(Q.69)  How is lymph formed? Write its functions.

(Ans) 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. From intercellular spaces, it enters into lymphatic capillaries, which join to form lymph vessels, which open into larger veins. Lymph carries digested and absorbed fat from intestine and drains excess fluid from extra cellular space back into blood.
