B. pH of the blood increases. C. blood becomes more acidic. D. number of hydrogen ions in the blood decreases. E. blood becomes more alkaline. The nasal septum A. divides the nose into superior and inferior chambers. B. forms the floor of the nasal cavity. C. is the opening of the nose to the outside environment. D. is the part of the nose responsible for the sense of smell. E. divides the nose into right and left chambers.

12.d.Liver, gall bladder
13c.helps prevent the alveoli from collapsing.
14c.Hypercapnia is generally defined as a blood gas carbon dioxide level over 45 mmHg. Since carbon dioxide is in equilibrium with carbonic acid in the blood, hypercapnia can drive serum pH down, resulting in a respiratory acidosis.
15.E. Divides the nose into right and leeft chambers.
16.e.Sound- When the air passes through the elastic vocal folds and causes them to vibrate, the type of phonation is called voicing. The vocal folds give the singer a wide range of control over the pitch of the sound produced.
17.E.All are correct.
18d.Alveoli are the primary site of gas exchanges in the lungs.
19.c. small intestine-it is the primary site for the absorption of the nutrients.
20.d.Bound by the red blood cells.
21.c.Lymphatic vessels in the lining of small intestine.
22.e.directly eliminates waste from the body.
23.e pharynx
