Lymph, tissue fluid, and plasma are all fluids that exist in the body, but they differ in their location and composition.
Lymph is a clear fluid that circulates through the lymphatic system. It is formed when tissue fluid enters the lymphatic vessels and is transported through the lymphatic vessels and lymph nodes. Lymph contains immune cells and waste products and is important for the immune system.
Tissue fluid is a fluid that surrounds the cells in tissues. It is formed when blood plasma filters out of the capillaries and into the spaces between cells. Tissue fluid supplies nutrients and oxygen to the cells and removes waste products.
Plasma is the liquid part of the blood. It contains water, electrolytes, proteins, hormones, and waste products. Plasma carries nutrients, hormones, and waste products to and from the cells and tissues in the body.
In summary, lymph is a fluid that circulates through the lymphatic system, tissue fluid is a fluid that surrounds the cells in tissues, and plasma is the liquid part of the blood that carries nutrients, hormones, and waste products to and from the cells and tissues in the body.
