Plasma is the fluid portion of blood excluding blood cells or corpuscles. It consists of 90% of water. It is the fluid in which blood cells bathe. It consists of many components like immunoglobulins, proteins, hormones, sugars, clotting factors like fibrinogen and electrolytes like Na+ , K+ etc., It helps to maintain osmotic pressure.
Tissue fluid is the fluid present in the interstices of tissues also called interstitial fluid. It slightly differs from the blood plasma because few components like R.B.C’s , platelets can't enter tissue fluid as the walls of blood vessels don't allow. Remaining components like sugars, salts, fatty acids etc are also seen in tissue fluids.
Continuous exchange takes place between blood plasma and tissue fluids for maintenance of electrolyte balance, circulation of proteins etc. Tissue fluid also contains tissue wastes. So tissue fluid components vary from tissue to tissue.
Lymph is also interstitial fluid. The only difference is it is called tissue fluid if it is present in tissues and it is called lymph if it circulates in lymphatic system.
Arteries supply oxygen etc to the tissues and the veins collect deoxygenated (impure blood) from vessels . 90% of the blood goes back into veins whereas 10% remains in the tissues which is the interstitial fluid or lymph. This fluid goes into lymphatic capillaries, then into lymphatic vessels from where the fluid reaches lymph nodes. It is like a dustbin where all the cell wastes (garbage) are dumped . Then lymph enters lymphatic trunks and finally into blood vessels( subclavian vein s) . Lymph apart from bringing the excess protein and interstitial fluid back to blood also protects the body by killing pathogens with the help of lymph cells.
