Question

In the human circulation, the lymph

• A. Transports oxygen to brain
• B. Transports $C{O}_2$ to lungs
• C. Returns interstitial fluid back to heart
• D. Contains RBCs, leucocyte, and more protein as compared to blood

Answer 1

The correct option is C Returns interstitial fluid back to heart

Lymphatic system is a network present throughout all tissues in the body. It removes wastes, bacteria and excess water from the tissue fluid. The fluid present in the lymphatic vessels is called as lymph. In lymph, escaped blood cells and proteins are collected and returned back to the heart in the form of interstitial fluid. Interstitial fluid is a fluid that bathes the cells of multicellular animals.

Thus, the correct answer is 'Returns interstitial fluid back to heart.'
