true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thor
faltersainse [42]

The thorax is a very vital and important organ in the human body.

  • It is a structure that serves as a<u> </u><u>protective covering</u> for organs in the body such as<u> the lungs, the heart, some vital blood vessels</u> e.t.c

It is<u> false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>

  • When a person breathes in,  <u>the chest cavity expands (the volume increases) and the pressure in the thorax decreases.</u>

  • When a person breathes out, <u>the chest cavity decreases in size, and the pressure in the thorax increases. </u>

  • Therefore, we can see that the <u>process of breathing in humans</u>, follows the <u>principle of Boyle's Law.</u>

  • Boyle's law states that as the<u> volume increases there is a decrease in pressure</u> and <u>as the volume decrease there is an increase in pressure. </u>

Therefore, It is <u>false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>
