Plasma is a liquid makes up about half of the content of blood. Plasma contains proteins that help blood to clot, transport substances through the blood, and perform other functions. Blood plasma also contains glucose and other dissolved nutrients.
Lymph is the fluid that circulates throughout the lymphatic system.
It is formed when the interstitial fluid (the fluid which lies in the interstitial tissues of all body)
is collected through lymph capillaries .
It is then transported through larger lymphatic vessels to lymph node , where it is cleaned by lymphocytes , before emptying ultimately into the right or the left subclavian vein , where it mixes back with the blood .
