During physical activity of moderate intensity, your heart will beat at a percentage of its maximum rate. what is the target heart rate for moderate-intensity activity? 40% to 50%

There are choices for this question namely: 

a. 40% to 50%
b. 50% to 70% 
c. 70% to 85%
d. 85% to 100%

The correct answer is 50% to 70%. Moderate-intensity activity is noted when a person reaches 50% to 70% of his or her maximum heart rate in exercise. The maximum heart rate is determined by subtracting the age to 220. 

For example, a 54-year-old male with type 2 diabetes needs to have moderate intensity activity. His maximum heart rate is (220-54) which is 166 bpm. 50% to 70% of 166 is 83-116 bpm. Therefore he should exercise and raise his heart rate at 83-116 bpm. 

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.
