if lymph takes nutrients to those areas where the blood cannot reach, how will oxygen reach those regions, as there is no rbc in the lymph? please explain.

- The lymphatic system acts as a drainage system because, as blood circulates through the body, blood plasma leaks into tissues through the thin walls of the capillaries.
- The portion of blood plasma that escapes is called interstitial or extracellular fluid, and it contains oxygen, glucose, amino acids, and other nutrients needed by tissue cells.
- Although most of this fluid seeps immediately back into the bloodstream, a percentage of it, along with the particulate matter, is left behind.
- The lymphatic system removes this fluid and these materials from tissues, returning them via the lymphatic vessels to the bloodstream, and thus prevents a fluid imbalance that would result in the organism’s death.
