Low alveolar po2 can be caused by one of two mechanisms. one of them is that the inspired air has low oxygen content. what is the other reason? low alveolar po2 can be caused by one of two mechanisms. one of them is that the inspired air has low oxygen content. what is the other reason? a) hypoventilation b) low hematocrit c) high altitude d) low hemoglobin concentration.

a. Hypoventilation

Explanation:

Hypoventilation

(Hypo means below)

It's poor gas exchange caused by low ventilation that results in accumulation of carbon dioxide (hypercapnia) and respiratory acidosis.

Another term for Hypoventilation is respiratory depression

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
