Lymph. Lymph is a fluid similar in composition to blood plasma. 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.
Why is lymph Colourless?
The blood cells are red because of the interaction between iron and oxygen. So the colour of blood is due to the presence of haemoglobin in RBCS since RBCs are absent in lymph it is colourless.
Why is the Colour of lymph yellow Class 10?

Why is the Colour of the blood red?
Human blood is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. … It’s bright red when the arteries carry it in its oxygen-rich state throughout the body.

How does blood and lymph enter and leave the lymph node?
The lymph vessels enter the nodes at the outer edge, between the capsule and the cortex, and also penetrate deep within the nodes, via channels called conduits. T and B cells leave the node via “efferent” lymphatic vessels, found in the central “medullary” region.
Is RBC Colourless?
Red blood cells contain haemoglobin which provide red colour to the blood. Lymph is colourless becoz it lacks RBC. RBCS contain haemoglobin which provides red colour to the blood.
