Answer to q. 1

Inhibiting carbonic anhydrase will cause CO2 to build up in the blood. This will trigger the brain and carotid sensors to trigger a faster rate of breathing. This in turn will increase the oxygen supply to the tissues. However, the drug does not improve physical performance (although it may alleviate symptoms of altitude sickness that could make a person less effective) and it will not help people who are at such a high altitude that they can't get enough oxygen even if they breathe faster.

Answer to q. 2

The lymphatic system is composed of capillaries connected to veins that join and empty fluid into the systemic circulation near the heart. The movement of lymph is powered by muscle contraction and directed by valves in the vessels. The capillaries collect fluid from the tissues, preventing edema. The system, with its nodes and associated thymus and spleen, function in immunity by filtering debris and maintaining a supply of white blood cells
