Question

What is lymph and what is its function in human body?

Answer 1

Lymph is the fluid that circulates throughout the lymphatic system. It is formed when the interstitial fluid (the fluid which lies in the interstices of all body tissues)[1] is collected through lymph capillaries. It is then transported through larger lymphatic vesselsto lymph nodes, where it is cleaned by lymphocytes, before emptying ultimately into the right or the left subclavian vein, where it mixes back with the blood.

Answer 2

Through the pores present in the walls of capillaries some amount of plasma, proteins and blood cells escape into intercellular spaces between the tissue to form the the tissue fluid or lymph.

Function :-

1. Lymph drains into lymphatic capillaries from the intercellular spaces,which join to form large lymph vessels that finally open into larger veins.

2. Lymph carries digested and absorbed fat from intestine and drains excess fluid from extra cellular space back into the blood.
