Cilia are important in mechanical removal of the bacteria from the upper respiratory tract.

A loss of 50% of a person’s functional skin surface would lead to a gross exposure of the underlying tissues to the environment leading to excessive dehydration due to fluid loss from evaporation and exposure of the underlying tissues to the risk of infection due to loss of barrier.

Osteoporosis is a disease of calcium depletion from bones rendering then weak and fragile. The calcium metabolism in case of females is dependent on estrogen receptors on
