Difference between inhalation and exhalation five difference
Answers
Answer:
Inhalation is the process of intake of air into lungs, whereas exhalation is the process of letting air out from lungs.The composition of air which is inhaled is oxygen and nitrogen mix, while the composition of air which is exhaled is carbon dioxide and nitrogen mix. Inhalation begins with the contraction of muscles attached to the ribcage causing expansion in the chest cavity, where contraction of the diaphragm sets in resulting in the expansion of the intrapleural space and a rise in the negative pressure as per Boyle’s law.Exhalation happen eventually, the area in the chest reduces and carbon dioxide-rich air is expelled out of the lungs and windpipe, ultimately out of the nose,Inhalation occurs through active contraction of the muscles such as the diaphragm and is the action of breathing in whereas exhalation is the act of exhaling air taken in and is passive.
