Question

Which characteristic of lymphatic capillaries is correct? which characteristic of lymphatic capillaries is correct? they have smaller diameters than blood capillaries. they typically have a rounded, regular appearance in sectional view. they originate as pockets rather than forming continuous tubes. they have thicker walls than blood capillaries?

Answer 1

The correct answer is "they originate as pockets rather than forming continuous tubes".

This is because lymphatic capillaries are small, thin walled vessels that are closed at one end (originate as pockets). This end is located in the interstitial tissue wherein the lymphatic capillaries drain the excess interstitial fluid. Lymphatic capillaries are also located in the digestive tract wherein they act as the conduit for fat absorption (cisterna chyli).
