Air in the anatomic dead space must be subtracted from the minute volume to determine alveolar minute volume because:

A. more air is in the anatomic dead space than in the alveoli.
B. the same amount of air remains in the anatomic dead space with every respiration.
C. air in the anatomic dead space determines the rate of respiration.
D. air in the anatomic dead space determines how much air can reach the alveoli.

Anatomical dead space refers to the air within the respiratory structures that never participate in gas exchange as it does not reach functional alveoli. In the respiratory system, both anatomical and alveolar dead spaces exist, contributing to total dead space which represents air not used in gas exchange.

Dead space can have a severe impact on breathing due to reduced gas diffusion. Anatomical dead space, caused by anatomical failures, is important to consider when calculating alveolar minute volume by subtracting it from the minute volume.
