MICROANATOMY

Detailed explanation-1: -It is derived from blood plasma as fluids pass through capillary walls at the arterial end. As the interstitial fluid begins to accumulate, it is picked up and removed by tiny lymphatic vessels and returned to the blood. As soon as the interstitial fluid enters the lymph capillaries, it is called lymph.

Detailed explanation-2: -Lymph rich in fat molecules is known as chyle and is transported to the veins through the thoracic duct. When an injury happens to the thoracic duct during surgery or trauma, the chyle will leak into the peritoneum causing chylous ascites.

Detailed explanation-3: -Lymphatic fluid is derived from plasma. It leaks out of the capillary walls because of pressure exerted by the heart or osmotic pressure at the cellular level.

Detailed explanation-4: -Most of the lymphatic vessels have valves like those in veins to keep the lymph, which can clot, flowing in the one direction (toward the heart). Lymphatic vessels drain fluid called lymph from tissues throughout the body and return the fluid to the venous system through two collecting ducts.
