• D. When blood flows through lymphatic vessels.

Answer 1

The correct option is A

When blood squeezes through pores of blood capillaries.

There is another type of fluid along with blood also involved in transportation. This is called lymph or tissue fluid. Through the pores present in the walls of capillaries some amount of plasma, proteins and blood cells escape into intercellular spaces in the tissues to form the tissue fluid or lymph.
