Lymphatic system of the reproductive organs in pregnancy

Abstract

The lymphatic system, the first primitive form of which is seen in fish and amphibians, arose In response to the development of the blood vascular system. Until complexity of the organism necessitated a closed system of vessels, transport of nutrient and waste materials was carried out by direct exchange with the external environment. With development of the blood vessels, however, some structure was needed to remove excess fluid from the tissues. The role of the lymphatic system, therefore, in any part of the body, is the removal of excess proteinaceous tissue fluid which, in general, is derived from the circulating plasma by a process of filtration through the capillaries.
