What is lymph ? How is it formed ? Mention its major function ?

- Lymph is a colourless, mobile, fluid connective tissue.

- When blood is flowing with pressure in the arteries, some water and dissolved solutes are filtered out from blood plasma into the tissue spaces, to form interstitial fluid.

- Some of the tissue fluid enters the tiny channels called lymph vessels to form

lymph.

- An elaborate network of vessels called the lymphatic system collects this fluid and drains it back to the major veins.

Function of Lymph:

- Lymph is an important carrier for nutrients, hormones, etc.

- Lymph has specialised lymphocytes, that provide immunity.

- Plasma proteins synthesized by the liver are taken by the lymph into blood for circulation.
