LYMPHATIC SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Lymph vessels have to be “milked” because the lymphatic system is a ____
A
low-pressure, pumpless system.
B
high-pressure, pumpless system.
C
low-pressure, pump system.
D
high-pressure, pump system.
Explanation: 

Detailed explanation-1: -Lymphatic vessels collect and filter lymph (at the nodes) as it continues to move toward larger vessels called collecting ducts. These vessels operate very much like your veins do: They work under very low pressure, have a series of valves in them to keep the fluid moving in one direction.

Detailed explanation-2: -The lymphatic system utilizes both extrinsic pumps, which rely on the cyclical compression and expansion of lymphatics by surrounding tissue forces, and intrinsic pumps, which rely on the intrinsic rapid/phasic contractions of lymphatic muscle.

Detailed explanation-3: -The anatomy of collecting lymphatic vessels appears to be similar to that of comparable veins in that they both are low-pressure vessels vested with a muscle layer and intraluminal valves.
