100% CORRECT
What does the lymphatic system do? - correct answer ✔✔Maintains fluid balance in the
internal environment.
-interstitial fluid is absorbed by tissue cells and reabsorbed by the blood
-absorbs fat in the intestine with special lymph structures called lacteals
(Chapter 31) lymphatic system - correct answer ✔✔Jan 2021
edema - correct answer ✔✔puffy swelling of tissue from the accumulation of fluid that can
cause tissue distruction
the lymph vessels act as "drains " thats- - correct answer ✔✔collect excess tissue fluid and >
venous blood
lymph - correct answer ✔✔clear, water- appearing fluid found in the lymphatic vessels.
-This fluid is isotonic
Interstitial Fluid - correct answer ✔✔-fills space between cells
-has a lower protein concentration
lymphatic capillaries - correct answer ✔✔-microscopic
-blind end vessel that are the origin of lymphatic vessels
-lymphatic and blood capillary network work side by side
,-lymphatic capillaries merge from the lymphatic vessels and drain into the lymphatic trunk
what type of cells are lymphatic capillaries made up of? - correct answer ✔✔flattened
endothelial cells (simple Squamous)
lymphatic vessel contains - correct answer ✔✔-thin walls
-valves (these valves are one way)
-lymph nodes
as the lymph flows from thin walled capillaries into vessels with a larger diameter.. the walls
become THINER or Thicker? - correct answer ✔✔thicker- similar to arteries and veins
Lymphatic vessel functions - correct answer ✔✔-high molecular weight substance and even
particulate matter from interstitial space
-lacteals absorb fat and other Nutricia from the small intestine
-PROTIENS THAT ACCUMULATE IN THE Tissue can only return to the blood through lymphatics
chyle - correct answer ✔✔milky lymph found in lacteals after digestion contain 1-2% fat.

, where is the cisterna chyli located? - correct answer ✔✔Anterior to the first two lumbar
vertebrae.
How is lymph circulated through the body - correct answer ✔✔through muscles contraction
and relaxation
lymphatic pump - correct answer ✔✔Lymph moves in the right direction due to the large
number of valves
The flow of lymph can be visualized in a ______________ - correct answer ✔✔Lymphangiogram
lymphatic pump - correct answer ✔✔-inspiration establishes fluid pressure gradient
-skeletal muscles contractions increase flow
-total volume of lymph depends on depth on inspiration
-lymph enter and return rates very
- depends on the amount of physical activity and other factors
What is the shape of a lymph node? - correct answer ✔✔oval shaped structure
where does lymph enter the lymph node. - correct answer ✔✔afferent vessels
-moves slowly through a sinus drain into efferent lymphatic vessel
Lymph nodes act as a biological ___________? - correct answer ✔✔filter
Lymph emerges by one or more ______________ vessels - correct answer ✔✔efferent
Trabeculae - correct answer ✔✔extend from the capsule toward the center node
