MICROANATOMY

Detailed explanation-1: -Throughout your body, interstitial fluid (fluid found in the spaces around cells) leaks from blood capillaries into your tissues. Lymph capillaries pick up this fluid and help return it to your circulatory system.

Detailed explanation-2: -Interstitial fluid is removed via lymphatic drainage and returned to the venous circulation. In organs located in the pleural, pericardial and peritoneal spaces, some interstitial fluid filters through the organ’s serosal surface into the surrounding fluid space and, then, is also taken up into the lymphatic system.

Detailed explanation-3: -As soon as the interstitial fluid enters the lymph capillaries, it is called lymph. Returning the fluid to the blood prevents edema and helps to maintain normal blood volume and pressure.
