Describe how tissue fluid and lymph fluid form and explain lymph function

Fluid in the spaces between tissues is called interstitial fluid, or 'tissue fluid'. ... Lymph is formed when theinterstitial fluid is collected through tiny lymph capillaries (see diagram), which are located throughout the body. It is then transported through lymphvessels to lymph nodes, which clean and filter it.

Explanation:

lymph function

The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primaryfunction of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
