TRUE OR FALSE<br> Oxygen is absorbed into the bloodstream in the trachea?
Arte-miy333 [17]

False. Oxygen is absorbed in the alveoli sacs of the lungs.

Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.

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.
