Concept Explanation
 

Lymph as Fluid Connective Tissue

It is another fluid connective tissue that floats inside specialised vessels known as lymph vessels.

Composition:-

It is a colourless fluid containing high concentration of WBC's (specialised lymphocytes). composition of lymph is similar to blood with the exception of absence of RBC's, platelets and some plasma proteins and in having less calcium and phosphorous than their levels in the blood. It also contains all the ions, present in the blood plasma.

Lymphatic System :-

It is an elaborate network of vessels, which collects the interstitial fluid (tissue fluid), along with some protein molecules drains it back into the major veins. The lymphatic vessels are present in all tissues (except the central nervous system and cornea).

Formation of Lymph :-

  • As the blood passes through the capillaries of the arterial system into the tissues, some water along with many water soluble substances come out in the spaces between the cells of tissues.
  • But a very small amount of proteins come out from the capillary with the plasma (leaving the larger proteins and most of the formed elements in the blood vessel). The fluid thus, released out is called interstitial fluid (tissue fluid) or Extracellular Fluid (ECF). After entering the lymph vessel, the ECF becomes lymph.
  • Functions of Lymph :-

    Lymph performs the following important functions :-

  •  It acts as an important carrier of nutrients, hormones, etc.
  •  Absorption of fat also occurs through lymph in the lacteals present in the intestinal villi.
  •  Also helps in the renewal of ECF. releasing them into the lymph.
  •  Helps in keeping tissue cells moist.
  • The lymph first reaches the lymph nodes like thymus, tonsils, Payer's patches, spleen, etc. in the body.
  •
