MICROANATOMY

Detailed explanation-1: -Lymphatic capillaries are permeable to proteins. False; Lymph flows towards the heart, where it is emptied into veins. Lymph always flows away from the heart. Because lymph vessels are very low-pressure conduits, movements of adjacent tissues are important in propelling lymph.

Detailed explanation-2: -The lymphatic capillaries function to absorb the excess protein-containing interstitial fluid and return it to the blood stream. Lymph always flows away from the heart. Lymphatic capillaries are permeable to proteins.

Detailed explanation-3: -The normal permeability of the lymphatics was studied with dyes of graded diffusibility. Their walls proved readily permeable for those highly diffusible pigments that the blood capillaries let through easily, but retained those that the latter retained.

Detailed explanation-4: -Lymphatic capillaries have greater permeability than blood capillaries and can absorb large molecules such as proteins and lipids.

Detailed explanation-5: -Lymphatic capillaries are much more permeable than blood capillaries. Proteins in the interstitial space that can’t enter the blood capillaries can enter the lymphatic capillaries with ease.
