structures in lymph vessels that produce lymphocytes and immune cells
a
true or false: the spleen, thymus, and tonsils are all lymphatic organs
True
true or false: all lymph nodes are associated with lymph vessels
True
which of these statements about the sentinel node is true?
a) the sentinel nodule is a proliferative structure in lymph nodes that produce lymphocytes and immune cells.
b) a sentinel nodule is the closest nodule into which lymph from an organ drains into
c) sentinel nodes are found in lymph nodes
d) sentinel nodes are proliferative structures in lymph vessels that produce lymphocytes and immune cells
b
true or false: afferent lymph vessels are arriving at lymph nodes
true
true or false: afferent lymph vessels are leaving lymph nodes
false (efferent)
the subclavian vein and internal jugular vein form the _____ junction
jugulosubclavian
True or false: the thoracic duct terminates in the left jugulosubclavian junction
true
the cisterna chyli occurs in __% of people and is located at __
20%, L2
the thoracic ducts begins in the ____ _____ and ends in the left ________ ________
cisterna chlyi, jugulosubclavian junction
which of the following does NOT drain into the right lymphatic duct (if present):
a) right jugular
b) right subclavian
c) thoracic duct
d) right bronchomediastinal trunk
c
True or false: the thoracic duct drains both lower limbs
True
true or false: the thoracic duct drains the left arm
False (only UPPER arm)
true or false: the thoracic duct drains through the aortic hiatus at T10
False (T12)
List the 5 tributaries of the thoracic duct that drain the left side of the body
2x lumbar trunks, 1x intestinal trunk, 2x descending thoracic trunks
True or false: the thoracic duct enters the diaphragm at T12 (aortic hiatus) between the azygous vein and the descending aorta, posteromedially to the left.
True
True or false: after entering the thorax, the thoracic duct then goes through the posterior mediastinum and then enters the left jugulosubclavian vein junction and into the SVC
True
In the thorax, the thoracic duct receives lymph from the medistinal trunks, as well as _ to _ intercostal trunks on either side
5 to 6
true or false: the thoracic duct receives lymph from the right jugular trunk, right subclavian trunk, and right bronchomediastinal trunk
false (these enter the right lymphatic duct or their adjacent vessels if it is not present, left side enters thoracic duct)
the three lymph drainages of the skin are:
deep cervical lymph nodes, axillary lymph nodes, inguinal lymph nodes
