Question

limphatic capillaries allow flow of large molecules such as proteins in and out to lymph circulation ? True or False?

Answer 1

Tthis statement is FALSE

REASON:

Lympathic capillaries are present in the interstitial space between the cells.

The structure of lymphatic capillaries resemble the blood capillaries, but they have a slight larger diameter compared with blood capillaries.

The fluid present inside the lymphatic capillaries are call lymph.

when the pressure of the fluid in the interstitial space is greater than the pressure inside the lymphatic capillary, the fuild will enter the lymphatic capillaries.

But the lymphatic capillaries act as a one way mechanism that is the the fluids ans protein entered inside the lymphatic capillaries cannot go back out of the cappilaries.

Usually plasma poteins and WBC are higher in he lymph compared to the Blood, but these molecules cannot diffuse out of the lymphatic cappilaries.

The lymph present inside the lymphatic capillaries are carried in to the lymph vessel----> lymph node ------> ultimately drained into the venous system(left supracalvicular vein)
