Question 1

Valves within lymphatic collecting vessels serve what purpose?

Accepted Answer

Preventing backflow and ensuring unidirectional lymph transport

Answer

Bicuspid valves in collecting lymphatics ensure that lymph flows only toward the thoracic duct and right lymphatic duct, preventing retrograde flow.

Question 2

Which layer of the skin contains the superficial lymphatic capillary network targeted in MLD?

Accepted Answer

Superficial dermis (papillary layer)

Answer

The initial lymphatic capillaries are densely packed in the superficial dermis, which is why MLD uses very light pressure applied to the skin surface.

Question 3

What is the approximate normal filtration-reabsorption balance at the capillary level?

Accepted Answer

About 90% is reabsorbed by blood capillaries; 10% enters lymphatics

Answer

Under normal Starling forces, roughly 90% of capillary filtrate is reabsorbed into venules, and the remaining 10% (with proteins) is collected by lymphatics.

Question 4

The spleen differs from lymph nodes in that it filters which fluid?

Accepted Answer

Blood

Answer

Unlike lymph nodes that filter lymph, the spleen filters blood directly, removing old red blood cells, pathogens, and debris from the bloodstream.

Question 5

Anastomoses in the lymphatic system refer to what?

Accepted Answer

Connections between lymphatic vessels that allow alternative drainage routes

Answer

Lymphatic anastomoses are cross-connections between vessels that enable lymph to be rerouted around blocked or removed nodes, which is the basis of MLD detour pathways.
