Question

what is the difference between blood plasma and lymph?

Answer 1

One difference is a matter of definition. Blood plasma is the liquid part of blood, always contained in blood vessels. Lymph is the fluid contained in lymphatic vessels. Lymph is similar to blood plasma in composition, except for being much lower in protein. Lymph coming from the small intestine during digestion of a meal is often so loaded with lipids that it has a milky look; hence the lymphatic capillaries of the intestinal wall are called lacteals.
