After completing a moderate intensity level physical activity, how is a person most likely to feel?

Tired, sore, and their muscles will probably burn from fermentation in the muscles to give them extra ATP (energy).

Tired and exhausted
thats why we sweat, to keep your body cool

Air goes past the epiglottis and into the trachea when you breathe in. from there, it goes to your vocal cords in the larynx until it reaches the bronchi. from the bronchi, air passes into each lung.
