Answer to Problem 17A

Correct answer:

The correct answer is option (A) inhalation.

Explanation of Solution

Explanation/justification for the correct answer:

Option (A) inhalation. During the process of inhalation, the lung volume expands because of the contraction of the diaphragm and intercostal muscles (the muscles that are linked to the rib cage), hence enlarge the thoracic cavity.So, the correct answer is option (A).

Explanation for incorrect answer:

Option (B) exhalation. During exhalation, the lungs recoil to force the air out of the lungs. The intercostal muscles relax, returning the chest wall to its real position. So, this is an incorrect answer.

Option (C) cellular respiration. It the process via which organisms combineoxygenwith foodstuffmolecules, diverting thechemical energyin these materials into life-sustainable functions and discarding, as waste substances,carbon dioxide, and water. So, this is an incorrect answer.

Option (D) filtration. Glomerular filtration is the first step in making urine. It is the process that our kidneys use to clean extra fluid and waste products out of the blood into the urine accumulating tubules of the kidney, so they will be discarded from your body. So, this is an incorrect answer.
