BIO-202L: Lymphatic System 2025/2026
Exam Questions and Correct Answers |
New Update
List the three main functions of the lymphatic system. - 🧠 ANSWER
✔✔*Fluid recovery: (absorbs plasma proteins and fluid-10 to 15% (2 to 4 L
per day) from tissues and returns it to blood stream)
-interference with lymphatic drainage leads to severe trauma
*Lipid absorption: (lacteals in small intestine absorb dietary lipids)
*Immunity: (fluids has to go through lymph nodes on way back to
bloodstream where immune cells stand ready)
,Why does it matter that the endothelium of capillaries are only one cell
layer thick? - 🧠 ANSWER ✔✔Capillaries-->distribute oxygenated blood out
to the tissues of your body, and then move deoxygenated blood from the
tissues back into the veins
*Allows oxygen to be easily distributed and allows carbon dioxide to be
easily collected while collecting wastes
Compare and contrast diffusion and osmosis. - 🧠 ANSWER ✔✔Diffusion:
mixing of two or more substances from an area of high concentration to an
area of low concentration
*perfume in a room
Osmosis: diffusion of WATER through a membrane from a solution of low
solute concentration (high water potential) to a solution with high solute
concentration (low water potential)
What is osmotic pressure? - 🧠 ANSWER ✔✔Osmotic Pressure (Colloid;
Oncotic): high concentrate of substance tries to diffuse (disperse) to
become equal through the area BUT this occurs over a membrane.
-The membrane restricts movement of bigger solutes
-In the blood the big solutes are: Albumin (protein)
, *no big particles move
What is hydrostatic pressure? - 🧠 ANSWER ✔✔Hydrostatic Pressure: hose
with holes, fluid "wants" to go out of blood
What is CHP? - 🧠 ANSWER ✔✔Circulatory Hydrostatic Pressure
What is IFHP? - 🧠 ANSWER ✔✔Interstitial Fluid Hydrostatic Pressure
What is COP? - 🧠 ANSWER ✔✔Circulatory Osmotic Pressure
What is IFOP? - 🧠 ANSWER ✔✔Interstitial Fluid Osmotic Pressure
Does filtration actually ever exactly equal reabsorption? - 🧠 ANSWER ✔✔
What is interstitial fluid? Where does it go if it is not reabsorbed into the
capillary? - 🧠 ANSWER ✔✔-The fluid forced out of the arterial ends of
capillary beds, most is reabsorbed, the part that remains in tissue is
interstitial fluid (3-4 L/day)
*when you scrap yourself but not enough to bleed, interstitial fluid seeps
out
*the fluid must make its way back to the bloodstream, the lymphatic
vessels collect this extra protein-containing interstitial fluid (lymph) and
return it to the bloodstream
