Answer #1

ANSWER :

The amount of air that could be inhaled and exhaled through lungs normally without any effort is called tidal volume (TV). IT is about to 500ml in adult healthy person However, it is found to be increased in athlete person and do breathing exercise. Hence, increased amount of tidal volume enhance the supply of PO2 in lungs.

    Let us assume that a seal's lungs makes up 10% of its body's volume when full, and that the average density of a seal is 980 kg/m3 when its lungs are full. If the air in the seal's lungs obeys Boyle's law, at what depth would this seal achieve neutral buoyancy in sea water, which has a density of 1020 kg/m3? Assume there are no changes to other tissues in the seal as it dives and that atmospheric pressure is...

    Researchers set out to conduct a series of separate experiments to explore how the mammalian respiratory system functions. Using rats as a model for exploring respiration (assume the mechanics for breathing and maintaining homeostatic regulation of Pco2, Po2, and pH are the same for humans and rats), the researchers performed several separate experiments on these otherwise healthy rats. The rats were allowed to fully recover after the conclusion of each experiment, thus ensuring no carry over effects from one experiment...
