Describe the effect that exercise has on tidal volume, alveolar ventilation, and anatomical dead space compared to the resting rate based upon the data in the lab.

Exercise or any other physical activity, increases the oxygen demand in the lungs and affects the flow of air into the lungs.

Tidal Volume: The amount of air inspired (air that leaves or enters the lungs) during breathing is called tidal volume.  With the increase in physical activity such as exercise, the tidal volume increases to allow more gaseous exchange. During exercise, the amount of air to be inhaled increases, thus the tidal volume also increases.

Alveolar Ventilation: It is also known as alveolar volume. It is the amount of air that enters the alveoli in one minute. Alveolar ventilation also increases with the increase in the vital volume due to exercise. This is because oxygen demand increases during exercise.

Anatomical Dead Space: It refers to the air that is directed towards the alveoli but does not participate in the gaseous exchange It decreases during exercise due to increase in ventilation.

Exercising has a lot of effects on our body and brain. Physical exercise stimulates diverse brain chemicals that may have you feeling better and more relaxed. You will also feel happier about your appearance when you exercise regularly.

>Tidal Volume: This refers to the amount of air entering the lungs during breathing.  An increase in exercise results in tidal volume since this allows for a greater gaseous exchange.

 
>Alveolar Ventilation: Also called as alveolar volume, this refers to the amount of air in 1 minute that passes the alveoli. Just like tidal volume, alveolar ventilation increases with increasing exercise intensity.

>Anatomical Dead Space: This is the amount of air that enters the alveoli but has no direct participation in the gaseous exchange. This decreases during exercise due to an increase in ventilation.
