monitta

You will run and breathe heavily for a long period of time. is affecting your pH levels, Lowering the pH, making it more acidic.

  • A. Lowering the pH, making it more acidic.

<h3>How does respiratory rate affect pH?</h3>

When it is respiratory, it occurs due to an increase in the amount of volatile acids in the body, which lead to an increase in pCO2. When it is metabolic, it occurs due to the accumulation of non-volatile acids, which lead to the loss (excessive consumption) of bases, mainly bicarbonate, causing a drop in pH.

With this information, we can conclude that By eliminating carbon dioxide during expiration, pulmonary ventilation reduces the acidity of the blood, helping it to maintain the desired alkalinity level.

Explanation:

Options for this question are:

  • <em>Reservoir.</em>
  • <em>Biotic community.</em>

The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.

<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.
