Systemic arteriolar constriction may result from an increase in the local concentration of which of the following: O a. Nitric oxide. O b. Hydrogen ion. O C. Atrial natriuretic peptide. O d. Angiotensin II. O e. Adenosine. At sea level, PO2 in atmospheric air is 160 mmHg, it decreases to 150 mmHg in the anatomical dead space following inspiration, the reason behind this drop is: O a. Oxygen is consumed by the bronchi and bronchioles O b. Excessive mucous secretion of the anatomical dead space O C. Presence of water vapor in anatomic dead space O d. Absence of CO2 in anatomic dead space O e. PN2 in anatomic dead space is the highest among other gases

I need the answer as soon as possible
Transcribed Image Text:Systemic arteriolar constriction may
result from an increase in the local
concentration of which of the
following:
O a. Nitric oxide.
O b. Hydrogen ion.
O C. Atrial natriuretic peptide.
O d. Angiotensin II.
O e. Adenosine.
At sea level, PO2 in atmospheric air
is 160 mmHg, it decreases to 150
mmHg in the anatomical dead
space following inspiration, the
reason behind this drop is:
O a. Oxygen is consumed by the
bronchi and bronchioles
O b. Excessive mucous secretion
of the anatomical dead
space
O C. Presence of water vapor in
anatomic dead space
O d. Absence of CO2 in anatomic
dead space
O e. PN2 in anatomic dead space
is the highest among other
gases
